Step-by-step explanation:I’m probably doing this wrong but... if you take two away from the seven and add it to 7:58 you get 8:00. But you still have the remaining 5 minutes so you simply add it to the 5:00 and get 5:05.
let x be an integer that satisfies x^4 + 24 = 105. what is the value of x^2 - 24?
Answer: -15
Step-by-step explanation:
[tex]x^{4}[/tex] + 24 = 105
subtract 24 from both sides of the equation .
[tex]x^{4}[/tex] = 105 - 24
[tex]x^{4}[/tex] = 81
find the fourth root of both sides
x = 3
Therefore : substitute x = 3 to find the value of [tex]x^{2} -24[/tex]
[tex]x^{2}[/tex] - 24 = [tex]3^{2}[/tex] - 24
= 9 - 24
= - 15
Several properties are used to evaluate this expression. Identify the property used in each step.
21 + (36 + 0 + 19)
21 + (36 + 19):
21 + (19 + 36):
(21 + 19) + 36:
40 + 36
76
Given expression: 21 + (36 + 0 + 19)
Using identity property of addition: a + 0 = a
21 + (36 + 0 + 19) = 21 + (36 + 19)
Using commutative property of addition: a + b = b + a
21 + (36 + 19) = 21 + (19 + 36)
Using associative property of addition: a + (b + c) = (a + b) + c
21 + (19 + 36) = (21 + 19) + 36
Now, add two numbers inside the bracket.
(21 + 19) + 36 = 40 + 36
Using closure property of addition: a + b = c any number.
40 + 36 = 76
Hence 21 + (36 + 0 + 19) = 76.

1) –10x – y = 0
10x – 4y = 0
Answer:
The solution is (0 ,0)
Step-by-step explanation:
–10x – y = 0 (1)
10x – 4y = 0 (2)
solving by elimination:
(1)+(2)⇒ -5y=0 ⇒ y=0
if we replace y by 0 in the first equation we will get :
–10x – 0 = 0 ⇒ x=0
f(2/9) if f(x)=3x+1/3 x=2/9
Answer:
[tex]f(\frac{2}{9})=1[/tex]
Step-by-step explanation:
we have
[tex]f(x)=3x+\frac{1}{3}[/tex]
we know that
f(2/9) is the value of the function f(x) when the value of x is equal to 2/9
so
For x=2/9
substitute the value of x in the function and solve for f(x)
[tex]f(x)=3(\frac{2}{9})+\frac{1}{3}[/tex]
[tex]f(x)=\frac{2}{3}+\frac{1}{3}[/tex]
[tex]f(x)=\frac{3}{3}[/tex]
[tex]f(x)=1[/tex]
therefore
[tex]f(\frac{2}{9})=1[/tex]
Keshawn is asked to compare and contrast the domain and
range for the two functions.
which statements could he include in his explanation?
Select two options.
f(x) = 5x
g(x) = 5
The domain of both functions is all real numbers.
The domain of f(x) is x > 5.
The domain of g(x) is x > 5.
The range of f(x) is y> 0.
The range of g(x) is y > 0.
Answer:
First and Last Option.
Step-by-step explanation:
Took the test!
Keshawn could include the following statements in his explanation:
The domain of both functions is all real numbers.
The range of f(x) is y > 0.
The range of g(x) is y > 0.
Options A, D, and E are the correct answer.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
f(x) = 5x
g(x) = 5
The domain of a function is the set of all possible input values.
The range of a function is the set of all possible output values.
Now,
For both of these functions, the domain is all real numbers.
This is because we can plug in any value for x and get a valid output.
For example:
If we plug in x = 0, we get.
f(0) = 5(0) = 0
g(0) = 5
For both functions, we get a valid output, even though they are different. We can do this for any real number value of x.
Now,
For f(x) = 5x, the range is y > 0.
This is because the function produces positive output values for any positive input value of x, and negative output values for any negative input value of x.
The only value for which f(x) produces a zero output is x = 0, but this is not included in the range since it is not greater than zero.
For g(x) = 5,
The range is also y > 0.
This is because the function produces a constant output of 5 for any value of x. Since 5 is greater than zero, the range of g(x) is also y > 0.
Thus,
The domain of both functions is all real numbers.
The range of f(x) is y > 0.
The range of g(x) is y > 0.

What is the y-intercept of the line given by the equation below? Enter your answer as an ordered pair.
y = 2x + 10
Final answer:
The y-intercept of the equation y = 2x + 10 is 10, which means the ordered pair for the y-intercept is (0, 10).
Explanation:
The y-intercept of the line given by the equation y = 2x + 10 can be found by looking at the equation in its slope-intercept form, which is y = mx + b. Here m represents the slope of the line, and b represents the y-intercept. Since the y-intercept is the value of y when x is zero, we can determine that the y-intercept for this line is the constant term in the equation, 10. Therefore, the y-intercept as an ordered pair is (0, 10).
Which graph shows the result of dilating this figure by a factor of 4 about the origin? On a coordinate plane, rectangle A B C D has points (negative 1, 1), (3, 1), (3, negative 1), (negative 1, negative 1). On a coordinate plane, rectangle A prime B prime C prime D prime has points (negative 4, 4), (12, 4), (12, negative 4), (negative 4, negative 4). On a coordinate plane, rectangle A prime B prime C prime D prime has points (negative 2, 2), (6, 2), (6, negative 2), (negative 2, negative 2). On a coordinate plane, rectangle A prime B prime C prime D prime has points (negative 0.25, 0.25), (0.75, 0.25), (0.75, negative 0.25). (negative 0.25, negative 0.25). On a coordinate plane, rectangle A prime B prime C prime D prime has points (negative 0.5, 0.5), (1.5, 0.5), (1.5, negative 0.5), (negative 0.5, negative 0.5).
Answer:
Second option: On a coordinate plane, rectangle A'B'C'D' prime has points [tex](-4,4),(12,4),(12,-4),(-4,-4)[/tex]
(See the graph attached)
Step-by-step explanation:
For this exercise it is importnat to know that a Dilation is defined as a transformation in which the Image (The figure obtained after the transformation) has the same shape as the Pre-Image (which is the original figure before the transformation), but they have different sizes.
In this case, you know that the vertices of the rectangle ABCD ( The Pre-Image) are the following:
[tex]A(-1,1)\\\\B(3,1)\\\\C(3,-1)\\\\D(-1,-1)[/tex]
Therefore, to find the vertices of the rectangle A'B'C'D' (The Image) that results of dilating the rectangle ABCD by a factor of 4 about the origin, you need to multiply the coordinates of each original vertex by 4. Then, you get:
[tex]A'=((-1)(4),(1)(4))=(-4,4)\\\\B'=((3)(4),(1)(4))=(12,4)\\\\C'=((3)(4),(-1)(4))=(12,-4)\\\\D'=((-1)(4),(-1)(4))=(-4,-4)[/tex]
Finally, knowing those points, you can identify that the graph that shows the result of that Dilation, is the one attached.

The circumference of a circle is 314 units. What is the area?
Answer:
7850 square units
Step-by-step explanation:
According to the question;
Circumference of a circle is 314 units;We are required to find the area of the circle;
First, we need to ask ourselves how we get the perimeter of a circle;Perimeter of a circle = pi × D or 2 pi r
Therefore;
Rearranging the formula;
D = Perimeter ÷ pi
Taking pi to be 3.14
Then;
Diameter = 314 units ÷ 3.14
= 100 units
But, radius = Diameter ÷ 2
= 100 units ÷ 2
= 50 units
We also need to know how we calculate the area of a circle;
Area of a circle = pi×r²
Therefore;
Taking pi as 3.14
Then, Area = 3.14 × 50²
= 7850 square units
Thus, the area of the circle is 7850 square units

[tex]x^{2} +14x=0[/tex]
Step-by-step explanation:
Given:
Given root is
[tex]x=-14,\ 0[/tex]
Now we need to find the quadratic equation for given roots.
Solution:
The given roots are -14 and 0.
So, the sum of the roots.
[tex]\alpha +\beta = -14 + 0[/tex]
[tex]\alpha +\beta = -14[/tex]
Product of the given roots
[tex]\alpha\times \beta = -14\times 0[/tex]
[tex]\alpha\times \beta = 0[/tex]
Therefore, the required quadratic equation is.
[tex]x^{2} -(\alpha +\beta )x+\alpha\times \beta=0[/tex] -------------------(1)
Now we substitute [tex](\alpha +\beta )[/tex] and [tex](\alpha\times \beta)[/tex] in equation 1.
[tex]x^{2} -(-14)x+0=0[/tex]
[tex]x^{2} +14x=0[/tex]
Therefore, the quadratic equation for the given root is. [tex]x^{2} +14x=0[/tex]

7=|3x+9|+7
Answer:
[tex]x=-3[/tex]
Step-by-step explanation:
Given the equation
[tex]7=|3x+9|+7[/tex]
1. Use Addition property of equality, add -7 to both sides:
[tex]7-7=|3x+9|+7-7\\ \\0=|3x+9|[/tex]
2. The absolute value of the number is 0 if and only if the number is 0, so
[tex]3x+9=0[/tex]
3. Use Addition property of equality, add -9 to both sides:
[tex]3x+9-9=0-9\\ \\3x=-9[/tex]
4. Use Division property of equality, divide both sides by 3:
[tex]\dfrac{3x}{3}=\dfrac{-9}{3}\\ \\x=-3[/tex]
The solution is x = -3.
To solve the equation 7 = |3x + 9| + 7, let us follow these steps:
First, we simplify absolute value expression:
7 = |3x + 9| + 7
0 = |3x + 9|
The absolute value of a number is zero only when the number itself is zero. So, we set the expression inside the absolute value equal to zero:
3x + 9 = 0
3x = -9
x = -3
The solution to the equation is x = -3.

Is the centroid of a triangle, the center of the circle cirumdcribing it?
Answer:
No
Step-by-step explanation:
No, only if the triangle is a right triangle.
Final answer:
No, the centroid of a triangle is not necessarily the center of the circle circumscribing it. The centroid and circumcenter are distinct points that coincide only in equilateral triangles.
Explanation:
No, the centroid of a triangle is not necessarily the center of the circle circumscribing it. The centroid is the point of intersection of the medians of the triangle, which are the lines connecting each vertex to the midpoint of the opposite side. On the other hand, the circumcenter of a triangle is the center of the circle that passes through all three vertices of the triangle.
In some cases, the centroid and circumcenter might coincide, but this happens only when the triangle is equilateral. In all other cases, the centroid and circumcenter are distinct points.
For example, an equilateral triangle has its centroid and circumcenter at the same point. However, in an isosceles triangle, the centroid will lie on the line segment connecting the midpoint of the base to the opposite vertex, while the circumcenter will lie on the perpendicular bisector of the base.

Find the magnitude and direction of -5i + 10j
Answer:
|-5i+10j| = 5√5 ≈ 11.18
∠(-5i+10j) ≈ 116.57°
Step-by-step explanation:
The magnitude is given by the Pythagorean theorem:
|-5i+10j| = √((-5)² +10²) = √125 = 5√5
The direction is found using the arctangent function. The angle is a second-quadrant angle.
∠(-5i+10j) = arctan(10/-5) ≈ 180° -63.43° = 116.57°

What is the expanded form of 4(7x+3)
Final answer:
The expanded form of 4(7x+3) is achieved by using the distributive property, resulting in the expression 28x + 12.
Explanation:
The expanded form of the algebraic expression 4(7x+3) involves distributing the 4 to both terms inside the parentheses. This is accomplished using the distributive property of multiplication over addition. The steps are as follows:
Multiply 4 by 7x to get 28x.
Multiply 4 by 3 to get 12.
Combine these products to express the expanded form.
Therefore, the expanded form of 4(7x+3) is 28x + 12.
As for evaluating complex expressions such as 2+x(−7+x(2+x(−8+x(−2+3x)))), you would begin by substituting the value of x and simplifying from the innermost parentheses outwards. However, this is a different exercise than simply expanding an algebraic expression.
Which of the following describes the graph of y = x² - 144?
1) The graph has zeroes at x = 12 and x = -12 and it opens upward.
2) The graph has zeroes at x = 12 and x = 12 and it opens upward.
3) The graph has zeroes at x = -12 and x = -12 and it opens downward.
4) The graph has zeroes at x = 12 and x = -12 and it opens downward.
