The mixed number -8 3/4 can be converted to an improper fraction by multiplying the whole number by the denominator and adding the numerator, resulting in -29/4.
Explanation:The mixed number given is -8 3/4. An improper fraction is one where the numerator (top number) is greater than the denominator (bottom number). To convert a mixed number to an improper fraction, we should multiply the whole number by the denominator of the fraction and then add the numerator. Here, this would look like (-8*4)+3 = -32 + 3 = -29. The denominator stays the same. So, -8 3/4 is equal to -29/4 in improper fraction form.

A function f satisfies the following conditions: f(5)=20, f'(5)=2, and f"(x)<0, for x>=5. Which of the following are possible values for f(7)? possible choices are 28, 20, 26, 24, 22
Given the function's conditions, the value of f(7) must be less than or equal to 24 due to the concave-down nature indicated by the negative second derivative, making 20, 22, or 24 possible values for f(7).
Explanation:The student asked about determining possible values for a function f(x) given a set of conditions: f(5)=20, f'(5)=2, and f"(x)<0 for x>=5. The negative second derivative indicates that the function is concave down for x>=5, meaning the rate of increase of f(x) is decreasing. Starting at x=5 with a value of 20 and a slope of 2, we can deduce that after moving 2 units to x=7, the value of f(7) cannot be greater than what it would be if f(x) were linear, since f"(x)<0 implies the function's rate of growth is decreasing. Therefore, f(7) must be less than or equal to 20 + 2*(7-5), which is 24.
Since the rate of increase is decreasing and the function cannot increase at a rate faster than the initial slope of 2, the possible values for f(7) among the given choices must be less than or equal to 24. Thus, the possible values for f(7) could be 20, 22, or 24.

The value of f(7) is 24.
Given the function f with conditions f(5)=20, f'(5)=2, and f''(x)<0 for x ≥ 5, we need to find possible values for f(7) from the choices given: 28, 20, 26, 24, and 22.
Here is a step-by-step solution:
f(5)=20 indicates that at x=5, the value of the function is 20.f'(5)=2 tells us that the slope or the derivative at x=5 is 2, which implies the function is increasing at this point.f''(x)<0 for x ≥ 5 indicates that the function is concave down, meaning its slope is decreasing as x increases.Since the function is concave down, the rate of increase of the function will decrease as x moves from 5 to 7:
f(x) initially increases from 5 to 7 with a slope of 2, so f(7) cannot be lower than f(5): 7 − 5 = 2 * 2 = 4, thus the function increases by at most 4 from 5 to 7.So the maximum possible value considering the concavity is 20 + 4 = 24.Therefore, among the choices 28, 20, 26, 24, and 22, the possible value for f(7) given the conditions is 24.

the number of roses was 15 greater than twice the number of prunes. if the roses and prunes totaled 255, how many roses were there?
The problem is a simple algebraic equation that, when solved, shows there were 175 roses.
To solve the problem given by the student, we need to set up an equation based on the information provided. We are told that the number of roses was 15 greater than twice the number of prunes, and together they totaled 255.
Let the number of prunes be p. Then the number of roses can be represented as 2p + 15. Adding these amounts must total 255, so we can write the following equation:
2p + 15 + p = 255
Combining like terms:
3p + 15 = 255
Subtracting 15 from both sides of the equation:
3p = 240
Dividing both sides by 3:
p = 80
Now that we have the number of prunes, we can find out the number of roses:
Roses = 2p + 15 = 2(80) + 15 = 160 + 15 = 175
Therefore, the student had 175 roses.
Which equation represents the line that passes through (–6, 7) and (–3, 6)?
Answer:
Equation of line become [tex]y= \frac{- 1 *x}{3}+ 5[/tex].
Step-by-step explanation:
slope of the line
we know that the formula to calculate the slope between two points is equal to
Slope (m) = [tex]\frac{y_{2}- y_{1} }{x_{2}-x_{1}}[/tex].
substitute the values
(m) = [tex]\frac{6 - 7} }{ -3 - (-6)}[/tex].
(m) = [tex]\frac{-1} }{3}[/tex].
With the slope m and the point (-6, 7) find the equation of the line
we know that
the equation of the line in the point-slope form is equal to
[tex](y - y_{1}) = m ( x - x_{1})[/tex].
substitute the values
[tex](y - 7) = \frac{-1}{3} (x - ( -6))[/tex].
[tex](y - 7) = \frac{-1}{3} (x + 6)[/tex].
[tex](y - 7) = \frac{-x}{3} +2 )[/tex].
On adding both sides by 7.
[tex]y= \frac{-x}{3} - 2 + 7 [/tex].
[tex]y= \frac{-x}{3}+ 5[/tex].
Therefore, equation of line become [tex]y= \frac{-1 *x}{3}+ 5[/tex].
Paper cost $49 for 10 reams. How much for 1 ream?
To calculate the cost of 1 ream of paper from the total cost of 10 reams, divide $49 by 10 to get $4.90 per ream.
To find out how much it costs for 1 ream of paper when 10 reams cost $49, we simply divide the total cost by the number of reams. In this case:
Cost per ream = Total cost / Number of reams
Cost per ream = $49 / 10
Cost per ream = $4.90
Therefore, the cost for 1 ream of paper is $4.90.
Yolanda is finding 23,567-12,458. She added 2 to 12,458 before subtracting. Then she added it in again after she subtracted. Is her method correct? Explain.
Yolanda's method is incorrect because she should have subtracted the 2 she added before subtracting, not added it. Adding it before and after the subtraction alters the original values and results in an inaccurate subtraction.
Explanation:No, Yolanda's method is not correct. If you add a value to a number before subtracting, you have to subtract that same value after the subtraction, not add it again. This is because the addition of 2 alters the original value of 12,458, making it 12,460, and thus changes the result of the subtraction. However, by adding 2 again after subtracting, Yolanda incorrectly compensates for the initial addition. The correct approach would have been to subtract 2 after the subtraction, returning 12,458 to its original value and ensuring the accuracy of the subtraction.

5. If p || q, which pair of angles must be congruent?
1 and 8
2 and 5
4 and 6
7 and 8
Answer:
1 and 8.
Step-by-step explanation:
Two angles will be congruent if both measure the same. Then, as p is parallel to q we have that the alternate external angles (pair of angles out of the parallel lines, one on the right of the transversal line and the other on the left of the transversal line) has the same measure. In this case, 1 and 8 are alternate external angles.

A graph thAt has a finite or limited number of data points is
The correct answer is:
Discrete graph.
Explanation:
A discrete graph is a graph of disconnected points.
Since they are disconnected, this means the graph only has values at the points drawn, not between.
The opposite of a discrete graph is a continuous graph; it is a graph of connected points. Since the points are connected, the graph has values between all of the points. This is similar to what we learned in geometry about a line; a line has an infinite number of points. This is true of the connections between points in a continuous graph.
Since a discrete graph is the opposite of a continuous graph, this means it does not have an infinite number of points; a discrete graph has a finite number of points.
