The slope of the blue curve measures the plane's . the unit of measurement for the slope of the curve is . at point a, the slope of the curve is , which means that the plane is at a rate of feet per minute. at point b, the slope of the blue curve is , which means that the plane is at a rate of feet per minute.

Taking square root on both sides, that becomes 2x - 5 = (+/-) √11

Then:

2x = (+/-)√11 + 5

x = [5 +/- √11 ] / 2

x = 5/2 +/- (√11)/2

That is, x = 5/2 +(√11)/2 and x = 5/2 - (√11)/2

Step-by-step explanation:

To find the number of hours Carla worked, we'll set up and solve equations based on the information given.

To solve this problem, we'll set up an equation based on the information given.

Let x be the number of hours Carla worked last week and y be the number of hours she worked this week.

According to the problem, 15 more than twice the hours Carla worked last week is the same as three times the hours she worked this week decreased by 15:

2x + 15 = 3y - 15

Next, we'll set up another equation based on the fact that Carla worked the same number of hours each week:

x = y

We can now solve this system of equations to find the value of y, which represents the number of hours Carla worked this week:

Substituting y for x in the first equation: 2y + 15 = 3y - 15

Combining like terms: 15 = y - 15

Adding 15 to both sides: 30 = y

So, Carla worked 30 hours this week.

Answer: 8.

Step-by-step explanation: since the y coordinates are the same number and they are both positive you move to the x coordinates and you subtract them since they are both negative and you'd get a positive 8. Have a Blessed Day! :D

To find the distance between two points in a coordinate plane, you can use the distance formula. In this case, the distance between point G (-4, 1) and point H (-12, 1) is 8 units.

To find the distance between two points in a coordinate plane, you can use the distance formula. The distance formula is derived from the Pythagorean theorem and is given by:

distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)

In this case, the coordinates of point G are (-4, 1) and the coordinates of point H are (-12, 1).

So, substituting the values into the distance formula:

distance = sqrt((-12-(-4))^2 + (1-1)^2)

Simplifying that expression, the distance between point G and point H is 8 units.

Answer:

C. $25

Step-by-step explanation:

We will find,

The slope of the function using [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex].

Taking the points (1,40) and (2,55).

Slope = [tex]\frac{55-40}{2-1}[/tex]

i.e. Slope = [tex]\frac{15}{1}[/tex]

i.e. Slope = 15

Substituting the slope and point (1,40) in the equation [tex]y=mx+b[/tex],

We have, [tex]40=15\times 1+b[/tex]

i.e. [tex]b=40-15[/tex]

i.e. b= 25

Thus, the equation of the linear function is [tex]y=15x+25[/tex].

This linear function represents the cost of the comic book since Lucy purchased it, where x= years.

So, the initial value of the comic book is when x= 0.

So, [tex]y=15\times 0+25[/tex] i.e. y= 25

Hence, the cost of the book when Lucy purchased it was $25.

Step-by-step explanation:

Answer:

The slope of the function is 5.

Step-by-step explanation:

Remember that to calculate the slope of any function you just need the equation of the function on slope form: y=mx+c or any two points in the graph that are result of the function, in this case we have a table, and we will use the first two points:

(-4,-16)

(-2.-6)

So the formula for slope is:

[tex]\frac{y2-y1}{x2-x1}[/tex]

We insert the values of our two points:

[tex]\frac{y2-y1}{x2-x1} \\\frac{-6-(-16)}{-2-(-4)}\\\frac{10}{2}\\  Slope=5[/tex]

So the slope of the function is 5.

Answer:

In general the two other decimals are x and y that satisfy x + y = 1.66 where x ≤ .99 and y ≤ .99

One particular pair would be x = 0.99 and y = 0.67

Step-by-step explanation:

If Holland added three decimals that made a sum of 2 and one of them was 0.34, we are going to name x and y to the other 2 decimals.

We are going to write the equation:

[tex]0.34 + x +y= 2\\x+y=2-0.34\\x+y = 1.66[/tex]

So we have that both the other numbers have to sum 1.66, however, we know both numbers are decimals so neither one of them can be greater than 1.

So this problem has many answers and the answers would be all the numbers that satisfy x + y = 1.66 where x ≤ .99 and y ≤ .99

y = 1.66 -0.99 = 0.67.

And our pair of numbers would be 0.99 and 0.67.

y = 1.66 - 0.80 = 0.86

And our pair of numbers would be 0.80 and 0.86

This way, we can find more than 1 answer for the other two decimals.

A number line is shown from negative 10 to 0 to positive 10. There are increments of 2 on either side of the number line. The even numbers are labeled on either side of the number line. An arrow pointing from 0 to negative 6 is shown. Above this, another arrow pointing from negative 6 to negative 2 is shown. A vertical bar is shown at the tip of the arrowhead of the top arrow.

Answer:

The correct option is B) A number line is shown from negative 10 to 0 to positive 10. There are increments of 2 on either side of the number line. The even numbers are labeled on either side of the number line. An arrow pointing from 0 to negative 6 is shown. Above this, another arrow pointing from negative 6 to negative 2 is shown. A vertical bar is shown at the tip of the arrowhead of the top arrow.

Step-by-step explanation:

Consider the provided expression.

−6 − (−4)

Open the parentheses and change the sign.

−6 − (−4)

−6 + 4

Subtract the numbers.

−2

Now draw this on number line.

First draw a number line is shown from −10 to 0 to 10. with scale of 2 unit on either side of the number line. Draw an arrow pointing from 0 to −6 Which show −6. Above this, another arrow pointing from −6 to −2 which shows −6 − (−4) = −2. A vertical bar is shown at the tip of the arrowhead of the top arrow.

The required number line is shown in the figure 1.

Hence, the correct option is B) A number line is shown from negative 10 to 0 to positive 10. There are increments of 2 on either side of the number line. The even numbers are labeled on either side of the number line. An arrow pointing from 0 to negative 6 is shown. Above this, another arrow pointing from negative 6 to negative 2 is shown. A vertical bar is shown at the tip of the arrowhead of the top arrow.

This is about understanding slopes.

Option A is correct.

y = -10x + 6  - - - (eq 1)

y - 36 = 8(x - 4)  - - - (eq 2)

y = mx + c

Where m is slope and c is the y intercept.

Let's expand eq 2 to be in the form of y = mx + c

Thus;

>>y - 36 = 8(x - 4)

>> y - 36 = 8x - 32

>> y = 8x - 32 + 36

>> y = 8x + 4  - - - (eq 3)

Thus, slope of eq 1 is -10 and y-intercept is 6.

Similarly, slope of eq 3 is 8 and y-intercept is 4.

This means y = -10x + 6 has a greater y-intercept than y - 36 = 8(x - 4).

Also, the slope in y - 36 = 8(x - 4) which is 8 will slope to the right while the slope of y = -10x + 6  which is -10 will slope to the left. This means that line represented by y = -10x + 6  has a steeper slope.

This is because the higher the slope, the steeper the line.

After rewriting both equations in slope-intercept form, we find that the function y = -10x + 6 has a steeper slope and the function y - 36 = 8(x - 4) has a greater y-intercept, making option (b) the correct answer.

The question involves comparing the slopes and y-intercepts of two linear functions, represented by the equations y = -10x + 6 and y - 36 = 8(x - 4). To compare them, we need to write both equations in slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.

The first equation, y = -10x + 6, is already in slope-intercept form, with a slope of -10 and a y-intercept of 6. For the second equation, y - 36 = 8(x - 4), we first distribute the 8 to get y - 36 = 8x - 32 and then add 36 to both sides to get the slope-intercept form, y = 8x + 4, which has a slope of 8 and a y-intercept of 4.

Comparing the slopes, -10 for the first equation and 8 for the second, we see that the first equation has a steeper slope because -10 has a greater magnitude than 8. Comparing the y-intercepts, 6 for the first equation and 4 for the second, the first equation has a greater y-intercept. Therefore, the correct statement regarding their slopes and y-intercepts is (b) The function that is represented by the equation y = -10x + 6 has a steeper slope and the function that is represented by the equation y - 36 = 8(x - 4) has a greater y-intercept.
