What is the rate of change for a linear function that passes through the points (8, -10) and (-6, 14)

Anna71 [15]

Answer: $m=-1.714$

Step-by-step explanation:

By definition, the slope of the line is described as "Rate of change".

You need to use the following formula to calcualte the slope of the line;

$m=\frac{y_2-y_1}{x_2-x_1}$

In this case you know that the line passes through these two points: (8, -10) and (-6, 14).

Then, you can say that:

$y_2=-10\\y_1=14\\\\x_2=8\\x_1=-6$

Knowing these values, you can substitute them into the formula for calculate the slope of a line:

$m=\frac{-10-14}{8-(-6)}$

Finally, you must evaluate in order to find the slope of this line. You get that this is:

$m=\frac{-24}{8+6}\\\\m=\frac{-24}{14}\\\\m=-\frac{12}{7}\\\\m=-1.714$

16 question Write a rule for the linear function in the table

Ira Lisetskai [31]

To write the rule or equation of the linear function we need to find the slope of the function first. Using any two points we can find the slope.

Using the first two points (-3, -1) and (0, 2).

Slope (m) of the function would be:

$m= \frac{-1-2}{-3-0}= \frac{-3}{-3} =1$

Using slope and the point (0,2) we can write the equation of the line as:

y - 2 = 1(x-0)
y = x + 2

Thus, the correct rule for the given linear function is x+2

What is the answer to thiss

lana [24]

Hi Student!

This question is fairly simple because it gives us an equation and they also give us a value for the variable that is within the equation and they tell us evaluate the expression. So let's plug in the values and solve.

<u>Plug in the values</u>

$m^2 + 5$

$(9)^2 + 5$

<u>Factor out the exponent</u>

$(9*9) + 5$

$81 + 5$

<u>Combine</u>

$86$

Therefore, the final answer that we would get when substituting m with 9 in the given equation is that we get 86.

Find the volume of a cone with radius 10 feet and height of 4 feet.

Sveta_85 [38]

Answer:

$\frac{400}{3} \pi$

Step-by-step explanation:

Formula for Cone: π $r^{2}\frac{h}{3}$

Since we have all the components, we can find the volume of the cone.

R = 10

H = 4

π $10^{2}\frac{4}{3}$

10×10 = 100

100π $}\frac{4}{3}$

$}\frac{4}{3}$ ×100

4 100 400

--- × ----- = ------

3 1 3

Answer: $\frac{400}{3} \pi$

Hope this helped.
