If the coordinates of point E are (-4, y), what is the value of<br> у?

BlackZzzverrR [31]

Answer:

-8

Step-by-step explanation:

First we need to find the slope of CD.

We know C is (-10, -2)

and we know D is (10,6)

If we use the slope formula, we can see the slope is $m=\frac{6-(-2)}{10-(-10)}$

$m = \frac{8}{20} \\m=\frac{2}{5}$

We can see point F is at (6,-4)

We can find the equation of this line by using point slope form, and plugging in F as our point.

$y-(-4)=\frac{2}{5}(x-6)\\y=\frac{2}{5}x-\frac{32}{5}$

To find where E, we need to find the y value when x = -4

$y=\frac{2}{5}(-4)-\frac{32}{5}\\y =-8$

What is the exact area of a circle with a diameter of 10 cm? a. 5πcm^2 b. 10πm^2 c. 25πcm^2 d. 100πcm^2

dalvyx [7]

Answer:

Step-by-step explanation:

a= $\pi$ r^2

To find the radius, divide the diameter by 2

r=d/2

r=10/2

r=5

a= $\pi$ r^2

a= $\pi$ 5^2

a=25 $\pi$

So, choice C is correct

Hope this helps! :)
