Answer:

25 4-point questions and 75 2-point questions

Step-by-step explanation:

Let x = no. of 4-point questions

Then 3x = no. of 2-point questions

So, x + 3x = 100

4x = 100

x = 25 =  no. of 4-point questions

and 3x =  3(25) = 75 = no. of 2-point questions

Answer:

y = -x+8

Step-by-step explanation:

The side that is parallel to BC is EF

Find the slope of EF:

m = \frac{2-4}{6-4} =\frac{-2}{-2} =-1

Easiest way is just put the formula in point-slope form and simplify.

Let's use point F, which is (6,2)

y -2=-(x-6)

Simplify:

y-2=-x+6

Add 2 on both sides:

y = -x+8

Hope this helped

To find volume, you plug the area in the volume formula

v=1/3 ah

v=1/3 (3)(3)

1/3(9) would be 3 cubic cm

I'm working on something like this too.
You want to get the measure of y.

4x - 2y = 10
-4x -4x
------------------
-2y = 4x + 10
----- ---- ----
-2 -2 -2
y = -2/1x + -5
m = -2
b = -5
