2. A cube is made up of six congruent square faces. Find the length of the inner diagonal of the cube. Note that is the hypotenu

se of right triangle ADH. (Round your answer to the nearest hundredth.)
a) Use the 45-45-90 property or the Pythagorean Theorem to find the length of the diagonal (DH) of the bottom base of the cube.
b) Use the length from part a as one leg, the length of side AD, and the Pythagorean Theorem to find the length of the diagonal AH.

Answer:

First question: (0, 1) (-4, 0)

Step-by-step explanation:

FIRST QUESTION:

y=3x+1

y=x-7

In the first equation of the first question, (y=3x+1) the 3 represents the slope and the 1 represents the y-intercept. Therefore, your first coordinate is (0, 1).

To figure out the second coordinate, do this:

Substitute y for x-7

x-7=3x+1

Combine like terms

x=3x+8

-3x+x=8

-2x=8

Divide the entire equation by -2

x=-4

Therefore, your second coordinate is (-4, 0).

SECOND QUESTION:

I am really sorry, I can't see the second question very well. It's a little too blurry and I have bad eyesight.

Hope this helps a little.
