Please help me out! Will mark brainliest and a thank you! A) Teddy has 144 small cubes that are 1cm on each side. He also has a box that is 7cm long, 6cm wide, and 4cm high. How many MORE small cubes does Teddy need to fill the box completely?

B) Another box with different dimensions can fit the same number of 1cm cubes as the first box. What could the dimensions of this other box be?

a. The slope is and the y-intercept is 0

b. The slope is and the y-intercept is

c. The slope is and the y-intercept is 2

Step-by-step explanation:

The easiest way to find the slope and y-intercept is to put each equation in the slope-intercept form

That is:

y = mx = c

where m is the slope and c is the y-intercept

Part a:

6(x+y) = 3(x-y)

2(x+y) = x-y

2x + 2y = x - y

3y = -x

Comparing this with the general formula, we can conclude that:

The slope is and the y-intercept is 0

Part b:

2(x+y) = 5(y+1)

2x + 2y = 5y + 5

3y = 2x - 5

Comparing this with general formula, we can conclude that:

The slope is and the y-intercept is

Part c:

5x + 10y -20 = 0

10y = -5x + 20

Comparing this with the general formula, we can conclude that:

The slope is and the y-intercept is 2

Hope this helps :)
