question 6

-5x+6y=12

6y=12+5x

6y=5x+12

y=⅚x +12/6

y=⅚x +2

question 7

slope m =-5

intercept c =7

y=mx+c

y=-5x+7

question 8

(a) y=mx-45x

y=x(m-45)

(b) y=120(m-45)

question 10

(8 -2)

x1=8

y1=-2

m=3

m=(y-y1)/(x-x1)

3=(y+2)/(x-8)

3(x-8)=y+2

3x-24=y+2

3x-y-24-2=0

3x-y-26=0

The volume of a gift box is 972 in. The height of the gift box is 12 inches

Serggg [28]

Answer:

The length of each side of the 9 in

Step-by-step explanation:

The volume of the gift box is 972 in. The height of the gift box is 12 inches

and the area of the base is 81 in².

We want to determine the length of each side of the square base if the base shape is a square.

Recall that, the area of a square is

${l}^{2}$

It was given that, the area of this base is 81 in²

${l}^{2} = 81$

Take positive square root:

$l = \sqrt{81} = 9in$
