Answer:
3
Step-by-step explanation:
Cube root of 27 is 3.
3³ = 27.
Make the equations into y = form
-3x+6y=10
-3x+6y=-4
-3x+6y=10
Add 3x to both sides
6y=3x+10
÷6 both sides
Y= 1/2x+5/3
-3x+6y=-4
+3x both sides
6y=3x-4
÷6 both sides
Y=1/2x-2/3
Y= 1/2x+5/3
Y=1/2x-2/3
They have same slope of 1/2
So they are parallel and have different y intercept 5/3 and -2/3
So they do not touch EVER!!
ANSWER IS NO SOLUTION
If they are proportional, then y/x should always be the same.
So 9/2= 4.5
We need to find the y value at x=3 to make y/x equal 4.5
4.5 = y/3
y = 4.5*3 = 13.5
Step-by-step explanation:
<u>Dimensions of the box, considering the base is a square:</u>
- Length = w
- Width = w
- Height = h
(a)
The height is 9 inches greater than the width:
(b)
<u>Express the width in terms of height:</u>
<u>Volume of the box:</u>
- V = base * height
- V = w²h
- V = (h - 9)²h
