There's no way to answer that with the information given.
' Y ' might be -0.4x . Then, when ' x ' is 5, ' y ' is -2 .
OR, ' y ' could be x-14. Then, when ' x ' is 5, ' y ' is -9 .
There's just not enough given information to know.

Answer:
Your solution is (1, -4)
Step-by-step explanation:
The equations both equal <em>y</em>, so you can set them equal to each other.
y = -4x
y = -3x - 1
-4x = -3x - 1
add 3x to both sides
-x = -1
divide both sides by -1 for x to be positive
x = 1
plug x back in
y = -4(1)
y = -4
y = -3(1) - 1
y = -3 - 1
y = -4
Your solution is (1, -4)

Answer:
The room dimensions for a minimum cost are: sides of 10 feet and height of 8.75 feet.
Step-by-step explanation:
We have a rectangular room with sides x and height y.
The volume of the room is 875 cubic feet, and can be expressed as:
With this equation we can define y in function of x as:
The cost of wall paint is $0.08 per square foot. We have 4 walls which have an area Aw:
The cost of ceiling paint is $0.14 per square foot. We have only one ceiling with an area:
We can express the total cost of painting as:
To calculate the minimum cost, we derive this function C and equal to zero:
The sides of the room have to be x=10 feet.
The height can be calculated as:
The room will have sides of 10 feet and a height of 8.75 feet.
