Answer:
Solution for y is y = 11 - 6x
For x = -1, the y value is 17
For x = 0, the y value is 11
For x = 3, the y value is -7
Step-by-step explanation:
Solve for y --> y + 6x = 11
y + 6x = 11
-6x -6x
------------------
y = 11 - 6x
Plug -1, 0, and 3 into this equation to find values of y --> x = 11 - y / 6
When x is -1, the y value becomes 17. Secondly, when x is 0, the y value becomes 11. Thirdly, when x is 3, the y value becomes -7.

Answer:
4 gallons of paint
Step-by-step explanation:
We solve using the formula for surface area of rectangular prism.
A=2(wl+hl+hw)
Where:
w = Width
h = Height
l = Length
The pool is 4 feet deep, 18 feet long, and 12 feet wide.
Hence,
=2 × (12 × 18 + 4 × 18 + 4 ×12)
=672 square feet
One gallon of paint covers 155 square feet.
Hence,
155 square feet = 1 gallon of paint
672 square feet = x
Cross Multiply
155 square feet × x = 672 square feet × 1 gallon of paint
x = 672 square feet × 1 gallon of paint/ 155 square feet
x = 4.335483871 gallons of paint
Therefore, based on the calculation above, approximately to the nearest whole number, Sierra uses 4 gallons of paint
