it would be something like this:
f(x) = 12 + x(4%)
but if you want it in y format then:
y = 12 + x(4%)
Surface area = 12*9 + 2*12*10 + 2*9*10 = 528 in^2 Answer
(its only one 12*9 because it is open at the top)
Answer: (x, y) → (x + 5, y - 7)
<u>Step-by-step explanation:</u>
left and right affect the x-value
up and down affect the y-value
5 to the right means "add 5" to the x-value --> x → x + 5
7 down means "subtract 7" from the y-value --> y → y - 7
6x-4=2x+8
mnus 2x both sides
4x-4=8
add 4 to both sides
4x=12
divide 4 both sides
x=3
