Function 1
rate of change = (80-100)/(2-1) = -20
y = -20x + 120
function 2
y = -18x + 120
rate of change = -18
answer
function 2 shows a greater rate of change
Answer:
4x+2
Step-by-step explanation:
Perimeter = 2(width) + 2(length). So 12x+4 = 2(2x) + 2(length) .
12x+4 = 4x + 2(length) then subtract 4x from both sides to get 8x+4 = 2(length). In order to get length by itself you need to divide both side by 2.
4x+2 = length. Hope this helps!
