Step-by-step explanation:
I turned the percent into a decimal (.15) then I multiplied the decimal by 50 and got 57.50.
4/7 is not equal to 8/12. It is not equal because if you 4x2= 8 is equal but if you do 7x?= 12 it would be a decimal and you need equal numbers to make it a equivalent fraction. If it was 4/7= 8/14 that would be equivalent.

False. You can find the solution more quickly by solving the system algebraically.
-4x + 2y = 18
Since y=-3x+4,
-4x + 2(-3x+4) = 18
-4x - 6x + 8 = 18
-10x = 10
x = -1
y = -3x+4 = 7
Answer:
f(x) = 4x4 – 7x2 + x + 25 f(x) = 9x4
