Let f(x) = 3x2 x − 3 and g(x) = x2 − 5x 1. find f(x) − g(x). select one:
a. 2x2 − 4x − 2
b. 2x2 − 4x − 4
c. 2x2 6x − 2
d. 2x2 6x − 4

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?
