Find f(-2) if f(x) = -2x^2+7x-5

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?

Which linear function represents the line given by the point-slope equation y + 1 = –3(x – 5)?

Find the average rate of change for the given function drom x=1 to x=2
