Need asap 1.which piecewise function is equivalent to the absolute value function and its graph? (the first attachment)
2. which of the following represents a step function? (the second attachment)
3. f(-1/2)equal or opposite to -1 ( the third attachment)

Factor this polynomial completely x^2-64

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?

Asap! will mark brainliest! ( respond asap, it's urgent! : )) what is the slope for equation y =-3x + 8
