First, put the equation of the line giveninto slope-intercept form by solving fory. You get y = 2x +5, so the slope is –2.Perpendicular lines have opposite-reciprocal slopes, so the slope of theline we want to find is 1/2. answer y=-1/2

Let f(x) = x2 − 8x + 5. Find f(−1)

rewona [7]

Answer:

Step-by-step explanation:

$f(x)=x^2-8x+5$

now substitute x for -1

$f(-1)=(-1)^2-8(-1)+5$

now solve

$f(-1)=1+8+5$

$f(-1)=14$

there is your answer! hope this helps! :)
