Find the inverse function of f(x)=4x-8
kipiarov [429]

Answer:

f^-1(x)=1/4x+2

Step-by-step explanation:

y=4x-8

change x and y

x=4y=8

switch sides

4y-8=x

add 8

4y=x+8

divide both sides by 4

y=1/4x+2

substitute f^-1(x) for y

f^-1(x)=1/4x+2

What is the slope of the line?<br> y +3 = -4(x+7)
Svetach [21]

Answer:

  -4

Step-by-step explanation:

Compare this to the form ...

  y -y1 = m(x -x1)

which is the point-slope form of the equation for a line. Matching the parts of the equation, you see that ...

  • y1 = -3
  • m = -4
  • x1 = -7

m represents the slope of the line. The slope is -4.

Which number is irrational? <br><br> A. 0.06¯¯¯¯ <br> B. 49−−√ <br> C. 1/6 <br> D. 17−−√
