Solve for x
-18x+21>-15 or 20x-13>27

All numbers between -2 and 2, not touching -2 or 2

Step-by-step explanation:

-18x+21>-15 simplifies to -18x > 36, which in turn becomes 18x < -36, or

x < -2.

20x-13>27 simplifies to 20x > 40, or x > 2.

Then the solution set is

(-2, 2):  All numbers between -2 and 2, not touching -2 or 2.

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
