H (x) = 5 x 2^-x
2^-x is the same as saying 1/2^x .
h (x) = 5 x 1/2^x
h (3) = 5 x 1/2^3
= 5 x 1/8
= 5/8
Therefore h (3) = 5/8
Answer:
x = -6
Step-by-step explanation:
-11 - 8x = -3x + 19 (Move constants to right side)
-8x = -3x + 19 + 11 (Move x to left side)
3x - 8x = 30 (simplify)
-5x = 30 (divide both sides by -5)
x = -6
Answer:

Step-by-step explanation:
Given

The number line is missing from the question.
