Answer:
8
Step-by-step explanation:
Create an expression to model the situation. One can do this by simply rewriting the written expression in terms of numbers and variables. Use the variable (x) to represent the unknown value.

Simplify this expression,

Use inverse operations to solve for (x),

Answer:
x = -7.5
Step-by-step explanation:
12(x+5) = 4x
12x+ 60 = 4x
60 = -8x
-7.5 = x
Answer:
f(-3) = -16
Step-by-step explanation:
Given piecewise function is,
f(x) = 5x - 1 If x < -2
x + 3 If x ≥ -2
We have to find the value of he function when x = -3
Since x = -3 is less than x = -2,
Piece of the function to be considered,
f(x) = 5x - 1
f(-3) = 5(-3) - 1
f(-3) = -16
Answer:
I believe it would be B.
Step-by-step explanation:
Range: area of variation with real numbers
Also, seeing the quadrant it is in means there are negative numbers. This takes out the possibility of option A.
