Answer:
NONE OF THE OPTIONS GIVEN
Step-by-step explanation:
F(x) = 2|x - 3| + 1 is close, but vertical bars in stead of parentheses completely changes the curve shape
I believe it should be f(x) = 2(x - 3) + 1
if g(x) = x
here are some plots to compare the possibilities. I've shifted the vertical of each to separate the blue and green lines slightly. If they were both true "1" values the lines would be colinear for x>3.
The red line has a slope of 1, stretching by a factor of 3 means the slope is now 3. The absolute value signs from the answer options makes f(x) have a sharp V shape whereas the parentheses creates a single line for all values of x as does g(x) = x.
Answer:
The first step to solving the equation is:
Hence, 3x + 24 = 42 is the correct option.
Step-by-step explanation:
Given the equation
First of all, we need to apply the distributive law on the left side of the equation to expand the equation.
So the equation would be expaneded using the distributive law on the left side of the equation
∵ a(b+c) = ab + ac
Therefore, the first step to solving the equation is:
Hence, 3x + 24 = 42 is the correct option.
