We have the expression -1(2x + 3) - 2(x - 1).
Distribute the -1 across the 2x and 3.
-1(2x + 3) - 2(x - 1) = -2x - 3 - 2(x - 1)
Now distribute the 2 across the x and -1.
-2x - 3 - 2(x - 1) = -2x - 3 - 2x + 2
Combine like terms.
-2x - 3 - 2x + 2 = -4x - 1
So, D -4x - 1 is the answer.
Answer:
250
Step-by-step explanation:
First, we need to find h°g, which is the same thing as 
This means that we will take the function 
and will replace each instance of x with 
as that is the value of 
Now that we have our composed function, we can find the y-value when 
20. Using absolute value, make (-10) turn into 10 and do 10 + 10 = 20
Y=-.5x+3
Explanation: Move the x to the other side by subtracting it from both sides, you end up with 10y=30-5x then you divide 10 from both sides and you end up with y=-.5x+3
