Answer:
The answer is 25.
Step-by-step explanation:
What you have to do here is just replace "x" in the equation with -3. In other words, you plug in -3 to f(x).
f(-3) = 5(2 - - 3).
To negatives makes a positive.
f(-3) = 5(2 + 3).
f(-3) = 5(5).
5 times 5 is 25.
f(-3) = 25.
So your answer is 25.
75 degrees warmer.
If you subtract -39 by -114, you get 75 which is the distance between the two temperatures
You spent 9 dollars. why? because your neighbor spent 3 times more than you, which means you spent 1/3 of what he spent. so just multiply by 1/3 to get 9.
this can also be modeled by an equation. 3x = 27
divide 3 on both sides to get
x = 9
Not sure if you have an answer choice but with my guess distribute the sums and it should leave an expression of 8X+28
