You have the correct answer. The answer is choice D) Set of real numbers less than -1. Nice job. 

As x approaches negative infinity, then -3^x approaches 0 though never actually gets there. So overall, f(x) approaches -1 as x approaches negative infinity. Plugging in x = 0 leads to f(x) = -2 which supports choice D.

lianna [129]

Answer:

Y=-3/2

Step-by-step explanation:

-2y+3=-4y

Move constant to the right  by adding its opposite to both sides

-2y+3-3=-4y-3

Eliminate the opposites

-2y=-4y-3

collect the like terms

-2y+4y

collect the like terms

(-2+4)y

Calculate the sum

2y=-3

divide both sides of the equation by 2

2y÷2=-3÷2

Any expression divided by itself equal 1

y=-3÷2

y=-3/2

Which expression is equivalent to 6m + (m – 2)(m + 7) + 3?
LuckyWell [14K]

Hello from MrBillDoesMath!

Answer:

m^2 + 11m - 11, which is the first choice


Discussion:

6m +  (m-2)(m+7) +3 =

6m  + (m^2 + 7m - 2m -14) + 3 =

(6m + 7m - 2m) + m^2 + (-14 + 3) =             combine similar terms

11m + m^2 -11 =

m^2 + 11m - 11


which is the first choice


Thank you,
