Let's set it up like this:
Multiply both sides by
We are then going to use the distributive property. Since we also know that the opposite of an number that is squared is the square root, we can also apply that. We would be left with something like this:
The variable

Answer:
c
Step-by-step explanation:
From the graph as x gets larger and becomes positive f(x) approaches 0 so the answer is C.
Π=180⁰
-7π/2=(-7*180)/2=-7*90=-630⁰
-7π/2= -630⁰
Work out the second equation first.
7 + x= 5
-7 -7
x = -2
Plug in x.
3(-2)+2=?
-6+2=4
