(f+g)(x) is 3x^2 + 3x/2 - 9
(f+g)(x)=f(x)+g(x)=x/2-3+3x^2+x-6= 3x^2 + 3x/2- 9
Answer:
The angles are complementary angles
Step-by-step explanation:
Given that a triangle has three sides and three angles
From the above question the unknown side of the triangle has a fixed value ( given ) hence the two angles adjacent to the unknown side will be <em>complementary angles</em>. this is because the sum of the angles of a triangle = 180°
Hello from MrBillDoesMath!
Answer: line EF
Discussion: Two lines, L1 and L2, with slopes m1 and m2 are perpendicular if
m1 * m2 = -1. In our case m1 = -1/3 so the slope of the perpendicular line is 3.
( 3 * (-1/3) = -1). The line with slope 3 is rising as x gets larger. The only line shown fitting this is line EF. Note that line AB is "falling" as x increases so it can not possibly be the answer.

A + (-5) = -12
First isolate your variable so move the -5 over (by adding 5 to both sides)
Then you will have a = -12+5
Simplify and you get A= -7
