F(x) = 2x²+3x
g(x)= x-2
f(x)+ g(x) =( 2x²+3x ) +(x-2)
= 2x²+3x+x-2
= 2x²+4x-2
(f+g)(2) = 2(2)²+4(2)-2
= 2•4+8-2
= 8+8-2
= 14
hope to helped
The answer is <FGI and <HGD
7 < n, what you do is take the number figure out whether or not its bigger or smaller, add in the sign, and put your n or variable (:
Get unknowns on one side and know on other side.
Divide both sides by -2
X= -7
<u>Answer:</u>
The correct answer option is D. 120°, 240°.
<u>Step-by-step explanation:</u>
We are given the information about x that
.
We know that [tex]cos x=-\frac{1}{2}[/tex ] is actually the ratio of adjacent side to the hypotenuse. It means that here, adjacent is -1 and hypotenuse is 2.
A negative cosine tells us that the angle is either in Quadrant II or Quadrant III.
So if it is in 2nd quadrant, then x = 120° and if its in 3rd quadrant then x = 240°.
