Answer:
Answer Option C
Step-by-step explanation:
They make a big plus sign, PLUS=PERPENDICULAR
(f+g)(x)=f(x)+g(x)=(2x-6)+(4x+7)=6x+1
(f-g)(x)=f(x)-g(x)=(2x-6)-(4x+7)=-2x-13
(fg)(x)=f(x)×g(x)=(2x-6)(4x+7)=8x^2-10x-42
(f+g)(-2)=f(-2)+g(-2)=(2(-2)-6)+(4(-2)+7)=-11
Answer:
x = 24
Step-by-step explanation:
The sum of the measures of the angles of a triangle is 180°.
4x + x + 60 = 180
5x + 60 = 180
5x = 120
x = 24
Answer:
C. infinite
Step-by-step explanation:
Both of the equations overlap so there are infinite solutions to the system of equations.

Answer:
y=-3x+b
Step-by-step explanation:
To find whether or not an equation is parallel it has to have the same slope. To find this, you start by subtracting 9x from both sides, leaving you with 3y=-9x-22. Then you divide both sides by 3, leaving y=-3x-
. With this equation you can see that the slope is -3. The answer will be any equation with -3x.
