If f(x)= -4x + 3 and g(x) = 3x² + 2x - 4 find (f+g)(x)
pychu [463]

Answer:

A

Step-by-step explanation:

We have the two functions:

f(x)=-4x+3\text{ and } g(x)=3x^2+2x-4

And we want to find (f+g)(x).

Note that this is the same thing to f(x)+g(x). Therefore:

\begin{aligned} (f+g)(x)&=f(x)+g(x) \\ &=(-4x+3)+(3x^2+2x-4) \end{aligned}

We simply substituted them for their equations.

Simplify. Combine like terms:

=(3x^2)+(-4x+2x)+(3-4)

Add:

=3x^2-2x-1

Hence, our answer is A.

Find the value of 7u+2 given that -2u+8=6
Natasha2012 [34]

Answer:

The value of 7u + 2 is 9.

Step-by-step explanation:

To solve this problem, we first must find the value of u given the second equation.  The first step in simplifying this equation is to subtract 8 from both sides of the equation.  This is modeled below:

-2u + 8 = 6

-2u + 8 - 8 = 6 -8

-2u = -2

Next, we can divide both sides by -2 to get the variable u alone on the left side of the equation.

-2u/-2 = -2/-2

u = 1

Therefore, the correct answer is u = 1. Now, we can plug in this value for u into the expression that is given.

7u + 2

= 7(1) + 2

= 9

Thus, the correct answer is 9.

Hope this helps!
