Answer:
Step-by-step explanation:
We are asked to find (f+g)(x). The question is essentially asking us to find the sum of f(x) and g(x).
We know that f(x) equals 3x-1 and g(x) equals x+2. Substitute the values of the functions in.
Combine the like terms.
- 3x and x are like terms (both have the variable "x"
- -1 and 2 are like terms (both without variables, also known as constants)
(f+g)(x) is equal to <u>4x+1</u> and the correct answer is A.

Answer:
The answer for y=2x-4 would be...x=1/2y+2
Step-by-step explanation:
Step 1: Flip the equation.
2x-4=y
Step 2: Add 4 to both sides.
2x-4+4=y+4
2x=y+4
Step 3: Divide both sides by 2.
2x/2=y+4/2
<u>x=1/2y+2</u>
y - 6 = - 5 * x - 5 * (-3)
y - 6 = -5x + 15
y + 5x = 15 + 6
5x + y = 21
Answer:
X-19
Step-by-step explanation:
First you need to distribute the three into the numbers in the parenthesis,
(3 * x) + (3 * -5) - (2x + 4)
That then turns into,
3x - 15 - (2x + 4)
but we aren't done distributing yet, because the second set of parenthesis has a negative sign in front of it we also have to distribute that. (this is because the negative sign is really just -1)
3x - 15 + (-1 * 2x) + (-1 * 4)
that turns into,
3x - 15 - 2x -4
from here all we have to do is add like terms,
(3x - 2x) + (-15 + -4)
and that leaves us with: 1x -19 or x-19
Hope that helped :))
