Answer:
![\boxed {\boxed {\sf A. \ 4x+1}}](https://tex.z-dn.net/?f=%5Cboxed%20%7B%5Cboxed%20%7B%5Csf%20A.%20%5C%204x%2B1%7D%7D)
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).
![(f+g)(x)=f(x)+g(x)](https://tex.z-dn.net/?f=%28f%2Bg%29%28x%29%3Df%28x%29%2Bg%28x%29)
We know that f(x) equals 3x-1 and g(x) equals x+2. Substitute the values of the functions in.
![(f+g)(x)=(3x-1)+(x+2)](https://tex.z-dn.net/?f=%28f%2Bg%29%28x%29%3D%283x-1%29%2B%28x%2B2%29)
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)=(3x+x)+(-1+2)](https://tex.z-dn.net/?f=%28f%2Bg%29%28x%29%3D%283x%2Bx%29%2B%28-1%2B2%29)
![(f+g)(x)=(4x)+(1)=4x+1](https://tex.z-dn.net/?f=%28f%2Bg%29%28x%29%3D%284x%29%2B%281%29%3D4x%2B1)
(f+g)(x) is equal to <u>4x+1</u> and the correct answer is A.
Answer:8.3 repeating
Step-by-step explanation
First, subtract 47 by 32.
Then, multiply that difference by 5/9.
For ex:
47-32=15
15 x 5/9=8.3333333 and so on
Answer:
Yes, no two ordered pairs in this list has the same second element.
Step-by-step explanation:
The function is a relation that associates to different elements
and
different elements
and ![y_2.](https://tex.z-dn.net/?f=y_2.)
Given K = {(-3, -3), (-4, -4), (-5, -5), (-6, -6)}
So,
Since different x have different image points y, this relation is the function. The correct answer is "Yes, no two ordered pairs in this list has the same second element."
Answer:
$3.75
Step-by-step explanation:
Given:
Natalie buys a cooper wire that is 3 feet long.
The cost of the wire is $1.25 per foot.
Question asked:
What is the total cost, in dollars, of Natalie's wire?
Solution:
<u>By unitary method:</u>
Total length of wire = 3 feet
Each foot of wire cost = $1.25
3 feet of wire cost = $1.25
3 = $3.75
Thus, total cost of wire is $3.75
