The answer is C. if you need the work I can give it to you
Answer: -3
Explanation: In this problem, we're given the function f(x) = 2x + 1 and we're asked to find f(-2).
To find f(-2) or the value of the function or the value of the function when <em>x = -2</em>, we simply substitute -2 in for <em>x</em> in our function.
So we have f(-2) = 2(-2) + 1 or -4 + 1 which equals -3.
So f(-2) or the value of the function when x = -3 is -3.
He can, if he subtracts the 1/10 from 10/10 or 1 he will have 9/10.. hope it helped
The system of equations that Sam can use is given by:
A 13b + 4t =327.50, 6b + 2t = 142.96
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
- Variable b: Cost of a bush.
- Variable t: Cost of a tree.
The first order was for 13 bushes and 4 trees, and totaled $327.50, hence:
13b + 4t = 327.50.
The second order was for 6 bushes and 2 trees, and totaled $142.96, hence:
6b + 2t = 142.96.
Which means that option A is correct.

Answer:
Robert earned $23 for each lawn that he mowed.
Step-by-step explanation:
Identify what you know:
1) Robert earned a total of $184 dollars for mowing 8 lawns
2) He was paid the same amount for mowing each of the eight lawns.
So, let's write our equations, where x equals the total that he was paid for one lawn.
$184/8 = x
OR
x times 8 = $184
We can reverse engineer both problems!
$184 divided by 8 = $23
