Answer & Step-by-step explanation:
In this problem, we are given two functions.
<em>s(x) = 2x + 1</em>
<em>r(x) = -x² + 3x</em>
We are asked to find the difference between s(x) and r(x).
<em>(2x + 1) - (-x² + 3x)</em>
Distribute the negative to the second parentheses.
<em>2x + 1 + x² - 3x</em>
Combine like terms and put the equation in standard form. This means the exponents should be in descending order.
<em>x² - x + 1</em>
So, (s - r)(x) equals x² - x + 1

Answer:45
Step-by-step explanation:
Divide each term in
5
So, in this problem you already have the equations set up for how much money each one works. You have Jim, earning a starting amount of $35, plus an additional $3 for every hour he works. You also have John, who gets $8.
The variable in the equations is h, which stands for hours. From there, you can put the three different h values (6, 7, and 8) into the equations to see who gets more money.
For instance, for Day 1, Jim gets 35+3x6 dollars, or 35+18=$53, while John gets 8x6 dollars, or $48. You can substitute in 7 and 8 and do the same process to get the answers for Day 1 and 2.
Hope this helps!
