Answer:
<h2>f(x) = 3x + 4</h2>
Step-by-step explanation:
f(x + 1) = 3x - 7
f(x) = f(x + 1 - 1) = 3(x - 1) + 7 = 3x - 3 + 7 = 3x + 4
Check
f(x) = 3x + 4
f(x + 1) = 3(x + 1) + 4 = 3x + 3 + 4 = 3x + 7 CORRECT
When Jamie has $200 to purchase skateboard equipment, he will have spent more than 50 percent.
<h3>How to calculate the percentage?</h3>
From the information given, the total amount spent will be:
= $100 + $60 + $30 + $20 + $20 + $50 + $115
= $395
Since Jamie has $200 to purchase skateboard equipment, the percentage will be:
= 200/395
= 0.51
= 51%

Answer:
[6x] + [-7y] + [-4]
Step-by-step explanation:
There are only two like terms in this expression "4x" and "2x." Since they are like terms we can combine them by adding the coefficients and keeping the variable attached. Therefore we can combine 4x and 2x into 6x. Since there are no more like terms, this expression can be simplified to 6x - 7y - 4.
The answer would be C. 72
Jenna is correct. This is because the square root of 2 is an irrational number. And if the number is a prime number, the answer is less likely to have a rational square root.
