The answer is $94.40 because he paid 9.44 in sales tax and you need to multiply that by 10 since sales tax is 10%. So, you will get a result of $94.40. You could also check this by multiplying 94.40 by 0.10 and if you get 9.44 (which you do) then it is correct.
Answer:
G(f(x)) = A. 3x + 7
Step-by-step explanation:
Plug F(x) into the x on G. so (3x+2) +5 = 3x+7
Hi there!

We are given the equation:
x² - 2y = 7
To verify if each ordered pair is apart of the function, we can plug in their respective x and y values:
1. (5)² - 2(8) = 7
25 - 16 = 9 ≠ 7. This is NOT correct.
2. (-1)² - 2(-3) = 7
1 + 6 = 7. This is correct.
3. (-4)² - 2(-11.5) = 7
16 + 23 = 39 ≠ 7. This is NOT correct.
4. (1.2)² - 2(-2.78) = 7
1.44 +5.56 = 7. This is correct.
Thus, only 1 and 4 are the correct answers.
