Answer:
C
Step-by-step explanation:
note that (f - g)(x) = f(x) - g(x)
f(x) - g(x)
= 10x + 7 - (x² - 7x) ← distribute parenthesis by - 1
= 10x + 7 - x² + 7x ← collect like terms
= - x² + 17x + 7 → C
Answer:
B
Step-by-step explanation
the answer is b, but check to make sure your question is in the correct category!
Answer: See below
Step-by-step explanation:
-5x<2 means -5x is less than 2, so a decimal under 0.4 (but not equal to) such as 0.3, 0.2, and 0.1 would all make the inequality true
Ex. Let x = 0.2
-5(0.2) < 2
1 < 2
1 is less than 2, so the inequality is true
Plug in 0 for x and you get 5. Which is your answer :)
