Answer: C. g(-2) = -5
<u>Step-by-step explanation:</u>
g(-2) is when you replace all of the x's in the function with -2
g(x) = -3x² - 2x + 3
g(-2) = -3(-2)² - 2(-2) + 3
= -3(4) + 4 + 3
= - 12 + 4 + 3
= -12 +7
= -5
Answer:
Yes, he can buy 8 donuts and 4 energy drinks.
Step-by-step explanation:
If Tension is able to buy 8 donuts and 4 energy drinks, then both inequalities would be valid when we use these numbers as inputs. Let's check each expression at a time:

The first one is valid, since 14 is less than 25. Let's check the second one.

The second one is also valid.
Since both expressions are valid, Tension can buy 8 donuts and 4 energy drinks and achieve his goal of having a caloric surplus of at least 1000 cal.
X= original $
Original $ - % of original $= total $
x - 15%x= $22.10
x- 0.15= 22.10
Combine like terms
0.85x= 22.10
Divide both sides by 0.85
x= $26 original price
Hope this helps! :)
