Answer:
-f(3x - 1) + 2 = -18x² + 12x + 1
Step-by-step explanation:
Step 1: Find f(3x - 1)
f(3x - 1) = 2(3x - 1)² - 1
f(3x - 1) = 2(9x² - 6x + 1) - 1
f(3x - 1) = 18x² - 12x + 2 - 1
f(3x - 1) = 18x² - 12x + 1
Step 2: Plug in f(3x - 1)
-(18x² - 12x + 1) + 2
Step 3: Evaluate
-18x² + 12x - 1 + 2
-f(3x - 1) + 2 = -18x² + 12x + 1
Would it be
(2r-7)*(2r+7)
?
Answer:
Here is a graph I created.
For Miguel to spend the least amount of money, he would have to buy 2 gallons for $5.98 and two 1/2 gallons for $4.20. The total is $10.18.
I'm stuck on the next question though.
Answer:
-3
Step-by-step explanation:
Slope is equal to (-5-7)/(2-(-2)=-12/4=-3
4=2c-12-4
4=2c-16
20=2c
10=c
