Answer: y = x^2 - 11x + 24
Step-by-step explanation:
The answer is D. 50 because x equals 7 so if you fill that in for 4x-3 and multiply it by 2, you get 50
C. $34.50. A car gets 30 miles per gallon, if the gasoline cost $1.15 per gallon, a 900 miles trip will cost $34.50
This exercise can be solved by simply arithmetic.
Divide the total miles by the miles per gallon:
900/30 = 30
Then, multiply this value by the cost per gallon:
30 x $1.15 = $34.50
