If f(x) = (3x + 7)²
then f(1) = (3(1) + 7)²
= 10²
⇒ f(1) = 100 [OPTION E]
Yes your correct tttttttttttttttttttttttttttttttttttttttttttttttttttttttttt
Answer:
slope = 5
Step-by-step explanation:
Parallel lines have the same slope
Equation: y = mx + b
So, slope m = 5
To find the amount of miles/gallon, we have 540 miles/18 gallons=30 miles/gallon. As we add 30 miles for every gallon, the amount of miles traveled is 30*x (e.g. if x is 1 then 0+30=30 and if x is 2 then 30+30 (2 times)=60) with x being the amount of gallons. For b, we just plug 12 in for x to get 20*12=360
