Answer:
f(7) = 16
Step-by-step explanation:
substitute x = 7 into f(x) , that is
f(7) = 3(7) - 5 = 21 - 5 = 16
Answer:
-1, 2
Step-by-step explanation:
Multiply 12 x 12 which is 144. And then you divide that by 6 and you get 24
-20 * 3 / -30 / 3
First multiply the top and divide the bottom to simplify the problem:
-20 * 3 = -60
-30/3 = -10
Now you have -60 / -10
Divide:
-60 / -10 = 6
The equation you have to solve is 1.50 + (0.75 • 6). First, you solve what is in the parenthesis, 0.75 • 6 = 4.50. Now you simply add 1.50 and 4.50 to get $6, the total cost for 7 hours worth of parking.
