Answer:
a = 14
Step-by-step explanation:
<u>Step 1: Write out your problem</u>
f (a) = 5a + 14 | f (a) = 0
<u>Step 2: Solve</u>
f (a) = 5 (0) + 14 , Input a.
f (a) = 0 + 14 , 5 x 0 = 0
(a) = 14 , 0 + 14
a = 14
Answer:
acute
Step-by-step explanation:
Answer:
V
Step-by-step explanation:
The point in the question is U
When reflected in the x-axis, it becomes W
When W is reflected in the y-axis, it becomes V
Let M = #miles driven
Plan 1: .50M + 70 = total cost
Plan 2 .70M = total cost
To know how far she would drive to have an equal cost for either plan just set the equations equal to each other
.70M = .50M + 70
subtract .50M from both sides
.20M = 70
M = 70/.20 = 350 miles
Check the answser:
Plan 1: .50(350) + 70 = 175 + 70 = $245
Plan 2: .7(350) = $245
they are equal so our answer checks as correct
