Answer:
(1 , 3)
Step-by-step explanation:
→ Make equations equal to each other
2x + 1 = 4x - 1
→ Solve
-2x = -2
→ Divide by 2 on both sides
x = 1
→ Substitute x = 1 into the y = 2x + 1
2 × 1 + 1 = 3
Answer:
C = $5.25g + $45.50
Step-by-step explanation:
The $45.50 is her monthly bill and does not change. The additional fee determines on the amount of gigabytes she used which is undetermined, using the variable g. It cost $5.25 per gigabyte. C is her total/the bill.
For this case we have the following equation:
To solve we follow the steps below:
We add similar terms from the left side of the equation:
We divide between 6 on both sides of the equation:
Finally, we have to:
Answer:
(0,0) represents the very beginning of the rental period: 0 time has elapsed, and thus there is no charge.
(1,125) represents this situation 1 hour after the rental has begun, and shows that the amount due at that point for the rental is
$125.
The answer is 223.75 because you multiply 12.5 and 17.9
