Give the equation of a parallel line to x=3 going thru (2,5)

y=3x+5

Step-by-step explanation:

The formula is y=mx +b if m is the slope then 3 goes there. If b is the y intercept then 5 goes there since (x,y)

$20.5

Step-by-step explanation:

Let x  denotes the amount for total bill.

We are given that ,  Sierra left $4.50 as a tip for a waiter.

This was 18% of the bill before the tip.

We can write 18% = 0.18. [To convert percent into decimal we divide it by 100.]

Then, the tip amount = 0.18 x Total bill

So, the total bill amount = $25

Hence, her total bill before the tip= Total bill amount - Tip amount

= $25- $4.50=$20.5

Thus ,her total bill before the tip= $20.5
