Problem 18
The x should not be in the denominator. If it was in the denominator, then you wouldn't have a linear equation in the form y = mx+b
Instead, you should have written or y = (1/17)x + 63/17
Comparing that to y = mx+b form, we see that m = 1/17 is the slope and b = 63/17 is the y intercept.
============================================
Problem 19
This problem isn't fully shown. The right portion is cut off. I have a feeling the same issue is happening here though. Try moving the x term like mentioned in problem 18. Also, don't forget about the "y=" portion.
Answer:
The price will be $105.47
Step-by-step explanation:
Given that i purchase a product for $79.99 and two accessories for $9.99 and $7.00. we have to find how much will i owe after taxes applies 8.75%
Now, the cost price of the product and the two accessories will be
$79.99+$9.99+$7.00
= $96.98
Now, also the tax applies at the rate 8.75%
∴
=
Hence, the price which i owe after taxes will be $96.98+$8.49=$105.47
