Answer:
(0,3) and (0,11)
Step-by-step explanation:
A tip for next time is that if the "0" is first, then it is the y-axis. And if the "0" is second, it is the x-axis.
Use the slope formula.
m = slope = (y2 - y1)/(x2 - x1)
m = (4 - 1)/(0 - (-1)) = 3/1 = 3
Answer: 76Wh
Step-by-step explanation:
Basically all you have to do to find the answer is multiply 80 by 0.05. Then after that you subtract 80 by the answer you got. That's pretty much it.

Answer:
296.97
Step-by-step explanation:
Remark
The first thing you have to realize is that you take the discount before you add the sales tax.
Discount
If she receives a 15% discount, she still pays 85% of the full price.
85/100 * 325 = 276.25
Sales Tax
A sales tax is only added on after a goods or service has been determined and agreed upon by the buyer and seller.
The sales tax can be calculated quickly by adding the decimal equivalent onto 1 and multiplying that by the discounted amount.
1 + 7.5% = 1 + 7.5/100 = 1 + 0.075 = 1.075 deriving the discount amount
Cost
Cost = discounted price * 1.075 Substitute in Formula
Cost = 276.25 * 1.075 Simplify
Cost = 296.97 Answer
