B (-3, 3)... Hope this helps!!
Answer:
1: by using this equation x*y=96, or just list out 96's factors
2: 3 by 32
3: no, unless you want to use decimals.
4: finding the surface area
Answer:
Part 1
The mistake is Step 2: P + 2·x = 2·y
Part 2
The correct answer is
Step 2 correction: P - 2·x = 2·y
(P - 2·x)/2 = y
Step-by-step explanation:
Part 1
The student's steps are;
Step 1; P = 2·x + 2·y
Step 2: P + 2·x = 2·y
Step 3: P + 2·x/2 = y
The mistake in the work is in Step 2
The mistake is moving 2·x to the left hand side of the equation by adding 2·x to <em>P </em>to get; P + 2·x = 2·y
Part 2
To correct method to move 2·x to the left hand side of the equation, leaving only 2·y on the right hand side is to subtract 2·x from both sides of the equation as follows;
Step 2 correction: P - 2·x = 2·x + 2·y - 2·x = 2·x - 2·x + 2·y = 2·y
∴ P - 2·x = 2·y
(P - 2·x)/2 = y
y = (P - 2·x)/2
Answer:

Step-by-step explanation:

Divide the % of tax u want to leave by 100 then multiply that by the total. that will give u the $ of tax. if u add that on to the sub total that will give u the final total.
Example:
18/100= .18
.18x$23.50= $4.23 (this is the tax in $
$23.50+$4.23= $27.73
