Answer:
Store 2 has a better deal with 0.233 cents per role
Step-by-step explanation:
If Store 1 has 12 Paper Rolls that cost $3.30 and Store 2 has 15 Paper Rolls that cost $3.50, we can find the answer by using division.
price/amount: 3.3/12=0.275 cents per role
price/amount: 3.5/15=0.233 cents per role
Order of Operation is commonly referred to as PEMDAS, an acronym for "Please excuse my dear aunt Sally," which references the order in which operations should be calculated when solving a math problem.
P = parentheses
E = exponent
M = multiply
D = divide
A = add
S = subtract
So you don't always have all of these components, but you consider the ones present in the problem in front of you. If there is no multiplication, but there is division and a set of parentheses, then you FIRST solve what's inside the parentheses, then you divide. If you have some examples, I'll show you.
Answer:
2nd Option: x + y = -1
General Formulas and Concepts:
<u>Pre-Algebra</u>
Order of Operations: BPEMDAS
- Brackets
- Parenthesis
- Exponents
- Multiplication
- Division
- Addition
- Subtraction
<u>Algebra I/Geometry</u>
- Plug 'n' Chug
- Graphing and Eyeballing
Step-by-step explanation:
Since Point A is included in the altitude, we must have an equation that has to make Point A a solution set in the equation.
Pluging in and chugging Point A into each equation should tell us what the equation should be.
<u>Option 1</u>
x - y = 1
-3 - 2 = 1
-5 ≠ 1
We see here that -5 does not equal to 1. Therefore option 1 is incorrect.
<u>Option 2</u>
x + y = -1
-3 + 2 = -1
-1 = -1
We see here that -1 does equal to -1. Therefore option 2 is correct.
<u>Option 3</u>
x + y = 1
-3 + 2 = 1
-1 ≠ 1
We see here that -1 does not equal to 1. Therefore option 3 is incorrect.
<u>Option 4</u>
x - y = -1
-3 - 2 = -1
-5 ≠ -1
We see here that -5 does not equal to 1. Therefore option 4 is incorrect.
We can also graph the points and eyeball it. Doing so, we should see that our y-intercept is around -1 and our slope is also negative. Option 2 would be the best fit.
