Answer:
2 1
8 4
10 5
Step-by-step explanation:
We already know that it takes 8 lemons to make 4 cups of lemonade. So, to get the number of lemons needed to make 1 cup of lemonade, we divide the lemons and cups by 4.
8 divided by 4 = 2 and 4 divided by 4 = 1. Therefore, it takes 2 lemons to make 1 cup of lemonade.
By this logic, to figure how many cups are needed for 10 lemons, and since we know 2 lemons = 1 cup of lemonade, we multiply the lemons and cups by 5. 2 times 5 is 10 (lemons) and 1 times 5 is 5 (cups). Therefore, 10 lemons are needed to make 5 cups of lemonade.
To plot this on the coordinate axes, the first point goes (2,1) second being (8,4) and third point being (10,5).
side note - is this delta math? I feel your pain
Answer:

General Formulas and Concepts:
<u>Algebra I</u>
- Terms/Coefficients
- Factoring
- Solving quadratics
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
f(x) = x² - x - 12
<u>Step 2: Solve for </u><em><u>x</u></em>
- Factor: (x - 4)(x + 3) = 0
- Solve: x = 4, -3
What is the rest of the question?
You’re trying to get the first equation to equal y so you can substitute it in the second question
2x + y = -2
subtract 2x from both sides: y = -2 - 2x
rearrange the equation : -2x -2
so the answer is C
