Answer:
Step-by-step explanation:
<u>Let's check his work by simplifying the given expression.</u>
- 2(x - 2) - 2(3)
- => 2x - 4 - 6
- => 2x - 10
When I compare Marty's result and this result, they are un-equal. Hence, Marty is incorrect.
<u>Marty's mistake</u>
- Marty must've got the problem wrong because of not understanding the distributive property.
- He probably forgot to multiply -2 by 2. Instead, he only subtracted 2 when he should've subtracted 4 from 2x.
Answer:
c = 7
Step-by-step explanation:
Given
2x + y = c
Since (3, 1) is on the line then it makes the equation true,
Substitute x = 3, y = 1 into the equation
2(3) + 1 = c
6 + 1 = c
7 = c
I don’t think functions can have repeating x values
Answer:
Step-by-step explanation:
You're trying to solve
for a, right?
When you have a fraction set equal to a fraction, you can cross multiply to get rid of the fractions. That would mean that
ap = mn. Solving for a means that you divide both sides by p:
