Answer:
a=2
b=0
c=12
Step-by-step explanation:
The standard form of a quadratic equation is ax²+bx+c=0
Here's the given equation:
2x²+12=0
You might notice that the term bx is not there (there is just ax² and c). That means that b is 0.
The term 2x² is the term ax² in this equation. The coefficient in the term is 2, so that means that a is 2
12 has no variable, so that means it'll be c in the equation.

Factor out the coefficient of the variable -3.6m + 10.8
Answer: -1
Step-by-step explanation: First, factor out 3.6. You should get -m+3. Since the coefficient is just the number being multiplied to the variable (which is m here), your coefficient should be -1 because m is being multiplied to -1 to make -m. Hope this helps!

Write a system of equations to describe the situation below, solve using any method, and fill in the blanks.
Norma is looking for a job cutting hair. One option is self-employment at The Seaside Salon, where she would pay $534 per month to rent a station and keep all of her earnings. Another option is to work at a franchise, where she would just have to pay the salon $3 for every haircut. If she performed a certain number of haircuts every month, the amount paid to either salon would be the same. How many haircuts would that be? How much would Norma pay?
If Norma performed__________ haircuts in a month, she would pay $____________ to either salon.
Answer:
If Norma performed 178 haircuts in a month, she would pay $534 to either salon
Step-by-step explanation:
Saloon 1:
Cost of saloon 1 = $534
Saloon 2:
Cost of saloon 2 = 3h
Where,
h = number of haircut
Equate the cost of renting either saloon
534 = 3h
h = 534 / 3
h = 178 hair cut
If Norma performed 178 haircuts in a month, she would pay $534 to either salon.
