Answers:
1A. You see, every amount of T shirts costs 5.5 times more than it's amount. So if "n" is the number of shirts and "C" is what it costs, then the equation must be C=5.5n.
1B. Idon't know how to graph it here sorry.
1C. You have to look back to the equation. It has our coefficient (5.5n) on one side and C on the other,so the answer is just 5.5n. Now the questions says 120 shirts so (120)5.5 equals 660.
1D. I just did
Answer:
D
Step-by-step explanation:
The expression is 
We can follow the rule of "PEMDAS" here.
PEMDAS = Parenthesis, Exponents, Multiply, Divide, Add, Subtract
So, we first need to deal with Parenthesis. Next,
There aren't any exponents, so we deal with Multiplication of 7 and 3.
Then addition/subtraction.
Hence, the first step, from the answer choices, would be D, multiply 7 and 3
Answer:
f(3) = 16
Step-by-step explanation:
f(x)= 7x-5
We want to find the value when x=3
f(3) = 7*3 -5
f(3) = 21-5
f(3) = 16
