Since he gets 10$ per shirt, his revenue is 10y if y represents the shirts sold as he adds 10$ with every purchase. His expenses start with the base cost of 1500, then he also has to pay 3 dollars for each shirt, so his expenses add up to 1500+3y. Since he wants to make as much as he spent, his revenue has to equal his expenses and 10y=1500+3y. Subtracting 3y from both sides, we get 7y=1500. Dividing both sides by 7, we get y=214.something=215 by rounding up
Answer:
4
Step-by-step explanation:
15/3.50 = 4.285
You need to round down to have the answer make sense (you can't buy 1/4 of a juice.

Answer:
83 degrees
Step-by-step explanation:
Supplementary angles are two angles whose sums add up to 180 degrees. Since you have one angle that is 97 degrees and one that is unknown, you can just subtract 97 from 180.
180 - 97 = 83 degrees
The answer to the questions
Answer:
The vertex form is: y = 3(x-2)^2 + 7
. The vertex is (2, 7)
Step-by-step explanation:
Write the function: y = 3x^2 - 12x + 11 in vertex form
The vertex form of a quadratic equation is:
y = m(x - a)^2 + b where (a,b) is the vertex
For y = 3x^2 - 12x + 11
Solve for m
y = 3(x^2 - 4x) + 11
Complete the Square:
y = 3(x^2 - 4x + 4) + 11 - 4
y = 3(x - 2)^2 + 7
The vertex then is (2, 7)
