Answer: 10x - 15y because 5(2x) = 10x and 5(-3y) = -15y
Answer:
y = 2x – 13
Step-by-step explanation:
Use Slope formula to get the slope
(y2-y1) / (x2-x1)
(-7--1) / (3-6)
(-6)/(-3)
2
Then plug-in the value of slope and any one coordinate in Point-Slope formula:
y- y1= m(x-x1)
y - -1 = 2( x - 6)
y + 1 = 2x - 12
y = 2x - 13
s = the number of student tickets sold
a = the number of adult tickets sold
The drama class sold 25 more student tickets than adult tickets to the fall play
s = a + 25
The class collected $660 from ticket sales:
6s + 3a = 660 divide both sides by 3
2s + a = 220
by solving the system of equations
s = a + 25
2s + a = 220
we find
s = 81.67 student tickets
a = 56.67 adult tickets
