Pls help me ASAP!!! Tickets for a concert cost $7.50 for students and $15 for adults. 150 ticket are sold, and $1612.50 is colle
mariarad [96]
Answer: 85 student tickets, 65 adult tickets.
Let's say the # of students is x and the # of adults is y. The two equations we get are 7.50x + 15y = 1612.50 and x + y = 150
x = 150 - y
7.5(150-y) + 15y = 1612.5
1125-7.5y+15y=1612.5
7.5y=487.5
y=65

x=150-65
x=85

Hope this helps!

Question 52 ptsWhat type of function is y - 5 = 5x? Explain.The function is linear because it can be written in the form y = mx
strojnjashka [21]

If a function can be written in y = mx + b form, it is linear.

The function given:

y-5=5x

Taking "5" to the right hand side, we get:

y=5x+5

This is in the form y = mx + b, with m = 5 and b = 5.

This is a linear function.
