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!

Find the interest on the loan if you borrowed $2,000 at 8% for 1 year.
kodGreya [7K]
Future Value = Present Value*(1 + interest rate)^(# of years)

Future Value = $2,000(1+0.08)^1

Future Value = $2,000(1.08) = $2,160

To find the interest on the loan, we need to do our Future Value - Present Value.

Future Value - Present Value = $2,160 - $2,000 = $160

What is the equation of a line that contains the points (2,-2) and (0, -2)?
balu736 [363]

Answer:

y = - 2

Step-by-step explanation:

The equation of a horizontal line parallel to the x- axis is

y = c

where c is the value of the y- coordinates the line passes through.

The points (2, - 2) and (0, - 2) have the same y- coordinate and therefore lie on a horizontal line with equation

y = - 2

I’m still trying to do my work and trying to figure out this
swat32
The slope of a vertical line is undefined, D.

If you were to try to solve use something like the rise over run method, you would end up with a 0 in the denominator. Since dividing by 0 gives you an undefined result, the slope would be undefined.

The graph shows the amount of money paid when purchasing bags of peanuts at the zoo:
abruzzese [7]

Answer:

dive the cost by the number of bags for each dot:

4 / 1 = 4

8 / 2 = 4

12 / 3 = 4

This means each bag cost $4

The equation would be Y = 4X, because you would multiply each bag bought (X) by $4 to get the total cost (Y).
