Answer:
It is the y=intercept
Step-by-step explanation:
Because if there is no x-value and there is a Y-value, y-intercept
Answer:
x + y = 32
x = y + 8
Step-by-step explanation:
Sum of two numbers is 32:
x + y = 32
One number is 8 more than the other:
x = y + 8
Let's say the cost of student tickets is x and the cost of adult tickets is y. Then:
(1) 12y + 6x = 138
(2) 5y + 11x = 100
If we rearrange equation (1) we get:
12y = 138 - 6x
Now divide each side by 12:
y = 11.5 - 0.5x
We can now substitute this into equation (2):
5(11.5 - 0.5x) + 11x = 100
57.5 - 2.5x + 11x = 100
8.5x = 42.5
x = 5, therefor the cost of a student ticket is $5.00
