Answer:
8 child tickets and 4 adult tickets.
Step-by-step explanation:
8c + 11a = 108
8x + 11y = 108
Lets graph it.
When we graph, we find that there it crosses at 2 whole numbers: (8, 4).
So there were 8 child tickets and 4 adult tickets.
We can check our work by doing 8(8) + 4(11) = 108
We find that this is true, so our answer is correct.
Answer:
Step-by-step explanation:
For a parabolic equation to NOT contain the point (0,0) it must have a numeric constant independent from both x and y variables, so the general form would be as follows:
Solving the equation for the point (1,1) would give the necessary value for the constant "c" to make the equation valid:
Therefore, the equation that meets both of the required conditions is:
X - y = 5
x = y + 5
y = x - 5
