Answer:
Distributive Property of Multiplication
As we know the formula to calculate the slope is m = y2 - y1 divided by x2 - x1.
Where m is the slope. y2 is the second y co ordinate. y1 is the first y co ordinate. x2 is the second x co ordinate. x1 is the first x co ordinate.
So to calculate we can write it out as -7 = v - (-5) / 5 - 7, which further becomes -14 = v + 5 and v comes out to be -19.
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.
