10 1/2
10.5 = 10 5/10
but 5/10 can be simplified to 1/2
the answer is 10 1/2
We can use the points (-4, -1) and (-8, 7) to solve.
Slope formula: y2-y1/x2-x1
= 7-(-1)/-8-(-4)
= 8/-4
= -2
Find the y-intercept.
y = 2x + b
-1 = 2(-4) + b
-1 = -8 + b
-1 + 8 = -8 + b + 8
7 = b
Now, put in slope-intercept form.
y = -2x + 7

Let a and c represent the numbers of adult and children's tickets sold, respectively. The system of equations will have one equation for revenue and one equation for number of tickets.
The revenue equation is
18a +9c = 4959
The number of tickets equation is
a + c = 319
_____
The solution can be found any number of ways. It is
(a, c) = (232, 87)
Answer:
If the sum of the digits of a number is divisible by 9, then that number is divisible by 9. An..... sorry if this does not help :(
Step-by-step explanation:
The answer is 4 for both x and y
6 • 4 = 24
12 • 4 = 48
24 - 48 + 24 = 0
-24 + 24 = 0
-24 - (-24) = 0
