We can find 3 points by plugging them in
x = -12 y = 1
x = 10 y = 0
x = 0 y = 5
Answer:
D) 11
Step-by-step explanation:
If you start at five and count back on each little x
than you should come up with 11
0=3
1=1
2=2
3=4
4=1
3+1+2+4+1=11
You do This because you need to find how many has fewer so you don't count 5
Answer:
D=(-2,-8)
Step-by-step explanation:
the x coordinate of point c is located farther on the right side than the midpoint by four, therefore point D must be 4 to the left from the midpoint to keep the same distance.
2-4=-2
the same thing goes for the y coordinate. C is located 5 higher than the midpoint, therefore point D has to be located 5 lower than it.
-3-5=-8
The answer is C I just finished taking the test
Answer:
- adult tickets: $13
- student tickets $7
Step-by-step explanation:
The given equations are ...
4a +5s = 87
2a +2s = 40
We observe that the coefficient of 'a' in the first equation is 2 times that in the second equation. We can multiply the second equation by -2 and add it to the first to eliminate 'a' terms.
(4a +5s) -2(2a +2s) = (87) -2(40)
4a +5s -4a -4s = 87 -80 . . . . . . . . . eliminate parentheses
s = 7 . . . . . . . . . . . . . . . . . .simplify
2a +2(7) = 40 . . . substitute for s in the second equation
2a = 26 . . . . . . subtract 14
a = 13 . . . . . . . divide by 2
Adult tickets cost $13; student tickets cost $7.
