The answer to the question is c
Paralell is smae slope so it is
2x+3y=c
find c
given
(9,-3)
x=9
y=-3
evaluate to find the constant, c
2(9)+3(-3)=c
18-9=c
9=c
the equation is 2x+3y=9
Answer:
One adult ticket is $4 and one child ticket is $7
Step-by-step explanation:
Make a system of equations
2x + 10y = 78
8x + 5y = 67
Solve by elimination, multiply the 2nd equation by -2
2x +10y = 78
-16x -10y = -134
Add the equations
-14x = -56
x = 4
The price of one adult ticket is $4
Plug 4 in as x to find y
2(4) + 10y = 78
8 + 10y = 78
10y = 70
y = 7
The price of one child ticket is $7
Answer:A
Step-by-step explanation:
Answer: 103 degrees
Step-by-step explanation: all angle of a regular triangle always add up to 180. so 62+15=77. and 180 - 77= 103
