Step-by-step explanation:
Answer:
Adult ticket = $11
Children ticket = $9
Step-by-step explanation:
Let the price of adult tickets be x and let the price of children's ticket be y
For the first day, the equation of sales can be put as
3x + 12y = 141..........1
For the second day, the equation of sales can be put as:
13x + 6y = 197............2
We then take these two equations together and solve simultaneously.
3x + 12y = 141.......1
13x + 6y = 197........2
Solving by elimination method, we Multiply through equation 1 by 13 and multiply through equation 2 by 3.
39x + 156y = 1833.........3
39x + 18y = 591..............4
Then subtract equation 4 from equation 3
138y =1242
y = 9
Substitute "y=9" into equation 1 to find x
3x + 12(9) =141
3x + 108 = 141
3x = 141 - 108
3x = 33
x = 11
Hence,
Price of adult ticket = $11
Price of children ticket = $9
A if 8 and 12 are legs the missing side would be 14.42
B if 8 is a leg and 12 is hypotenuse then the other leg would be 8.94
Answer:
Step-by-step explanation:in standard form y= ax+b
-4y = -3x+28
4y =3x-28
or y= 3/4 x -7
So a= 3/4 = slope and -7 is y intercept ( parallel lines have same slope)
Equation 3 is
y= 3/4x-2
which also has slope = 3/4 and y intercept = -2
Parallel lines have same slope
Similarly a perpendicular line will have slope of - 1/a
For equation
y= ax+b
Perpendicular line is
y=( -1/a) x +c
