Answer:
Youth tickets = $4
Step-by-step explanation:
Let x and y represent the price of adults and youth tickets respectively;
Given;
A youth ticket is half the price of an adult ticket
y = 0.5x ......1
They paid $24 for 2 adult tickets and 2 youth tickets.
2y + 2x = 24 ......2
Substituting equation 1 into 2;
2(0.5x) + 2x = 24
x + 2x = 24
3x = 25
x = 24/3 = 8
Since, y = 0.5x
y = 0.5(8) = 4
Adult tickets = $8
Youth tickets = $4
For this case we have that by definition, the equation of a line in the slope-intersection form is given by:
Where:
m: Is the slope
b: Is the cut-off point with the y axis
According to the data of the statement we have two points through which the line passes:
We found the slope:
Thus, the equation is of the form:
We substitute one of the points and find "b":
Finally, the equation is:
Answer:
Answer:
x = 3
y = -1
Step-by-step explanation:
Finding X
Substitute y into the 1st equation
3x + 2(x-8) = 7
Simplify
3x + 2x-8 = 7
Combine like terms
5x - 8 = 7
Move the constant (-8) to the right
5x = 7+ 8
Simplify
5x = 15
Divide both sides by 5
x = 3
Finding Y
Now since you know x is 3 substitute that into the 2nd equation
y = 3 - 4
y = -1
