Answer:
a) Here x represent number of ride tickets
z represent admission fees. = $20
y represent total cost.
Step-by-step explanation:
a) Here x represent number of ride tickets
z represent admission fees.
y represent total cost.
b) Given that,
$0.75 per ticket for the rides.
Number of tickets (x) = 18
Total spent (y) = $33.50
Total cost = (number of tickets)*(price per ticket) + admission fees
y =0.75x + a
We can calculate the cost for anyone who only pays for festival admission and rides.
c)
Put y = 33.50
x = 18
33.50 = 0.75*18 + a
33.50 = 13.5 + a
Solve for a,
Subtract 13.50 both the side
33.50 - 13.50 = 13.50-13.50 + a
20 = a
So, admission cost (a) = $20

Answer: A
Step-by-step explanation:
Answer:
17. y=1/2x+5
18. y=-2x+15
19. y=2x-7
Step-by-step explanation:
Number 17.
(4,7); parallel to y=1/2x-1
You know that lines that are parallel to each other have the same slope, so the slope is 1/2x.
1. Use the point-slope formula to solve for the slope-intercept equation.
y-y1=m(x-x1)
m= 1/2
x= 4
y= 7
y-7= 1/2(x-4)
y-7= 1/2x-2
y=1/2x+5
Number 18.
(4,7); perpendicular to y=1/2x-1
You know that lines that are perpendicular to each other have the opposite reciprocal slope, so the slope is -2.
1. Use the point-slope formula to solve for the slope-intercept equation.
y-y1=m(x-x1)
m= -2
x= 4
y= 7
y-7=-2(x-4)
y-7=-2x+8
y=-2x+15
Number 19.
f(3)=-1
f(4)=1
To write a linear equation, first find the slope with the slope formula.
x1= 3
y1= -1
x2= 4
y2=1
(y2-y1)/(x2-x1)
(1-(-1))/(4-3)
2/1
m=2
Use the point-slope formula and solve for the slope-intercept equation.
y-y1=m(x-x1)
y-1=2(x-4)
y-1=2x-8
y=2x-7
