1 answer:
Anastasy [175]3 years ago
4 0

Answer:

x=2/5, y=-3. (2/5, -3).

Step-by-step explanation:

10x+3y=-5

-5x-4y=10

----------------

10x+3y=-5

2(-5x-4y)=2(10)

-------------------------

10x+3y=-5

-10x-8y=20

-------------------

-5y=15

y=15/-5

y=-3

10x+3(-3)=-5

10x-9=-5

10x=-5+9

10x=4

x=4/10=2/5

Afan pays $875 for 3 premium seat tickets. Another fan pays $2125 for 8 premium seat tickets. Write a linear model for the cost
grandymaker [24]

The equation is : C=250t +125 where C is the cost and t represent the number of tickets purchased.

Step-by-step explanation:

Let the cost of premium seat ticket be C

Let the number of tickets a fan buys to be t

Then, presenting the information as ordered pairs of coordinates (x,y) will be;

Fan 1, (3,875)

Fan 2, (8,2125)

Plot the ordered pairs as coordinates on a graph tool, find the slope of the linear graph and equation in slope intercept form as;

m=Δy/Δx

m=2125-875/8-3

m=1250/5

m=250

Equation of the graph,

Δy/Δx=250

y-875/x-3 =250

y-875=250(x-3)

y-875=250x-750

y=250x-750+875

y=250x+125

C=250t +125 where C is the cost and t represent the number of tickets purchased
