Determine which ordered pair satisfies the system of linear equation

1 answer:

6 0

(1/2,-1/2)

You have to plug in the x point into the equation and the solution to that must equal your y point the only one that works for this is (1/2,-1/2).

-1/2=3(1/2)-2
-1/2=3/2-2
-1/2=-1/2. Works

-1/2=-(1/2)
-1/2=-1/2. Works

Hope this helps!

lorasvet [3.4K]

Answer:

26 times

Step-by-step explanation:

Given

Without Coupon

$Rate = 1.75$ per trip

With Coupon

$Coupon = 26$

$Rate = 0.75$ per trip

Required

The number of trips to be taken for both option (i.e. with or without coupon) to be equal

See comment for complete question

Let the number of trips in a month be x.

Without Coupon

Total amount is:

$Total = Rate * x$

$Total = 1.75x$

Without Coupon

Total amount is:

$Total = Coupon + Rate * x$

$Total = 26 + 0.75x$

To get x, we simply equate both options

$1.75x = 26 + 0.75x$

Collect like terms

$-0.75x + 1.75x = 26$

$x = 26$
