3x+y+z=4 2x+2y+3z=3 X+3y+2z=5

zhenek [66]

1) 3x+y+z=4
2) 2x+2y+3z=3
3) x+3y+2z = 5

1)*2 6x + 2y + 2z = 8
2) 2x + 2y +3z = 3
- __________________
4x - z = 5

2)*3 6x + 6y + 9z = 9
3)*2 2x + 6y + 4z = 10
- __________________
4x+5z =-1

4x+5z = -1
4x - z =5
- ________
6z = -6
z = -1

If z=-1,

4x -(-1) =5
4x = 5-1
x = 4/4
x=1

3x+y+z=4
3(1)+y+(-1)=4
3+y-1=4
y=2

So z=-1, x=1, y=2

Taxi company charges $ 8.00 to get into the cab and $ 0.75 per mile. Taxi company B charges $ 6.00 to get into a cab and $ 1.25

7nadin3 [17]

Answer:

50 miles

Step-by-step explanation:

Let the miles traveled be x when cost for both taxi A and Taxi B is same

Lets calculate for Taxi A

charge to get in cab = $8

cost of traveling 1 mile = $ 0.75

cost of traveling for x miles = x * cost of traveling 1 mile= $ 0.75x

Total cost for traveling x miles = charge to get in cab +cost of traveling for x mile

Total cost for traveling x miles in Taxi A = $8 + $ 0.75x

______________________________________________

Lets calculate for Taxi B

charge to get in cab = $3

cost of traveling 1 mile = $ 1.25

cost of traveling for x miles = x * cost of traveling 1 mile= $ 1.25x

Total cost for traveling x miles = charge to get in cab +cost of traveling for x mile

Total cost for traveling x miles in Taxi B= $3 + $ 1.25x

As we have to find distance when cost for both is same

Thus

Total cost for traveling x miles in Taxi A=Total cost for traveling x miles in Taxi B

8 + 0.75x = 3 + 1.25x

8 - 3 = 1.25x - 0.75x

5 = 0.5x

x = 5/0.5 = 50

Thus, you must travel 50 miles so that cost in both the taxi A and Taxi B is the same

Which equation represents the graph function?

DENIUS [597]

Answer:

See below.

Step-by-step explanation:

First, it's obviously a line so the equation is a linear equation.

In order to find a linear equation, we first need the slope and the y-intercept. Recall the slope-intercept form: $y=mx+b$ , where m is the slope and b is the y-intercept.
