Which is the best approximation for the solution of the system of equations? y = x + 1 y = 3x – 2

a. (0.45, 0.88)
b. (0.88, 0.65)
c. (0.88, 1.1)
d. (1.3, 0.88)

The given equations are  y = x + 1and y = 3x – 2

Substituting y value in equation 1 from 2 we have :

3x-2=x+1

Subtracting x both sides

3x-x-2=1

2x-2=1.

Adding 2 both sides

2x=3

Dividing by 2

x=1.5.

Substituting x value in y=x+1

y=1.5+1.

y=2.5.

Solution is (1.5,2.5)

The approximate solution  is B. (0.88, 0.65)

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
