3x - y = 2 convert the standard form to slope intercept form (y=mx+b)

The standard form:

1.

         subtract 5x from both sides

         change the signs

2.

          add 4x to both sides

3.

    multiply both sides by 3

     subtract 2x from both sides

     change the signs

4.

    multiply both sides by 2

       add x to both sides

5.

      add 5x to both sides

6.

     multiply both sides by 4

     subtract 3x from both sides

      change the signs

The answer is in the image 

SI=(P*R*T)/100

P=2000

R=1.5

T=6

SI=(2000*1.5*6)/100

=(2000*9)/100

=180

Neil will earn interest of 180

The answer is in the image 

y=2x+15

where y=Value of coin

x=Age in years

Value of coin after 19 years=2*19+15

=$53

Therefore, Value after 19 years=$53

The answer is in the image 

Speed=Distance/time

Here,

distance=15m

time=1sec

speed=15/1=15m/sec

Distance=Speed*time

time=15min=15*60sec=900sec

Distance travelled in 15 min=15*900=13,500m

=13500/1000 km=13.5Km

The wood before starting =12 feet

Left wood=6 feet

Wood used till now=12-6=6 feet

Picture frame built till now= 6/(3/4)

=8 pieces

Therefore, till now 8 pieces have been made.
