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 

The total nom of  code that can be used is equal to 5+3 = 8

The answer is in the image 

For every 8 cars there are 7 trucks

Therefore,

Cars:Truck=8:7

Answer is B)8:7

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg

Approximately it is aqual to 1300kg

Salesperson will make 6% of 1800

=(6/100)*1800

=108

Salesperson will make $108 in $1800 sales

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.
