How do I solve: 22-6x>4
uysha [10]

Answer:

22-6x>4  

One solution was found :

                  x < 3

Rearrange:

Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :  

                    22-6*x-(4)>0

Step-by-step explanation:

Step  1  :

Pulling out like terms :

1.1     Pull out like factors :

  18 - 6x  =   -6 • (x - 3)  

Equation at the end of step  1  :

Step  2  :

2.1    Divide both sides by  -6  

Remember to flip the inequality sign:  

Solve Basic Inequality :

2.2      Add  3  to both sides

            x < 3

Inequality Plot :

2.3      Inequality plot for

        -6.000 X  + 18.000  <  0

The slope intercept form of the equation of a line that passes through point (-2, -13) is y = 5x - 3. What is the point slope fo
Alona [7]

Answer:

B. y+13=5(x+2)

Step-by-step explanation:

I personally do y=_+_(x-_) when solving these equations

Plug in -2 the x coordinate for (x- (-2) to be (x+3)

Plug in -13 for the y intercept.

5 from 5x is the slope.

Thus y=-13+5(x+3)

Then just move 13 to the other side

A lawn mower was originally priced at $450 but went on sale for 20% off. If Maurice bought the lawn mower and paid 5% sales tax,
Lelu [443]

Answer:

$378

Step-by-step explanation:

Full price:  1.00($450) = $450

20% off:     0.20($450) = $90

Sale price (after 20% off):  (1.00 - 0.20)($450) = 0.80($450) = $360

Final price, including tax:  (1.00 + 0.05)($360) = $378
