Plz help me Thx so much
Degger [83]

Answer:

shipping and handling is <u>18.90</u> dollars

Step-by-step explanation:

percent means "per one hundred", so any percent can be written as a fraction over 100

30% = 30/100 = 0.30

Multiply 0.30 with the price 63 to get 0.30*63 = 18.90, which is the cost of shipping only. This result is added on top of the 63 dollars to get the total cost.

Cloud [144]

The form which should be used when you know the slope of a line and one of the points on the line is: d. point-slope form.

<h3>What is the point-slope form?</h3>

The point-slope form can be defined as an equation which is used when the slope of a line and one of the points on this line is known.

Mathematically, the point-slope form of a line is given by:

y - y₁ = m(x - x₁)

<u>Where:</u>

  • m is the slope.
  • x and y are the points.

In conclusion, you should use the point-slope form when you know the slope of a line and one of the points on the line is given.
