What is y=-4/3x+2 in point slope form?

Shtirlitz [24]

Answer:

$y-2=-\frac{4}{3}(x-0)$

Step-by-step explanation:

we know that

The equation of the line in point slope form is equal to

$y-y1=m(x-x1)$

we have

$y=-\frac{4}{3}x+2$ ---> equation in slope intercept form

Convert to point slope form

subtract 2 both sides

$y-2=-\frac{4}{3}x$

Rewrite as

$y-2=-\frac{4}{3}(x-0)$

the slope is $m=-\frac{4}{3}$

the point is $(0,2)$

A salesperson receives a 2.5% commission on sales, what commission does the salesperson receive for $8,000 in sales

Tcecarenko [31]

Percentage of commission received by the salesperson = 2.5%
Amount of sales made by the salesperson = $8000
Then
The amount of commission received by the salesperson = (2.5/100) * 8000 dollars
= 2.5 * 80 dollars
= 200 dollars
So the salesperson receives a commission of $200 on the total sales made. I hope the procedure is clear enough for you to understand. You can use this method in future for solving similar problems without requiring any help from outside.

Oksanka [162]

Answer:8: 21

Step-by-step explanation:

Given : An architect builds a model of a park in the shape of a rectangle. The length of the model = 40.64 centimeters

The width of the model = 66.04 centimeters

Since, .

Then ,

Now, the length of the model =

The width of the model =

Sum of length and width = 16+26=42 inches

Now, the ratio of the length to the sum of the length and width in inches :_

Hence, the ratio of the length to the sum of the length and width in inches in simplest form = 8:21

Use z scores to compare the given values. Based on sample data, newborn males have weights with a mean of 3227.9 g and a standa

sasho [114]

Answer:

The weight that is more extreme is the male which is -2.62

Step-by-step explanation:

Consider the provided information.

Now use the z scores formula:

$z=\frac{x-\mu}{\sigma}$

Where μ is mean and σ is the standard deviation.

For newborn males have weights with a mean of 3227.9 g and a standard deviation of 659.9 g.

Substitute the respective values in the above formula.

$z=\frac{1500-3227.9}{659.9}\approx-2.62$

For Newborn females have weights with a mean of 3073.1 g and a standard deviation of 806.8 g.

Substitute the respective values in the above formula.

$z=\frac{1500-3073.1}{806.8}\approx-1.95$

So, the more extreme of these is the male which is -2.62
