Answer:The whole numbers are the numbers 0, 1, 2, 3, 4, and so on (the natural numbers and zero). Negative numbers are not considered "whole numbers." All natural numbers are whole numbers, but not all whole numbers are natural numbers since zero is a whole number but not a natural number.

Write the equation of a line that is perpendicular to the given line and that passes through the given point.

katrin2010 [14]

Greetings and Happy Holidays!

<span>1) Perpendicular to </span> $-x+5y=14$
In order for lines to be perpendicular, their slopes must be negative reciprocals.
Example of slopes with negative reciprocals: 5 and $\frac{-1}{5}$

First, rearrange the equation into slope y-intercept form:
$-x+5y=14$

$5y=x+14$

$\frac{5y}{5}=\frac{x+14}{5}$

$y=\frac{1}{5}x+\frac{14}{5}$

The slope of the equation is: \frac{1}{5}

The negative reciprocal formula: $(m_{1})(m_{2})=-1$

Solve for the negative reciprocal:
$\frac{1}{5}m_{2}=-1$

Divide both sides by $\frac{1}{5}$
$\frac{\frac{1}{5}m_{2} }{ \frac{1}{5}} = \frac{-1}{ \frac{1}{5}}$

$m_{2}=(-1)(\frac{5}{1})$

$m_{2}=(\frac{-5}{1})$

$m_{2}=-5$

The slope of the new line is: -5

2) Passes through (-5,-2)

Create an equation with the slope discovered in slope y-intercept form.
$y=-5x+b$

Input the point the line passes through.
$(-2)=-5(-5)+b$

Solve for b (the y-intercept).
$-2=-5(-5)+b$

Multiply.
$-2=25+b$

Add -25 to both sides.
$(-2)+(-25)=b$

$-27=b$

The y-intercept is equal to -27

The Equation of the line is:
$y=-5x-27$

I hope this helped!

Is the number 15 prime or composite? prime composite Please help me. Will mark brainiest! Thats okay if you don't know don't ans

elixir [45]

Answer:

Hey there!

15 is composite. A composite number has factors other than one and itself. 15 has factors 3 and 5.

Thus, 15 is composite.

Let me know if this helps :)

If a calculator is sold for $19.20, then the revenue in dollars, R, generated by this item is given by the formula R=19.2q, whe

Alla [95]

The revenue generated will be $864 if 45 calculators are sold.

Step-by-step explanation:

Given,

Selling price of calculator = $19.20

Revenue generated = R = 19.2q

Where q represents the number of calculators sold.

If 45 calculators are sold, then

q = 45

Revenue generated = $19.2(45)$

Revenue generated = $864

The revenue generated will be $864 if 45 calculators are sold.
