21. Randy owns a computer store. In 1990, he sold 150 monitors. In 2000, he sold 900

lutik1710 [3]

Answer:

$y=75x+150$

Step-by-step explanation:

Let $y$ represent the number of monitors sold.

Given:

$x$ is the number of years since 1990.

So, for the year 1990, $x=0$ .

For the year 2000, 10 years passed. So, $x=10$ .

Now, monitors sold in 1990 are 150. So, at $x=0,y=150$

Monitors sold in 2000 are 900. So, at $x=10,y=900$

Thus, the two points are $(0,150)$ and $(10,900)$ .

The slope of a line with points $(x_{1},y_{1})$ and $(x_{2},y_{2})$ is given as:

Slope, $m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

For the points $(0,150)$ and $(10,900)$ , the slope is given as:

Slope, $m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\ m=\frac{900-150}{10-0}\\ m=75$

Now, the y-intercept is the point where $x=0$ . So, the point $(0,150)$ has $x$ value as 0.

So, the y-intercept is 150.

Equation of a line in slope-intercept form is given as:

$y=mx+b$

Where, $m$ is the slope and $b$ is the y intercept.

Here, $m=75$ and $b=150$ .

Therefore, the equation that represents the above data is given as:

$y=75x+150$

On a coordinate plane, a line goes through (negative 3, negative 3) and (negative 1, 5).

slega [8]

Answer:

y=20

x=4

Step-by-step explanation:

Since you can plug the first 2 coordinates into the slope equation ( $\frac{y_{2}-y_{1}}{x_{2} -x_{1} }$ ) you will get 4 for the slope so for the equation for the parallel line you would get y=4x+4 and since the x=4 you could plug that in and you would get y=20 and x=4

Find the domain of the graphed function.

Darya [45]

The domain of the graphed function is [-3, 2)

<h3>How to determine the domain and the range?</h3>

From the given graph, we have the following highlights:

Minimum x value = -3 (closed circle)
Maximum x value = 2 (open circle)

Open circles are represented with () while closed circles are represented with []

Hence, the domain of the graphed function is [-3, 2)

What is the image of the point (2, -3) after a rotation of 180° counterclockwise

horsena [70]

Answer:

(-2, 3)

Step-by-step explanation:

<em>When rotating a point 180 degrees counterclockwise about the origin our point A(x,y) becomes A'(-x,-y). So all we do is make both x and y negative</em>

<u>Point (2, -3) becomes:</u>

Point (-2, 3)
