Answer:

the answer is the option D

$4\ units$

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The figure is a parallelogram

In a parallelogram,the diagonals bisect each other

so

$8=2x$ ------> $x=4\ units$

$12=3x$ ------> $x=4\ units$

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:

$y=75x+150$

1. Write an equation using equal fractions to represent this situation. Use a box to represent the total time it takes to paint

kondor19780726 [428]

Answer:

It takes 50 minutes to paint the whole box

Step-by-step explanation:

1. Write an equation using equal fractions to represent this situation. Use a box to represent the total time it takes to paint the bookcase.

Wilson paints 40% of a bookcase in 20 minutes.

For the total box

40% = 20 minutes

100% = x

40 × x = 100 × 20

x = 100 × 20/40

x = 50 minutes
