Answer:

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

Step-by-step explanation:

Notice how it passed through at exactly (3,2) and (6,4).

By taking the formula for slope:

$m = \frac{rise}{run} = \frac{y}{x} \\ = \frac{2}{3}$

Substituting this into the slope-intercept form

y = mx + b

where m is the slope of the line and b is the y-intercept.

Since we were not given the y-intercept and the line started or passes through (0,0), we can safely assume that b = 0.

Therefore,

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

Tell whether the ordered pair is a solution of the equation. y = x - 5; (6, 11)

sashaice [31]

Answer:

Not a solution

Step-by-step explanation:

y=x-5

Plug in the point (6,11)

11=6-5

11=1

11≠1

Because the left side of the equation and the right side aren't equal, the ordered pair (6,11) is not a solution to the equation y=x-5.

I hope this helps!

How do I write Domain and Range in inequality notation?

ArbitrLikvidat [17]

Answer:

Domain: (-infinity, infinity) Range: (-infinity, infinity)

Step-by-step explanation:

They are parabolas, therefore you can assume that they go on infinitely. To find range, you must look at your y values. Look for your lowest point. Because the line goes done forever, your beginning mark would be (-infinity.

To find the other part, you look at your positive y values. Look for the highest value. Because this goes on infinitely, the completed version of your notation would be (-infinity, infinity). Be sure to use the infinity symbol though, which looks like an 8 rotated 90 degrees.

To find domain, look at your x values. To begin, look at your left-most values, which would be the negative numbers. Because the line goes on forever to the left, your notation would be (-infinity. To find the other part of domain, look at your positive x values. Because this line goes on infinitely as well, the completed version of your notation would be (-infinity, infinity). Infinity is never bracketed, it is always in parenthesis.

Brrunno [24]

Answer:

800

Step-by-step explanation:

Given: The selling price of bed is 2400.

Discount offered is 25%

Lets assume the cost of bed be "x"

Discount offered on the cost price of bed= $\frac{25}{100} \times x= 0.25x$
