Since y is anything greater than 2, you would draw a straight line across the point (from left to right) and if you had to shade you would shade above it (:

Which expression is equivalent to (3/x − 2 − 5) / (2 − 4/x − 2)?

Tresset [83]

Answer:

last option is correct

Step-by-step explanation:

$\frac{\frac{3}{x-2} -5}{2-\frac{4}{x-2} } = \frac{3-5x+10}{2x-4-4} = \frac{13-5x}{2x-8}$

What is the slope of the line represented by the points in the table?

kotykmax [81]

To find the slope(m) of the line, you can use the slope formula:

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

and plug in 2 points.

You can use any of the points, I will be using the points (0, -0.25) and (1, -0.2)

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

$m = \frac{-0.2 - (-0.25)}{1-0}$

$m = \frac{-0.2 + 0.25}{1-0}$

$m = \frac{0.05}{1}$

m = 0.05 (The last answer)

Dana is filling a 1.5 gallon watering can at a rate of 0.75 gallon per minute. What is the domain of the function that represent

Butoxors [25]

Answer:

0 ≤ x ≤ 2

Step-by-step explanation:

A function show the relationship between an independent variable and a dependent variable. The independent variable (input) does not depend on other variables while the dependent variable (output) depend on other variables.

In this question, the volume of the water is the dependent variable and the time taken is the independent variable. Let y represent the volume of the water and x represent the time taken. Therefore:

y = 0.75x

The domain of the function is the set of independent variable, it can be gotten by determining x when y is minimum and maximum. Hence:

For y = 0

0 = 0.75x

x = 0/ 0.75 = 0

For y = 1.5 gallon

1.5 = 0.75x

x = 1.5/0.75 = 2

Hence, the domain = 0 ≤ x ≤ 2
