loris [4]3 years ago

Answer:

A. \frac{3 - 7}{-4 -(-7)} = \frac{-5 - 3}{2 - (-4)}

Step-by-step explanation:

Slope of PR = \frac{y_2 - y_1}{x_2 - x_1}

Where,

P(-7, 7) = (x_1, y_1)

R(-4, 3) = (x_2, y_2)

Slope of PR = \frac{3 - 7}{-4 -(-7)}

Slope of RT = \frac{y_2 - y_1}{x_2 - x_1}

Where,

R(-4, 3) = (x_1, y_1)

T(2, -5) = (x_2, y_2)

Slope of RT = \frac{-5 - 3}{2 - (-4)}

Therefore, the proportion that can be used to show that the slope of PR = the slope of RT is:

\frac{3 - 7}{-4 -(-7)} = \frac{-5 - 3}{2 - (-4)}

You first have to turn 2x + 4y = -8 into y = mx + b before graphing. To do this, you subtract 2x from the left side of the equation because inverse operations. This will bring 2x to the right side. Now, you will have 4 = -2x + 8. However, you cannot have a number with y. Therefore, you must divide -8 and 2 by 4. You will get y = -1/2 x + 2 as your equation. 
To graph -1/2x + 2, you must remember rise/run. Since it is NEGATIVE -1/2, your slope will go downwards (1 down, 2 across) starting from y = 2.

Eira created color panels for a wall using a mix of only red and blue paints. She plotted the quantities of red and blue paints
lesya [120]

Answer:

3 ≤ x ≤ 7 or x is between 3 and 7, inclusive

Step-by-step explanation:

Eira's graph probably resembled the diagram below.

The domain is the set of all possible x-values that will make a function work.

x can take any value from 3 to 7.

The domain is [3, 7] or 3 ≤ x ≤ 7.
