The graph models function R. The table of values models function S. Which statement is true about these functions?

vagabundo [1.1K]

Answer: OPTION D.

Step-by-step explanation:

The rate of change of a linear function is also known as "Slope".

The slope can be calculated with the following formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

Choose two points on the function "R" graphed:

$(1,0)\\(0,-3)$

You can say that:

$y_2=-3\\y_1=0\\\\x_2=0\\x_1=1$

Substituting values into the formula, you get:

$m=\frac{-3-0}{0-1}=3$

Choose two point from the table that models the function "S":

$(4,21)\\(6,31)$

You can say that:

$y_2=31\\y_1=21\\\\x_2=6\\x_1=4$

Substituting values into the formula, you get:

$m=\frac{31-21}{6-4}=5$

Therefore, you can conclude that the function "S" has a greater rate of change than Function "R".

"two angles are supplementary. the measure if one angle is 10 mire than three times the other. Find the measure of each angle.".

jolli1 [7]

If two angles are supplementary, their measures add to 180 degrees.

Let’s name the angles A and B.

You can substitute or replace angle B in the first equation with the second equation like so:

4
So, angle A is 42.5 degrees and angle B is 137.5 degrees!

Find the measure of angle2 A. 90 B. 50 C. 60 D. 30

galina1969 [7]

I think it is C. 60.
You can eliminate A because it is not a right angle, and D because the angle is bigger than the given angle. So it is between 50 and 60, and I hope this is right and the picture makes sense
