What is the rate of change for both of these tables. 25 pts

Rudiy27

Answer:

For the table on the left the rate of change is $22.8$

For the table on the left the rate of change is $-2$

Step-by-step explanation:

The range of change is the slope. The slope can be found with the following formula:

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

<u>For the table on the left</u>

Choose two points. In this case you can choose (-1,-24), (4,90)

You can say that:

$y_2=-24\\y_1=90\\\\x_2=-1\\x_1=4$

Substituting these values into the formula, you get:

$m=\frac{-24-90}{-1-4}\\\\m=22.8$

<u>For the table on the right</u>

Choose two points. You can choose (3,-6), (-6,12)

You can identify that:

$y_2=-6\\y_1=12\\\\x_2=3\\x_1=-6$

Substituting these values into the formula, you get:

$m=\frac{-6-12}{3-(-6)}\\\\m=-2$

What is the solution set of the equation 30/x^2-9 +1=5/x-3

gizmo_the_mogwai [7]

$\frac{30}{x^{2} - 9 + 1} = \frac{5}{x - 3} \\\frac{30}{x^{2} - 8} = \frac{5}{x - 3} \\5(x^{2} - 8) = 30(x - 3) \\5(x^{2}) - 5(8) = 30(x) - 30(3) \\5x^{2} - 40 = 30x - 90 \\5x^{2} + 50 = 30x \\5x^{2} - 30x + 50 = 0 \\5(x^{2}) - 5(6x) + 5(10) = 0 \\5(x^{2} - 6x + 10) = 0 \\\frac{5(x^{2} - 6x + 10)}{5} = \frac{0}{5} \\x^{2} - 6x + 10 = 0 \\x = \frac{-(-6) \± \sqrt{(-6)^{2} - 4(1)(10)}}{2(1)} \\x = \frac{6 \± \sqrt{36 - 40}}{2} \\x = \frac{6 \± \sqrt{-4}}{2} \\x = \frac{6 \± 2i}{2} \\x = 3 \± i \\x = 3 + i\ or\ x = 3 - i$

The answer is D.
