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:

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

For the table on the left

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:

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

For the table on the right

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:

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

Two sides of an isosceles triangle have lengths of 4 and 8. What is the length of the third side?

Gnoma [55]

Answer:

Step-by-step explanation:

Let's start with a simple fact: two sides of an isosceles triangle must be equal. Let's suppose the missing side is 4

That would mean that 4 + 4 equals 8. You must pick a side that exceeds 8, but you loose the property of 2 sides need to be equal.

So the answer has to be 8. The final size of the sides is 4 8 and 8. 4 and 8 exceed the third side (8).

8 and 8 certainly exceed 4.
