Examine the following table, which defines the relationship y= f(x). Then, answer the question.

erastova [34]

The slope of the function is most positive either side of x=0 and x=2π.

On the interval [0, π/4], the average slope is $\dfrac{(\frac{\sqrt{2}}{2})}{(\frac{\pi}{4})} = \dfrac{2\sqrt{2}}{\pi}$

On the interval [7π/4, 9π/4], the average slope is $\dfrac{(\frac{\sqrt{2}}{2}-\frac{-\sqrt{2}}{2})}{(\frac{9\pi}{4}-\frac{7\pi}{4})}=\dfrac{2\sqrt{2}}{\pi}$

The average rate of change is highest on the intervals [0, π/4] and [7π/4, 9π/4].

What is the value of x in the equation 3x - 4 (2x - 5) = 15

Zepler [3.9K]

Hey there! I'm happy to help!

Here is our equation

3x - 4 (2x - 5) = 15

First, we will sue the distributive property to remove the parentheses. The term outside the parentheses is -4, so that is what we multiply the insides by.

3x-8x+20=15

We combine our like terms (our x-values).

-5x+20=15

We subtract 20 from both sides.

-5x=-5

We divide both sides by -5.

x=1

Have a wonderful day and keep on learning! :D

What are the values of p and q?

Reptile [31]

Answer:

q = 94

p = 18

Step-by-step explanation:

The triangles are congruent so q = 94

Add q + 68 same as 94 + 68 = 162

Subtract 162 from 180 to get p

180 - 162 = 18

Hope this helps!
