Answer:

The answer to your question is x = 40°

Step-by-step explanation:

According to the picture we determine that the triangle to the right is isosceles so two of its angles are equal.

Remember that the sum of the internal angles in a triangle equals 180°

2x° + 100° = 180

- Subtract 100 in both sides

2x + 100 - 100 = 180 - 100

- Simplify

2x = 80

-Divide both sides by 2

2/2 x = 80/2

Simplify and result

x = 40°

Let f(x)=−12(x+2)2+5 . What is the average rate of change for the quadratic function from x=−3 to x = 1?

aev [14]

Answer:

Average rate of change = -6

Step-by-step explanation:

The average rate of change over the interval (a,b) is given by;

[ f(b) - f(a)] / (b-a)........................where interval is (a,b)

(a,b) interval =(-3,1)

Where;

f(x)= -12 (x+2)² +5

$f(a)=f(-3)=-12(-3+2)^2+5\\f(a)=f(-3)=-12(-1)^2+5\\f(a)=f(-3)=-12(1)+5\\=-12+5=-7\\\\\\f(b)=f(1)=-12(1+2)+5\\f(b)=f(1)=-12(3)+5\\=-36+5=-31\\\\f(b)-f(a)=-31--7=-24\\\\b-a=1--3=4\\\\f(b)-f(a)/b-a=\frac{-24}{4} =-6$

Here’s another one free 50 points and brainiest, first come first serve!<br> 4x+5-10+3x=57

GarryVolchara [31]

So we have to simplify this equation:
4x+5-10+3x=57
Add like terms:
7x-5=57
Then add 5 to both sides:
7x=62
x=62/7
