Answer:

You answer is C. 70 degrees.

Step-by-step explanation:

Since you have the two other Interior values, you know that when you add them (40+30), and then subtract it from 180, you will find that the other Interior angle is 110 degrees.

Now, an interior and exterior angle must add up to 180 degrees to be a correct angle. Since you know that the interior one is 110, you can figure out that the exterior angle will be 70 degrees.

110+x=180

110+70= 180

180=180

Checks out!

Interior angles in any triangle sum up to 180 so 180-(30+40)=110
So the exterior angles equals 180-110= 70

70 is the final answer i hope it helps and good luck

Can anybody show me the steps to answering this question? 7x - 2z = 4 - xy (solve for x)

Fed [463]

Answer: 2z+4/y+7

Step-by-step explanation:

We are trying to solve for x

7x-2z=4-xy

Add xy to both sides:

7x-2z+xy=-xy+4+xy= xy+7x-2z=4

Then you add 2z to both sides:

xy+7x-2z+2z=4+2z

xy+7x=2z+4

Then you factor out variable x

x(y+7)=2z+4

You divide both sides by y+7

x(y+7)/y+7= 2z+4/y+7

Which we would get x=2z+4/y+7

The function y = f(x) is graphed below. What is the average rate of change of the

stepladder [879]

Answer:

Average rate of change = 1

Step-by-step explanation:

Average rate of change of a function between x = a and x = b is defined by,

Average rate of change = $\frac{f(b)-f(a)}{b-a}$

We have to find the average rate of change of the function in the interval 2 ≤ x ≤ 4

Therefore, average rate of change of the function = $\frac{f(4) - f(2)}{4-2}$

From the graph attached,

f(4) = 4

f(2) = 2

Average rate of change = $\frac{4-2}{4-2}$

= 1

Therefore, average rate of change of the function in the given interval is 1.
