Answer:

x= -10

Step-by-step explanation:

7x-4(-4x-16)=-166 foil the ()

7x+16x+64= -166  combine terms

23x+64= -166  subtract 64 to both sides

23x= -230  divide by 23

x= -10

Hey!

----------------------------------------------------------------

We Know:

m∠AED = 34°

m∠EAD = 112°

----------------------------------------------------------------

Solution:

You notice 4 small triangles in both triangles. That shows that both triangles are the same.

The angles are the same for m∠BDC and m∠AED.

The angles are the same for m∠ADB and m∠EAD

----------------------------------------------------------------

Angles:

m∠BDC = 34°

m∠ADB = 112°

----------------------------------------------------------------

Congruent Angles:

m∠AED ≡ m∠BDC

m∠EAD ≡ m∠ADB

----------------------------------------------------------------

Hope This Helped! Good Luck!

Answer: Slope is -1

Using the slope formula, we get

m = (y2 - y1)/(x2 - x1)

m = (0 - 4)/(2 - (-2))

m = (0 - 4)/(2 + 2)

m = -4/4

m = -1

What's going on here is that we subtract the y values 0 and 4 to get -4. This means that we dropped 4 units vertically to go from A to B. This is the rise. So rise = -4

The run is 4 because we moved 4 units to the right to go from A to B. This is found algebraically when we subtracted the x coordinates, so 2 - (-2) = 2 + 2 = 4.

Slope = rise/run = -4/4 = -1

You have the correct answer, assuming you wrote -1. I think your teacher just marked it wrong because you forgot to show steps.
