Answer:
<u>∠AEB = 72°</u>
Step-by-step explanation:
<u>Finding x</u>
- ∠AEB = ∠DEC (Vertically opposite angles)
- 7x - 5 = 2(4x - 8)
- 7x - 5 = 8x - 16
- 8x - 7x = -5 + 16
- x = 11
<u>Finding ∠AEB</u>
- 7x - 5
- 7(11) - 5
- 77 - 5
- <u>∠AEB = 72°</u>
Answer:
-4.5
Step-by-step explanation:
15(2-x)=13(3-x)
Expand parentheses:
30-15x=39-13x
Add 15x to both sides:
30=2x+39
Subtract 39 from both sides:
2x=-9
Divide both sides by 2:
x=-4.5
Hope this helps!
Answer:
Step-by-step explanation:
The domain of a function is all the allowed x values that make the function defined. There is nothing to make this function undefined. So the domain is negative infinity to positive infinity. All those x values are in the domain. In order to show your work, just show yourself plugging in those numbers.
You get 9, 0, and 1
