(alternate segment theorem)
(angles in a triangle add to 180 degrees)
Answer:
1. C) 3
2. D) -1
3. D) 7^2 - 8*2 - 16
4. B) 75
5. B) 6^2 + (2 - 8)*sqrt(81)
Step-by-step explanation:
1. (10 - (6-4)^2)/2
= (10 - 2^2)/2
= (10 - 4)/2
= 6/2
= 3
2. PEMDAS states that Multiplication is before Subtraction
8 - (5^2-7)/2
= 8 - (25-7)/2
= 8 - 18/2
= 8 - 9
= -1
3. D) 7^2 - (8*2) - 16
= 49 - 16 - 16
= 49 - 32
= 17
4. 3(2 + 3)^2
= 3(5)^2
= 3(25)
= 75
5. 6^2 + (2 - 8)*sqrt(81)
= 36 + (-6*9)
= 36 - 54
= -18
Answer:
354294
Step-by-step explanation:
729/3=243
243*243=59049
59049*6=354294
Elimination method means you're essentially. "subtracting" one equation from another.
x-y=17
- x+y=-1
---------
-2y=18
Now we'll solve x+y=-1 and -2y=18 separately.
-2y=18
Divide both sides by -2.
y=-9
x-9=-1
Add 9 to both sides.
x=8
The solutions are x=8 and y=-9, or (8,-9).
