Answer:
<em>1. B.</em>
<em>2. B.</em>
Step-by-step explanation:
<u>Trigonometry</u>
1) Coterminal angles can be found by adding or subtracting 360° (or 2\pi radians) to a given angle. If we have 120°, adding 360° gives 480°, adding again 360° gives 840°. There is no way to get -180°, so this option is not a coterminal angle to 120°
2)
A. 
, and not undefined
B. 
. This is correct
C. 
is undefined, not zero
Thus the only correct option is B.
Answer:
Add 7 to both sides
Step-by-step explanation:
The equation has to be just x = y
There cannot be another number on the same side as the variable
Now that we did that, the equation is 9x = 0
x = 0
Well, that was easy lol
Answer:
D
Step-by-step explanation:
gradient= change in y
__________
change in x
m= y2_ y1
______
x2- x1
m= -14- 2
_____
5-1
m= -16
___
4
m= -4
Answer:
780
Step-by-step explanation:
For this we have to find the 20% of $975.00
= 20% of 975
= 20/100 (975) (Removing percentage sign gives us 100)
= 0.2 (975)
= 195 (that's the 20% of 975 which is taken)
NOW,
Subtract 195 and 975 to find the remaining amount
= 975 - 195
=780 Answer
