If f ( x ) = 5 x - 7
f ( 5 ) = 5 * 5 - 7 = 25 - 7 = 18
- 5 is in the domain
g ( 5 ) = √ ( 5 - 2 ) = √ ( - 3 ) ( this is an irrational number )
- 5 is not in the domain.
Gallons! gallons!! GALLONS!!! GALLONSSS!!!! hahaha. They're all the same so C. gallons. :).....xD
A would be (-3, 6).
B would be (-6, 3).
Anytime something is asking you to reflect off of the Y-axis, you put the original but flipped. Also, your answer will always be straight across vertically.
angle 1 + angle 3 = 27 +43 = 70
angle 2 = 180-70 = 110
angle 2 + angle 4 = 180
180 -angle 2 = angle 4 = 180-110 = 70
angle 4 = 70 degrees
