Answer:
3^5=9^2x = 3
3^(2x+1) =3^3 = 1
Step-by-step explanation:
C because the hypotenuse is the longest
The last one, d, 2/3 < g < 2
Answer:
R(-3, 8)
Step-by-step explanation:
R = 2Q -P
R = 2(4, 3) -(11, -2) = (8-11, 6+2)
R = (-3, 8)
_____
You can derive the formula for the endpoint from the formula for the midpoint:
Q = (R + P)/2
R = 2Q - P . . . . . . multiply by 2 and subtract P
