Step-by-step explanation:
We need to find each of the following as a rational number in the form of p/q
(a) (3/7)² (b) (7/9)³ (c) (-2/3)⁴
Solution,
(a) (3/7)²

(b) (7/9)³

(c) (-2/3)⁴

Hence, this is the required solution.
Bill paints 1/2 per hour. Bob paints 1/3 per hour. 1/2x+1/3x=1
25 to 75 in lowest terms:
25:75 = 1:3
Slope -5/4
y-intercept -0,5
use form y=mx+b
y=-5/4x+-5
