Answer:
x = 3/5
Step-by-step explanation:
Answer:
4 and 5
Step-by-step explanation:
xy = 20
x = 2y - 3
(2y-3)y = 20
2y^2 - 3y = 20
2y^2 - 3y - 20 = 0
Solve the quadratic equation
you get y = 4, -5/2
Use 5 since it is one of the options
xy = 20, y = 4
x = 5
Answer:
No
Step-by-step explanation:
since the magnitude of xy ≠ zw,
|x-y| = xy = |52-121|= 69, |z-w| = zw = |-21-25| = 46
69 ≠ 46
