Answer:
1 and 3
Step-by-step explanation:
If the two numbers are x and y, then:
x + y = xy + 1
x − y = xy − 5
Subtract the two equations:
(x + y) − (x − y) = (xy + 1) − (xy − 5)
x + y − x + y = xy + 1 − xy + 5
2y = 6
y = 3
Solve for x:
x + 3 = 3x + 1
2 = 2x
x = 1
The numbers are 1 and 3.
Answer:
y=-2/5x+5
Step-by-step explanation:
Answer:
AB = 35
Step-by-step explanation:
For the value of variable z....;
;Perimetre = 132
; 132 = 2(4z + 3) + 2(5z)
; 132 = 8z + 6 + 10z
; 132 - 6 = 8z + 10z
; 126 = 18z
;the value of...z = 7
Therefore the value of length AB;
AB = 5z...then substitute the value of z into the length of AB
; AB = 5(7)
;AB = 35
