An integer is a whole number and the product of numbers means to multiply them. So so we know that:
x * y = x - 50
So the product (x * y) is 50 less than one of the integers ( x - 50)
I can divide both sides by x:
y = (x - 50) / x where x is not zero
y = x/x - 50/x
y = 1 - 50/ x
x can no longer be zero since you cannot divide by zero
the only way for y to be a whole number is if 50/x is a whole number. 50/x can onky be a whole number if x is a factor of 50. so take any factor of 50 and that will be possible answers.
factors of 50: 1,2,5,10,25,50
these would be possible x values. To to find corresponding y values plug in x
y = 1 - 50/1
y = 1 - 50
y = -49
So first pair is (1, -49)
do the same for the rest and get
(2, -24)
(5, -9)
(10, -4)
(25, -1)
(50, 0)

Answer:
Slope is -2/7
Step-by-step explanation:
Slope formula is y₂-y₁/x₂-x₁
So...
(x₁,y₁) and (x₂,x₂) →(2,2) and (-5,4)
4-2= 2
-5-2= -7
2/-7
If you would like to solve the inequality x - 5/x < 4, you can do this using the following steps:
<span>x - 5/x < 4
</span>x^2 - 5 < 4x
x^2 - 4x - 5 < 0
(x - 5) * (x + 1) < 0
x < 0
1. x = 5
2. x = -1
The correct result would be x = -1.
