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:
$32
Step-by-step explanation:
Take 2 points
(3, 9) and (0, 3)
Slope = (Y2 -Y1) ÷ (X2 -X1)
<span>Slope = (3-9) / (0-3)
</span><span>Slope = -6 / -3
</span><span>Slope = 2
The equation will have the form </span><span>y = mx + b</span>
We can rearrange this to b = y -mx
Let's take one of the points (3, 9) and the slope (m) and enter it into the formula:
b = -9 -2*3
b= -3
Now we enter all that data into b = y -mx
and get
y = 2x -3
This has infinitely many solutions if that is all that the question asked...
2x+3y=12
3y=-2x+12
y=(-2x+12)/3
So for any value of x you choose it will give you the corresponding y value that makes your original equation true.
