x=9
Step-by-step explanation:
- -54 + 6x = 6 • (x - 9)
- Solve : 6 = 0
- Solve : x-9 = 0
- Add 9 to both sides of the equation : x = 9
A solution for a pair of lines means that they are equal to each other. This occurs when they instersect. Since the lines have the same slope, but are not the same line, they are parallel, so they will never intersect. This means there are zero solutions.
Hope this helps!
Answer:
$800 = $300 +.05(x), x being the amount that must be sold
Subtract 300 from both sides
$500= .05(x)
Divide by .05
x=$10000
Step-by-step explanation:
Px + qy = r
2px - qy = 2r
----------------add
3px = 3r
x = 3r/3p
x = r/p
