No it does not. when solved you should get y=3/x, meaning it shows inverse variation.
Answer:
439 x 0.4 = 175.6 so the discount is 175.6
Step-by-step explanation:
40% is equal to 0.4 and you just multiply. If you want to find the discount price just subtract the discount off.

Answer:
y= -2x........eqn i
y=5x+3......eqn ii
substituting the value of Y from eqn i in eqn ii, we get,
-2x=5x+3
-7x=3
x= -3/7
so, y= -2x= -2× (-3/7)
so, y= 6/7
Answer:
z = 0
Step-by-step explanation:
Step 1: Write equation
9z - 5 - 4z = -5
Step 2: Solve for <em>z</em>
- Combine like terms: 5z - 5 = -5
- Add 5 to both sides: 5z = 0
- Divide both sides by 5: z = 0
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
9(0) - 5 - 4(0) = -5
0 - 5 - 0 = -5
-5 = -5
