Answer:
y = -x/2 + 1/2 or
y = -1/2 x + 1/2
(these are equivalent)
Step-by-step explanation:
Slope-intercept form is:
y = mx + b
So we have to get the y all by itself on the left.
2y + x = 1
Subtract x from both sides.
2y = 1 - x
Divide both sides by 2. Divide all the terms by 2.
2y/2 = 1/2 - x/2
Simplify.
y = 1/2 - x/2
Rearrange the terms on the right side so that the x term is first and the constant is last.
y = -x/2 + 1/2
I think this is a good, reasonable and correct answer. But maybe you really want to see that m number (the slope) out in front of the x. Then you can write is as:
y = -1/2 x + 1/2
Answer:
subtract 5 from each side z=2
Step-by-step explanation:
Answer:
5.5
Step-by-step explanation:
Squaring both sides
I would use the equation
24 + 8x = 112
let x = the amount of CDs she bought.

Answer:
The number of years it will take for them to be the same height is 6 years
Step-by-step explanation:
Here we have a question relating to optimization
Let the number of years at which they will be the same height be M
we then have
2 ft + (25/12 × M) ft= 10 ft + (9/12 × M) ft which gives
→ (25/12 × M) ft - (9/12 × M) ft = 10 ft - 2 ft
→ (25/12 × M) ft - (9/12 × M) ft = 8 ft
→4/3 M ft = 8 ft
Therefore, M = (8 ft)÷(4/3 ft) = 6
Therefore, it will take 6 years for them to be the same height.
