Answer:
x = 1
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 12 when x = - 2, then
k = = = - 6, thus
y = - 6x ← equation of variation
When y = - 6, then
- 6 = - 6x ( divide both sides by - 6 )
2 5/8 is the number.
1 thing =$26.60 for $133
85+x+x=89
85+2x=89
2x=89-85
2x=4
x=2
So she would need 89+2=91
[1] x² - 4/2x - 4
[2] 4 - 3x/2x + 4
[3] x²/2x² - 2
[4] x² + 5/5 - x
[5] - x³/x² - 4
[6] x + 3/x³ - 1
[7] 5 - x²/3x²
[8] - 2x + 6/2x³ - 3
[9] 4x²/- 3x² + 1
[10] 4x - 1/6x + 1
[11] x² - 1/x² + 1
