The value of x varies with y and when x=1/3 y=12 write an equationto represent the variation
Virty [35]

Answer:

y = 36x

Step-by-step explanation:

Given that x and y vary directly then the equation relating the is

y = kx ← k is the constant of variation

To find k use the condition x = \frac{1}{3}, y = 12, then

k = \frac{y}{x} = \frac{12}{\frac{1}{3} } = 12 × 3 = 36

y = 36x ← equation of variation

Solve each system using the substitution method 6x-y=-4 and 2x+2y=15
Fynjy0 [20]
Convert 6x - y = -4 into y = mx + b
Y - 4 = 6x
Y = 6x + 4
Substitute that into second equation
2x + 2(6x + 4) = 15
2x + 12x + 8 = 15
14x = 7
X = 1/2
6(1/2) - y = -4
3 - y = -4
-y = -7, y = 7
Final answer: x = 1/2, y = 7
