suppose y varies directly with x, an dy = 10 when x =3. what direct variation equations relates x and y?

Ratling [72]

The direct variation equation relates x and y is y = $\frac{10}{3}$ x

Step-by-step explanation:

Direct variation is when one variable is equal to a constant times another variable

If y varies directly with x, then

y ∝ x
y = k x is the equation of variation
k is the constant of variation

∵ y varies directly with x

∵ y ∝ x

∴ y = k x

∵ y = 10 when x = 3

- Substitute these values in the equation above to find k

∴ 10 = k(3)

∴ 10 = 3 k

- Divide both sides by 3

∴ k = $\frac{10}{3}$

∴ The equation of variation is y = $\frac{10}{3}$ x

The direct variation equation relates x and y is y = $\frac{10}{3}$ x

4 x plus 8 y equals 40, when y equals 0.8?

Over [174]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{x = 8.4}}}}}$

Step-by-step explanation:

Given, y = 0.8

To find : value of x

$\sf{4x + 8y = 40}$

plug the value of y

$\longrightarrow{ \sf{4x + 8 \times 0.8 = 40}}$

Multiply the numbers: 8 and 0.8

$\longrightarrow{ \sf{4x + 6.4 = 40}}$

Move 6.4 to right hand side and change it's sign

$\longrightarrow{ \sf{4x = 40 - 6.4}}$

Subtract 6.4 from 40

$\longrightarrow{ \sf{4x = 33.6}}$

Divide both sides by 4

$\longrightarrow{ \sf{ \frac{4x}{4} = \frac{33.6}{4} }}$

Calculate

$\longrightarrow{ \sf{x = 8.4}}$

Hope I helped!

Best regards ! :D
