Write an appropriate direct variation equation if y = 18 when x = 2

Sergeu [11.5K]

Answer:

$y=9x$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form $k=\frac{y}{x}$ or $y=kx$

In this problem we have

y=18 when x=2

Find the value of the constant of proportionality k

$k=\frac{y}{x}$ ----> $k=\frac{18}{2}=9$

therefore

The equation is equal to

$y=9x$

5/8-11/20=? Help what’s the answer I’m stuck on finding the LCM of the denominators

zhannawk [14.2K]

Answer:

3/40

Step-by-step explanation:

$\frac{5}{8} - \frac{11}{20}$
$\frac{25}{40} - \frac{22}{40}$ (LCM is 40)
$\frac{25-22}{40}$
$\frac{3}{40}$

Therefore, the answer is 3/40!

Simplify the following: 7-3[(n^3+8n)/(-n)+9n^2]

Pachacha [2.7K]

If you would like to simplify 7 - 3[(n^3 + 8n) / (-n) + 9n^2], you can do this using the following steps:

7 - 3[(n^3 + 8n) / (-n) + 9n^2] = 7 - 3[(-n^2 - 8) + 9n^2] = 7 - 3[-n^2 - 8 + 9n^2] = 7 - 3[ - 8 + 8n^2] = 7 - 3[8n^2 - 8] = 7 - 24n^2 + 24 = - 24n^2 + 31

The correct result would be - 24n^2 + 31.
