Answer:

y>5/6

Step-by-step explanation:

5y+3>-7y+13

5y+7y>13-3

12y/12>10/12

y>5/6

This is an inequality, which shows where the variable y does or does not exist

from this we can say

y: (-infinity,5/6) (5/6, infinity]

or, y does not exist from (-infinity,5/6)

and does exist from (5/6, infinity]

If y varies inversely as x, and y = 23 when x<br> 8, find y when x 4.

Virty [35]

Answer:

y = 46

Step-by-step explanation:

Given y varies inversely as x then the equation relating them is

y = $\frac{k}{x}$ ← k is the constant of variation

To find k use the condition y = 23 when x = 8 , then

23 = $\frac{k}{8}$ ( multiply both sides by 8 )

184 = k

y = $\frac{184}{x}$ ← equation of variation

When x = 4 , then

y = $\frac{184}{4}$ = 46

Maya says that value of the 6 in 0.006 is 1/10 of the value of the 6 in 0.6 . Is she correct? Explain

Nikolay [14]

Answer:

Maya is NOT correct as

$\frac{1}{1000}$ is 1/100 of the value $\frac{1}{10}$

Step-by-step explanation:

The value of 6 in 0.006 = $\frac{1}{1000}$

Also, the value of 6 in 0.6 = $\frac{1}{10}$

But, $\frac{1}{1000}$ is not 1/10 of the value $\frac{1}{10}$

as 1/10 of the value $\frac{1}{10}$ = $\frac{1}{100}$

Hence,Maya is NOT correct.

$\frac{1}{1000}$ is 1/100 of the value $\frac{1}{10}$
