<h2>Answer:</h2>

The inequality which is equivalent to the given inequality is:

        D.   y-8+2\leq -2+2

<h2>Step-by-step explanation:</h2>

We are given a inequality as:

               y-8\leq -2

which on simplifying gives.

i.e. on adding 8 on both side of the inequality we get:

      y\leq 6

A)

       y-8+8\geq -2+8

on simplifying we gets:

   y\geq 6

which does not matches the actual inequality.

Hence, option: A is incorrect.

B)

          y-8+8

on solving we get:

y

which is not equivalent to the given inequality.

Hence, option: B is incorrect.

C)

          y-8+2\leq -2+8

on simplifying we get:

 y-6\leq 6

Now on adding both side of the inequality by 6 we get:

    y\leq 12

which again does not matches.

Hence, option: C is incorrect.

D)

          y-8+2\leq -2+2

on simplifying we get:

     y-6\leq 0\\\\i.e.\\\\\\y\leq 6

It matches the actual expression.

      Hence, option: D is correct.

The actual length of a machine is 12.25cm , the measured length 12.2cm find the Absolute error .
NeX [460]

Answer:

Absolute error is 0.05 cm.

Step-by-step explanation:

Given:

Actual length = 12.25 cm

Measured length = 12.2 cm

We need to find Absolute error.

Solution:

Now we can say that;

Absolute error is equal to measured length minus Actual actual.

framing in equation form we get;

Absolute error = |Measured\ length - Actual\ length|= |12.2-12.25| = |-0.05|

Hence Absolute error is 0.05 cm.

Explain what a factor is. Feel free to use<br> examples to support your explanation.
Westkost [7]

Answer:

factors are basically numbers that can multiply by another number to get a certain number

Step-by-step explanation:

for example, the factors of 12: 1,2,3,4,6,12

you should count from the lowest to highest number to make it easier for u.

look at 1 and 12 in the sequence. 1 x 12 = 12

now look at 2 and 6. 2 x 6 = 12

now look at 3 and 4. 3 x 4 = 12

see what i mean?

an example of a non-factor would be 5. 5 can't multiply by anything to get 12. You need to find numbers between 1 and the certain number (12 in this example) and you need to find numbers that can multiply by another number to get that certain number but u can't go beyond the certain number. 7 can't multiply by anything to get 12. if u still don't understand, here is an easier way to help u.

the best thing to do is write the numbers from 1 - 12. 1 2 3 4 5 6 7 8 9 10 11 12

once u do that, you need to ask yourself: which numbers can multiply to get 12? 1 can multiply by a number to get 12. 2 can. 3 can. 4 can. <em>5 can't. </em>once you find a number that you can't multiply by, that is <em>not </em>a factor of the certain number you're looking for.

Hope this helps you :D
