Which of the following is the correct graph of the solution to the inequality −8 greater than or equal to −5x + 2 > −38? (1 p
Svetlanka [38]

The inequality should read:

-8 \geq -5x + 2 > -38

Subtract 2 from all the terms:

-10 \geq -5x > -40

Divide all the terms by -5 to get x by itself (note that you flip the inequality signs as you divide by a negative):

\boxed{2 \leq x < 8}

The inequality is 2 ≤ x < 8.

A closed dot represents ≤, and an open dot represents <. Since x can represent all values between 2 and 8, you will shade in between 2 and 8 on the number line. x is greater than or equal to 2, so there will be a closed dot on 2. x is less than 8, so there will be an open dot on 8.

The answer is 'number line with a closed dot on 2 and an open dot on 8 and shading in between'.

What is -7n-4=24 lol i hate homework
Montano1993 [528]
It's a simple linear equation in 'n'.  There's only one number that 'n' can be
that will make the equation a true statement.  That number is called the
'solution' to the equation.  Here's one way to find it:

You said that                       <u> -7n - 4  =  24</u>

Add  4  to each side:           -7n       =  28

Multiply each side by  -1 :    7n       =  -28

Divide each side by  7 :         <em>n        =  -4</em>

Homework is the only way for most people to learn stuff.
