Help me with inequality
Hoochie [10]

Answer:

  C.  x > 3

Step-by-step explanation:

As long as you don't multiply or divide by any negative numbers*, <em>you can solve this the same way you would an equation</em>.

  3x +2 > x +8

  3x > x +6 . . . . . . subtract 2

  2x > 6 . . . . . . . . subtract x

  x > 3 . . . . . . . . . .divide by 2; matches choice C

_____

* The complete rule is "as long as you don't use any order-changing operations, ...". There are some functions you can apply to both sides of the inequality that will change the ordering. Multiplication or division by a negative number is only one of many.

  1 < 2

  -1 > -2 . . . . . multiplication by -1 reverses the order

The ordinate is twice the abscissa
zepelin [54]

We can construct the function:

f(x)=2x

Where f(x) or y is ordinate and x is abscissa.

The function actually represents a line. Since it can have linear form.

f(x)=2x+0

Hope this helps.

What is the length of ac <br> help pls
Lelu [443]

Answer:

x=2

Step-by-step explanation:

This is an isosceles triangle you can tell by the two congruent/equal angles

angle A is congruent/equal to angle C by definition the two sides will be equal.

x-4=3x-8

1. get all you x's on one side. by subtracting x from both sides you don't have to deal with dividing by negatives later on.

x-x-4=3x-x-8

-4=2x-8

now you want to get x by itself so add 8 to both sides

4= 2x

x is still not by itself so divide both sides by 2

x=2
