Equivalent expression for 4(2x+1) and for 1/2 (4x-8)​
stellarik [79]

Answer:

8x+4 and 2x-4

Step-by-step explanation:

We are going to use factoring to make equivalent expressions. What you do is you take the number next to the parenthesis and multiply it with what is inside the parenthesis. So it would be 8x+4 and 2x-4. Hope this helps! :)

Solving systems of linear inequalities ​
Liono4ka [1.6K]

Answer:

To solve a system of of linear inequalities, you could do the elimination method or substitution method.

Step-by-step explanation:

  • For elimination method, you can add the same value to each side of an equation. So if you have a system: x – 6 = −6 and x + y = 8, you can add x + y to the left side of the first equation and add 8 to the right side of the equation.

For substitution method, you have to:

Step 1 : First, solve one linear equation for y in terms of x.

Step 2 : Then substitute that expression for y in the other linear equation.

Step 3 : Solve this, and you have the x -coordinate of the intersection.

Step 4 : Then plug in x to either equation to find the corresponding y -coordinate.

Hello!!! Can u help me with this: 2 - (-8) = ?
alekssr [168]

We are given the following problem

2-(-8)

As you can see, the negative sign is being multiplied with a negative sign.

Recall that when a negative sign is multiplied with a negative sign then the result is a positive sign.

2-(-8)=2+8=10

Therefore, the result is positive 10
