Which of the following values are solutions to the inequality -5 ≤ x + 5? A) -7 B) -10 C) -3

Answers

Answer 1

Answer:

Answer:

x ≥ -10

Step-by-step explanation:

We can solve the given inequality for the variable x by subtracting 5 from both sides:

-5 ≤ x + 5

- 5 - 5

-10 ≤ x

Optionally, we can swap the sides and flip the sign:

x ≥ -10

Further Note

The '≥' sign means "greater than or equal to", which means that the variable being compared can be either the exact value of the constant or anything greater than it.

What is the value of x that makes the given equation true? 2(x−8)=x+5x

Answers

First simplify the right side by combining like terms.

Since both terms contain an x, you can add them together.

So x + 5x simplifies to 6x.

So our equation now reads 2(x - 8) = 6x.

Solving from here, distribute the 2 through the

parentheses on the left side of the equation.

2(x) is 2x and 2(-8) is -16.

So we have 2x - 16 = 6x.

Now move the 2x to the right side by subtracting 2x from both sides.

This gives us -16 = 4x.

Now just divide both sides by 4 to get -4 = x.

Answer:

x = -4

Step-by-step explanation:

To find the value of x that makes a certain equation true means to solve the equation. You do this by rearranging the equation to make x the subject.

So,

2(x-8) = x+5x

2x - 16 = 6x

-16 = 6x-2x

4x = -16

x = -4
