Im being timedwhich number line represents the solution set for the inequality?​

Mathematics

Ludmilka [50]3 years ago

Answer:

The solution is:

-\frac{1}{2}x\ge \:4\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \:-8\:\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:-8]\end{bmatrix}

The number line graph of the solution is also attached below.

From the graph, it is clear that the 2nd number line represents the solution set for the inequality.

Step-by-step explanation:

Given the inequality

-\frac{1}{2}x\ge 4

Let us solve the inequality

-\frac{1}{2}x\ge 4

Multiply both sides by -1 (reverse the inequality)

\left(-\frac{1}{2}x\right)\left(-1\right)\le \:4\left(-1\right)

Simplify

\frac{1}{2}x\le \:-4

Multiply both sides by 2

2\cdot \frac{1}{2}x\le \:2\left(-4\right)

Simplify

x\le \:-8

Thus, the solution is:

-\frac{1}{2}x\ge \:4\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \:-8\:\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:-8]\end{bmatrix}

The number line graph of the solution is also attached below.

From the graph, it is clear that the 2nd number line represents the solution set for the inequality.

The missing number is 20

<h3>How to determine the number</h3>

We can see that the values at the top must be made equal to that at the bottom

For the top, we have

30 + 11 = 41

For the bottom, we should have:

21 + x = 41

Now, let's solve for 'x' to determine the missing figure;

21 + x = 41

collect like terms

x = 41 - 21

x = 20

Thus, the missing number is 20

On a coordinate plane, what is the distance between the point at (1, 9) and the point at (4, 9)? (Hint: Look at the x-coordinate
TiliK225 [7]

Answer:

The answer is 3 units apart.

Step-by-step explanation:

The points are (1,9) and (4,9). The y-coordinates are the same. The x-coordinates are different. To find the difference between them, you must subtract them. 4-1=3, so the points are 3 units apart!

I need to know how to solve <br> -4-(2+4(-6)-4-(2^2-5*2))
sweet-ann [11.9K]

Answer:

16

Step-by-step explanation:

This problem requires PEMDAS

Parentheses ( )

Exponents ^

Multiplication

Division

Add

Subtract

Start by solving anything in parentheses. There's an exponent within the parentheses, so we change that 2^2 into 4 and also make sure to multiply 5 x 2 before subtracting.

-4 - (2 + -24 - 4 - (4-10))

-4 - (2 + -24 - 4 - (-6))

Again, solve parentheses first.

-4 - (-22 - 4 - (-6))

-4 - (-26 + 6)

-4 - (-20)

-4 + 20

Answer is 16
