Choose the graph that matches the inequality –x + y ≥ 2

Answer:

Step-by-step explanation:

-x + y >= 2

first of all, it means it includes the line (the "=" part).

that eliminates B and C.

then just look at the line function itself :

-x + y = 2

y = x + 2

and now

y >= x + 2

so, everything above the line (and again including the line), as every y value greater than or equal to the result of the line function is valid.

What is square root of 22

zmey [24]

Final Answer: $4.69$

Steps/Reasons/Explanation:

Step 1: You will need to find the perfect square root of a number that is less than $22$ . So $4^{2}$ is $16$ .

Step 2: Write down the square root of $16 = 4$ .

Step 3: Solve $\frac{22 - 16}{4 * 2}$ which is $0.75$ .

Step 4: Add $4 + 0.75 = 4.75$ , so $\sqrt{22}$ is approximately ≈ $4.7$ .

81 is 18% of what number? Enter your answer in the box.

prohojiy [21]

Answer:

450

Step-by-step explanation:

If 81 is 18% of a number then we can say that:

x × 0.18 = 81

We multiply by 0.18 because 18% is 0.18 as a decimal. So to work out the real number we divide 81 by 0.18:

81 ÷ 0.18 = 450

How to do distributive property using word problems?

Marta_Voda [28]

Well, I have an example that might help:

Rico's MP3 player holds songs of three different genres: grindcore, zydeco, and kuduro. There are 55 times as many grindcore tracks as there are zydeco tracks, and there are 77 times as many kuduro tracks as there are zydeco tracks. Let xx represent the number of zydeco tracks. Write an expression for the total number of tracks on the MP3 player, and simplify it.

Multiply the number of zydeco tracks by 55 to get the number of grindcore tracks.

5x5x

Multiply the number of zydeco tracks by 77 to get the number of kuduro tracks.

7x7x

Add up the numbers of all the tracks.

x+5x+7xx+5x+7x

Simplify using the distributive property.

=(1+5+7)x=13x=(1+5+7)x=13x

So, Rico's MP3 player holds 13x13x tracks.

I hope I helped you!

2x+6+3x=y is what y intercept

Ray Of Light [21]

The formula is y=mx+b, m being the slope and b being the y intercept.

So if you simplify your equation, it's 5x+6=y

Slope is 5, y intercept is 6

A car travels 182 kilometers in 4 hours with the constant speed. how much time will it take traveling 42 kilometers

Schach [20]

Answer:

55.38 min

Step-by-step explanation:

A car travels,

182 km ⇒ 4 hours

And we have to find the time that it takes to travel 42 km .

Lets make a equation.

Let the unknown time be x

182 km ⇒ 4 hours

42 km ⇒ x

To make easy let's km in to meters and hours in to minutes

182000 m ⇒ 240 min

42000m ⇒ x

Now use cross multiplication.

$182000x=240*42000\\$

$182000x=10080000$

$\frac{182000x}{182000} =\frac{1008000}{182000}$

$x =55.38min$

Hope this helps you.

Let me know if you have any other questions :-)
