Which statement correctly explains weather the equation y = x^2 - 2 represents a function ?

9514 1404 393

Answer:

  1 < x < 29

Step-by-step explanation:

The triangle inequality requires the sum of the two shortest sides exceed the longest side.

When x and 14 are the shortest:

  x + 14 > 15

  x > 1

When 14 and 15 are the shortest:

  14 +15 > x

  29 > x

Then the requirement for the length of x is ...

  1 < x < 29

The length of the third side of a triangle can be between the difference and sum of the two given sides.

Answer:

y = -2/5x -6 I think!!

Step-by-step explanation:

Answer:

y-intercept - 120

slope - -8x

Step-by-step explanation:

If you remember y=mx+b, m is the slope and b is the y-intercept.

Hope this helps! :)

Answer:

YOUR THE ONE WHO NEEDS TO ASK THE QUESTION

Step-by-step explanation:

Answer:

Step-by-step explanation:

Flat rate is the y- intercept b = 11.2

Charge per mile is the slope m = 3.1

The equation is:

Answer:

[tex]t=4.4594[/tex]

Step-by-step explanation:

We can take the log 2 of both sides to get [tex]t=\log_2(22)[/tex].

We know that [tex]2^4<22<2^5[/tex], so [tex]4<t<5[/tex].

So, the solution is [tex]\boxed{t=4.4594}[/tex] because it's the only answer that works.

Answer:

Smallest is 9 3/2 middle is 1/3 and biggest is 125 2/3

Step-by-step explanation:

It's pretty self explanatory. Try looking at the whole number first and then focusing on the fraction!

Hope that helped! Can I also get brainliest? I need a few more to advance, if not thank you anyways and have a nice day!!!

here. this should help

Answer:

Step-by-step explanation:

2500 +625+625+2500=6250

There are 6250 square feet inches total

625 square ft

625      = 1/10    {proportion}

6250

6000x 1/10

= 600

apportioned cost = {$600}

You can cross multiply for this problem. So:

[tex]\frac{6}{10}=\frac{21}{K}\\6K=210\\K=35[/tex]

So K=35!

Hope this helps! :)

Answer:

C

Step-by-step explanation:

i did it already

Answer:

C=3/2

Step-by-step explanation:

C4-1=5

Add 1 onto both sides

C4=6

Divide each side by 4

C=6/4

Simplify (Divide by 2)

C=3/2

Answer:

(Go with the melon, tomato, or pumpkin)

Step-by-step explanation:

MELON: I chose the melon. The target is 40ft away, so the maximum height of the launch has to be 12 feet.

TOMATO: I chose the tomato (because the numbers are round and easy to manipulate) The target is 60ft away, so the maximum height of the launch has to be 45 feet.

PUMPKIN: I chose the pumpkin. The target is 50 ft away, so the maximum height is 62 feet.

Step-by-step explanation:

the average rate of change between two input values is the total change of the function values (output values) divided by the change in the input values.

so,

(g(-3) - g(-9)) / (-3 - -9)

g(-3) = (-3)² + 10×-3 + 20 = 9 - 30 + 20 = -1

g(-9) = (-9)² + 10×-9 + 20 = 81 - 90 + 20 = 11

-3 - -9 = -3 + 9 = 6

(-1 - 11) / 6

-12/6 = -2

the average change rate in this interval is -2 (or fully -2/1).

Answer:

∆ACD≅∆BCD                              definition of a segment bisector

Step-by-step explanation:

I think this is the only way to prove it in one reason

If side JM = 30 and side LM = 8, the length of side KM is equal to 15.49 units.

In this exercise, we would assign the variable x to the length of side KM. Based on the information provided about triangle JKM and triangle KML, we can logically deduce the following parameters;

Side JL = [(30 + 8) × x]/2

Side JL = 38x/2

Side JL = 19x.

Since point M is the perpendicular bisector of both triangle JKM and triangle KML, the length of side KM can be calculated as follows;

19x = √[(30² + x²)(x² + 8²)]/2

38x = √[(30² + x²)(x² + 8²)]

By taking the square of both sides, we have:

38²x² = (900 + x²)(x² + 64)

38²x² = 900x² + 57,600 + x⁴ + 64x²

38²x² = 964x² + 57,600 + x⁴

(x² - 240)² = 0

x² = 240

x = √240

x = 15.49 units.

Answer:

[tex]s=-1[/tex]

Step-by-step explanation:

[tex]7=-10s-3[/tex]

[tex]-10s-3=7[/tex]

Add 3 to both sides:

[tex]-10s-3+3=7+3[/tex]

[tex]-10s=10[/tex]

Divide both sides by -10:

[tex]\frac{-10s}{-10}=\frac{10}{-10}[/tex]

[tex]s=-1[/tex]

Answer:

x = 3.5

x = 0.1

x = 4

x = 20

(In order top to bottom)

Step-by-step explanation:

2(x) = 7

/2     /2

x = 3.5 (1st one)

60(x) = 6

/60    /60

x = 0.1 (2nd one)

12(x)=48

/12    /12

x = 4 (3rd one)

1/20(x)=1

x20    x20

x = 20 (4th one)

Equations:

1. 2 • x = 7

2. 60 • x = 6

3. 12 • x = 48

4. x • 1 over 20 = 1

Value of x (Answers):

1. 3.5

2. 0.1

3. 4

4. 20

Explanations:

For number 1;

7 ÷ 2 = 3.5

3.5 • 2 = 7

Therefore, 3.5 is your answer for number 1.

For number 2;

6 ÷ 60 = 0.1

0.1 • 60 = 6

Therefore, 0.1 is your answer for number 2.

For number 3;

48 ÷ 12 = 4

4 • 12 = 48

Therefore, 4 is your answer for number 3.

For number 4;

1 over 20 = 0.05

1 ÷ (1 over 20) = 20

20 • 1 over 20 = 1

Therefore, 20 is your answer for number 4.

Hope I made it clear for you, have a nice day!!! (I'm sorry that I am 4 months late.)

Answer:

233.4 Centimeters

Step-by-step explanation:

48 x 10 = 480

48 x 4 = 192

480 + 192 = 672

139 x 10 = 1390

139 x 2 = 272

1390 + 272 = 1662

1662 + 672 = 2334

2334mm = 233.4cm
