Easy Math - Lots Of Points

Answers

Answer 1

Answer:

a=-5, k=31

Step-by-step explanation:

Determine a and k so the given points are on the graph of the function:

(1,11) (2,-14)

[tex]y=a(x+1)^2+k[/tex]

To find the required values, we substitute the points into the equation:

[tex]11=a(1+1)^2+k[/tex]

[tex]-14=a(2+1)^2+k[/tex]

Operating:

[tex]11=a(2)^2+k[/tex]

[tex]-14=a(3)^2+k[/tex]

Simplifying:

[tex]11=4a+k[/tex]

[tex]-14=9a+k[/tex]

Subtract the second equation from the first equation:

[tex]11+14=4a-9a[/tex]

Simplifying:

[tex]25=-5a[/tex]

Solving:

[tex]a=25/(-5)=-5[/tex]

a=-5

Use this equation to find k:

[tex]11=4a+k[/tex]

[tex]11=4(-5)+k[/tex]

[tex]11=-20+k[/tex]

k=31

a=-5, k=31

Answer 2

Answer:

a = -5

k = 31

6x + 2 = 5x + 17, would there be one unique solution? What is it?

Answers

Answer:

X = 15

Step-by-step explanation:

1.- Rewrite the equation, Put like terms on the same side

6x - 5x = 2 - 17

Instead of adding subtract

2.- Divide 1 on both sides

1x = 15

You should only have X on the left side

3.- You should have

X = 15

Fit-quest charges a one-time registration fee of $50 plus $5 per fitness class. Fitnasium charges no registration fee, but charges $8 per fitness class. For how many fitness classes does Fitnasium cost less than or the same as Fit-quest?

Answers

50 + (5×16) 8×16

50 + 80 128

130. 128.

if she goes to gitnasium 1 more time then it eould be more than Fit-Quest.

16 of the fitness classes do Fitnasium cost less than or the same as Fit-quest.

What are Arithmetic operations?

Arithmetic operations can also be specified by the addition, subtract, divide, and multiply built-in functions.

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

/ Division operation: Divides left-hand operand by right-hand operand

For example 4/2 = 2

We have been given that Fit-quest charges a one-time registration fee of $50 plus $5 per fitness class. Fitnasium charges no registration fee, but charges $8 per fitness class.

Let the number of classes would be x

⇒ 50 + (5x) = 8x

Rearrange the terms of x in the above equation,

⇒ 8x - 5x = 50

⇒ 3x = 50

⇒ x = 50/3

Apply the division operation,

⇒ x = 16

Therefore, 16 of the fitness classes do Fitnasium cost less than or the same as Fit-quest.

Determine the constant of variation for the direct variation given.
R varies directly with S. When S is 16, R is 80.
1/5

16

Answers

Answer:

The constant of variation is k=5

Step-by-step explanation:

Proportions

A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:

[tex]y=k\cdot x[/tex]

Where k is the constant of proportionality.

We know R varies directly with S. Their relationship is:

[tex]R=k\cdot S[/tex]

We also have when S=16, R=80. Thus:

[tex]80=k\cdot 16[/tex]

Solving for k:

[tex]k=80/16=5[/tex]

The constant of variation is k=5

Solve for x.

x/2≥−4

this is an inequality, could you explain as well? will give out brainliest answer :)

Answers

Answer:

x≥-8

Step-by-step explanation:

Let's do this step by step:

Step 1-

Take x/2≥-4. Now multiply both sides by 2 to isolate the x variable. Multiplying x/2 by 2 removes the denominator.

Step 2-

Since we are multiplying both sides by 2, we also have to multiply -4 by 2. We get -8

Step 3-

Therefore, x≥-8

The difference of twice a number and 3 is at most -21

Answers

Answer:

The equation: 2n - 3 ≤ -21

The answer to the equation: n ≤ 9

Step-by-step explanation:

How to get the equation:

The difference of symbolizes subtraction. Because we are subtracting twice a number and 3, the first part of the equation can be written as 2n - 3. The n symbolizes the number.

is at most symbolizes a less than or equal to sign. That sign is ≤. And what is it less than or equal to? -21.

Now are equation is 2n - 3 ≤ -21

How to solve it:

2n - 3 ≤ -21

Add 3 to both sides of the equation

2n ≤ 18

Divide both sides of the equation by 2

n ≤ 9

Cast:JEANNETTE KENNETH DADMOM(Setting: The Washington familys kitchen)JEANNETTE: Ive perused this bevy of travel pamphlets and I have no inkling of where I want to go on vacation. I thought about attending a performance at the citys amphitheater; however, the city will be in bedlam with the performance and the sporting event occurring simultaneously. MOM: I didnt find a worthwhile destination either. KENNETH: Ive concluded that we should embark on an exhilarating and exciting trip this yearsomething weve never done before. MOM: I dont want to dismiss your idea, Kenneth, but where can find such an awe-inspiring experience? KENNETH: I thought we could hike up Mount Whitneyits the highest peak in California. Because its located on the border of Inyo and Tulare counties, its also relatively close to home. Since were all strong athletes, I think that making the ascent is feasible. JEANNETTE: (to Kenneth) That sounds like an awesome and memorable trip; however, theres one problem with your planI suffer from acrophobia. KENNETH: (with a look of befuddlement) Acro- what? MOM: Acrophobiait means that Jeannette suffers from a fear of heights. The root word phobia, meaning fear of, comes from the Greek word phobos, which means fearing. Acrophobia is one of the most prevalent phobias in the country.KENNETH: (to Jeannette) I recall a few years ago when we traveled on an airplane to Aunt Janices houseyou were enthralled, peering out the window at the scene below.JEANNETTE: I did have a tremendous time on the airplane; however, after that trip, my phobia gradually progressed, and now merely thinking about flying evokes terror and makes me squeamish. For me, riding the elevator to the top floor of a tall building is much like trekking up Mount Everestits a gigantic feat of willpower. MOM: Sometimes the best way to get over a fear is to face it. Perhaps we should try to climb the mountain so that Jeannette can tackle her fear. Do you think it would intolerable for you, Jeannette?JEANNETTE: (with a look of trepidation) I dont believe I would be very excited during the ascent, and I may not reach the apex; yet, I would savor the astonishing panoramic views. But what if I lost my composure and chose not to climb with you? I would be loath to jeopardize your trip. DAD: Jeannette, were a family; we must always support each other. I believe that if youre brave enough to attempt the climb, we should be more than willing to stop if you feel overwhelmed or extremely uneasy. MOM: Just trying is an immeasurable accomplishment! KENNETH: Ill have a wonderful vacation as long as I get to view the noteworthy peak; everything else is secondary to me. Whats your verdict, Jeannette?JEANNETTE: The thought of scaling a gigantic mountain is both scary and exhilarating. I must admit, the allure of Mount Whitney seems to trump my trepidation, and it would be incredible to overcome my fear. So, I suppose there is only one thing left to dopack!)

Parkour is thought by many to be an extreme sportespecially when people see parkour practitioners (known as traceurs) climbing walls and jumping off buildings. However, it might be better to characterize parkour as a radical art form involving both the body and mind. Although this art form can be extreme, it does not involve the teamwork, structure, or competitiveness of organized sports. In addition, traceurs can be difficult to recognize, as they do not wear matching uniforms to identify themselves. Parkour and its practitioners are in a category of their own. The ultimate goal of parkour is for a person to mentally and physically prepare to overcome any obstacle he or she may face. Traceurs, who pit their bodies against various types of obstacles, often risk physical injury, and safety is an important concern. While practicing parkour, a traceur's route may take him or her over a large boulder, across several rooftops, or across the top of a wall. As dangerous as these acts may sound, most traceurs do attempt to learn the safest way to move, jump, and land. Parkour has become a popular art form in urban settings around the world due to the many obstacles located around the cityscape. This has led to concerns for traceurs' safety, as well as worries about traceurs trespassing on private property and attempting to jump from high buildings. As in most physical activities, safety for oneself and others should be paramount in the practice of parkour. Which sentence from the passage best expresses the main idea of paragraph 2? A. "Parkour has become a popular art form in many cities around the world due to the many obstacles located around urban settings." B. "Traceurs, who pit their bodies against various types of obstacles, often risk physical injury, and safety is an important concern." C.
