The table shows a function. Is the function linear or nonlinear?

x y

8 20

14 2

20 0

help!!

Answer:

a. The domain of the function is -3 < x ≤ 5

b. The range of the function is -3 ≤ y < 3

c. The y-intercept is the point (0, 0)

d. The values of 'x' at which f(x) ≥ 0 are;

x = -3, x = 1, x = 5

e. The intervals over which f(x) is decreasing are;

-3 < x ≤ - 1, and 1 ≤ x ≤ 3,

f. The local minimums are;

(-1, -1), and (3, -3)

Step-by-step explanation:

a. The domain of a function is the set of the possible independent variable values

Therefore, the domain of the function is -3 < x ≤ 5

b. The range of a function is the set of the possible values of the dependent variable

Therefore, the range of the function is -3 ≤ y < 3

c. The y-intercept is the point (0, 0)

d. The values of 'x' for which f(x) ≥ 0 are;

x = -3, x = 1, x = 5

The range of values of 'x' where f(x) ≥ 0 are;

-3 < x ≤ - 1.5, 0 ≤ x ≤ 1.5, 4.5 ≤ x ≤ 5

e. f(x) is decreasing over the following intervals;

-3 < x ≤ - 1, and 1 ≤ x ≤ 3,

f. The local minimums are the points that are lowest compared to other nearby points

The local minimums are;

(-1, -1), and (3, -3).

Answer:

See Explanation

Step-by-step explanation:

Given

[tex]Ladder = 9ft[/tex]

[tex]Tallest\ Sunflower = x[/tex]

Required

How much taller is the tallest

To get this, we simply calculate the difference between the height of the tallest sunflower and the ladder.

i.e.

[tex]Difference = Tallest\ Sunflower - Ladder[/tex]

[tex]Difference = x - 9[/tex]

-----------------------------------------------------------------------------------------------------

If for instance, the tallest is 13ft, then it is 4ft taller.

Because:

[tex]Difference = 13ft - 9ft[/tex]

[tex]Difference = 4ft[/tex]

Answer:

They need to sell more than 40 CDs to make a profit.

Explanation:

They will make a profit when the sales are higher than the cost and with the information provided, you can write the following inequality:

10x>300+2.5x, where x is the number of CDs sold

Now, you can solve for x:

10x-2.5x>300

7.5x>300

x>300/7.5

x>40

According to this, the answer is that they need to sell more than 40 CDs to make a profit.

Answer:

3 inches

Step-by-step explanation:

if she cut 3 inches off the length, that makes it 9 inches. the original rectangle was 2 inches longer. so subtract 2 from 9 and 7. she needs to have the width 7 inches.

Answer:

A) 180 square feet.

Step-by-step explanation:

The two rectangles are congruent, therefore having the same area.

The area of a rectangle, or any quadrilateral for that matter, is Length x Width.

12 * 4 = 48

There are two, so multiply this number by 2 and you get 96.

The formula for a trapezoid's area is height *  1/2 * (base 1 + base 2)

The height given is 6 feet. The 1st base is 10 feet, and the longer base is 10 + 4 + 4, this equals 18

The formula is now

[tex]6 * \frac{1}{2} (18 + 10)\\6 * \frac{1}{2} (28)\\6* 14\\=84[/tex]

Now in total, 84 + 96 = 180.

B is not the answer, A is.

Answer:

True!

Step-by-step explanation:

Put all the whole numbers together so 2+ (-2) cancels out

2-2+5x

positive 5x would be the only thing left so there you go!!!

Answer:

C. y=5x

Step-by-step explanation:

I'm pretty sure that it's y=5x, because it says that y represents the price, and that 2 represents that amount of board games. The price is $75, and the number of board games is 5. So the answer should be y=5x.

Answer:

The basketball volume is 1135.2 in³ greater than the soccer ball volume.

Step-by-step explanation:

Basketball volume is V = (4/3)πr³, or V = (4/3)(3.14)(10 in)³ = 4188.79 in³

Soccer ball volume is V = (4/3)πr³, or V = (4/3)(3.14)(9 in)³ = 3053.63 in³

Subtract the smaller from the larger to determine how much greater the large ball volume is:

4188.79 in³ - 3055.63 in³ = 1135.2 in³

Answer:

1135.2

Step-by-step explanation:

1135.2

Answer:

the answer is d.

Step-by-step explanation:

first, you want to use the formula,

new value - original value

____________________

         original value              * 100

you see that 84 is the new value and 79 would be the original value. substitute the numbers in. this is a increase since you will get a positive value.

84 - 79

______

   79      * 100

now we solve it.

5

__

79  * 100

you can either solve the fraction first then multiply that by 100 or multiply the numerator by 100 first then divide that by 79, each way works.

500

____

 79   =  approximately 6.3% increase (this is not a exact value, just rounded)

      or

5

__

79  = approximately 0.063 (this is not a exact value, just rounded)

0.063 * 100 = 6.3% increase

Answer:

x³- x²- 30x + 72

Step-by-step explanation:

this is just like simple multiplication, you need to multiply each term in (x + 6) by each term in (x² - 7x + 12)

Answer:

x= 2/3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

22−9x=9x+10

22+−9x=9x+10

−9x+22=9x+10

Step 2: Subtract 9x from both sides.

−9x+22−9x=9x+10−9x

−18x+22=10

Step 3: Subtract 22 from both sides.

−18x+22−22=10−22

−18x=−12

Step 4: Divide both sides by -18.

Answer:

y = 5/9x + 19/3

Step-by-step explanation:

slope: 10 - 5 / 6 - (-3) = 5/9

point-slope form:

y - 5 = 5/9(x + 3)

y -5 = 5/9x + 4/3

y = 5/9x + 6 1/3
