Write a direct variation equation if x = 7 and y = 42.

16.

Use the equation in example 15 to find x if y = 66.

**Answer:**

15. y = 6x

16. x = 11

**Step-by-step explanation:**

15. A direct variation equation is of the form ...

y = kx

Solving for k, we find ...

k = y/x = 42/7 = 6

**The equation is y = 6x**.

__

16. Filling in the given values, we have ...

66 = 6x

** 11 = x** . . . . . . . divide by 6

Victoria kicked a soccer ball laying on the ground. It was in the air for 5 seconds before it hit the ground. While the soccer ball was in the air, it reached a height of approximately 15 feet. Assuming that the soccer ball height (in feet) is a function of time (in seconds), what is the domain in the context of this problem?

**Answer:**

the Domain would be represented by Time in this problem, since time can only be positive, the domain would start at zero seconds and end at 5 seconds when the soccer ball hits the ground.

Can someone plz help me? I really don’t get this

**Answer:**

D.

**Step-by-step explanation:**

The question is asking which expressions are the same. To find the answer, or rather confirm it, you should simplify each expression.

A. 8+(3*y) and (8+3)*y

8+3y and 11y

This cannot be the answer, when simplified they are not equal

B. (7-3)*y and 7-(3*y)

4y and 7-3y

This cannot be the answer, when simplified they are not equal

C. (6/y)+13 and 13+(y/6)

13+6/y and y/6+13

This cannot be the answer, when simplified they are not equal

D. 7+(y*5) and 7+(5*y)

7+5y and 7+5y

This *is* the answer, when simplified they *are* equal

Margie says the set of numbers, 0. 1, -1, -21 4 , 3, are in order from least to greatest. What is her error? She did not use the correct common denominator. The 3 is in the wrong place. She treated all the numbers as positive. The â€"1 should be the first number on the list.

**Answer:**

3 is in the wrong place

**Step-by-step explanation:**

:)

One of the **errors **made by Margie by saying the set of **numbers** 0, 1, -1, -21, 4, 3 is that the -21 should be the **first number** on the list.

The **given set** of numbers is:

0, 1, -1, -21, 4, 3.

Margie says that the set of numbers above is in order from** least **to **greatest**

Kindly** note** that:

The **negative number** with the highest magnitude is the **lowest**

The** positive number **with the **highest magnitude** is the **highest**

**Arranging **this number by **carefully following** the note above, the set of numbers above from the **least to greatest** is:

-21, -1, 0, 1, 3, 4

It is obvious that Margie made a **mistake** in arranging the numbers, and one of the mistake is that the -**21 **should be the **first number** on the **list** since it is the **most negative**

What is the radius of a circle whose equation is x2 y2â’10x 6y 18=0? 2 units 4 units 8 units 16 units.

The **radius **of the **circle** is **4 units**.

Given to us:

[tex]x^2 + y^2 - 10x + 6y + 18 = 0[/tex]

The **generalized format** for **radius **of a **circle **is given by:

[tex]\\(x - h)^2 + (x - k)^2 = a^2\\where,\\h, k= coordinate\ of\ the\ center\ of\ the\ circle\\a= radius\ of\ the\ circle[/tex]

therefore after rearrangement of the equation we get,

[tex]x^2 + y^2 - 10x + 6y + 18 = 0,\\x^2 - 10x + y^2 + 6y =- 18,\\[/tex]

adding 25 and 9 on both the sides to bring it in the **generalized format for radius of a circle**,we get

[tex]x^2 - 10x+25 + y^2+ 6y+9 =-18+25+9,\\[/tex]

[tex](x - 5)^2 + (y + 3)^2 = 16\\(x - 5)^2 + (y + 3)^2 = 4^2\\[/tex]

Hence, the **coordinate **for this **circle **are x=5 and y=-3. And the **radius **of the **circle **is **4 units**.

**Answer:**

The parallelogram whose sides are 5 and 20 is similar

**Step-by-step explanation:**

The parallelogram whose sides are 5 and 20 is similar to the given parallelogram whose sides are 2 and 8 because the figures are the same shade and corresponding sides are proportional.

[tex]\frac{2}{5} = \frac{8}{20}[/tex] [tex]\frac{2}{4} \neq \frac{8}{18}[/tex]

What is the equation of the line that passes through the point (2,-2) and has a slope of -1/2?

**Answer:**

y = - [tex]\frac{1}{2}[/tex] x - 1

**Step-by-step explanation:**

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - [tex]\frac{1}{2}[/tex] , then

y = - [tex]\frac{1}{2}[/tex] x + c ← is the partial equation

To find c substitute (2, - 2 ) into the partial equation

- 2 = - 1 + c ⇒ c = - 2 + 1 = - 1

y = - [tex]\frac{1}{2}[/tex] x - 1 ← equation of line

**Answer:**

y=-1/2x-1

**Step-by-step explanation:**

y-y1=m(x-x1)

y-(-2)=-1/2(x-2)

y+2=-1/2(x-2)

y=-1/2x+2/2-2

y=-1/2x+1-2

y=-1/2x-1

Describe the end behavior of the function.

f(x)=3(1/5)^x-2

Answer:

The leading coefficient test requires a polynomial.

Not a polynomial

Step-by-step explanation:

**Answer:**

x → -∞, f(x) → ∞

x → ∞, f(x) → -2

**Step-by-step explanation:**

f(x) is an exponential function with a base less than 1. It represents decay, so will approach infinity as x approaches negative infinity. It will approach a horizontal asymptote for large positive x.

The -2 added to the exponential term moves the asymptote from y=0 to y=-2.

** x → -∞, f(x) → ∞**

** x → ∞, f(x) → -2**

Roger is paid $50 to sell videos of a play to an audience after the play is performed.

He also receives $2 for each video he sells. The equation E=50+2v

E=50+2v

models the amount of money Roger earns selling v videos. The play's audience consists of 230 people.

What is the practical range of the equation?

Question options:

The set of all even integers greater than or equal to 50 and less than or equal to 510

The set of all integers greater than or equal to 50 and less than or equal to 510

The set of all real numbers greater than 0 and less than 230

The set of all real numbers greater than 50

The set of all even integers greater than or equal to 50 and less than or equal to 510

In other words, [tex]0 \le E \le 510[/tex] where E is an even integer.

===========================================================

Explanation:

The domain is the set of allowed inputs, while the range is the set of allowed outputs. For now, let's focus on the domain.

In this case, the domain is the set of integers between 0 and 230. We're dealing with the set {0,1,2,..., 229, 230} to represent the possible number of people who bought the video.

Let's plug in the smallest item from the domain (v = 0).

E = 50+2v

E = 50+2*0

E = 50+0

E = 50

This matches with the fact Roger gets paid $50 even if he didn't sell anything. This is the flat up front fee he got.

Now let's plug in the largest value for v (230).

E = 50+2v

E = 50+2*230

E = 50+460

E = 510

This tells us that $510 is the most Roger can get from the audience of 230 people. This is assuming that each person buys only one copy.

So we can see that the range of E values spans from $0 to $510.

Furthermore, notice that 2 can be factored from 50+2v to get 2(25+v). This shows that the expression 50+2v is always even. Therefore, we must clarify that we're dealing with the set of **even numbers between 0 and 510**

In symbolic form, we'd say [tex]0\le E \le 510[/tex] where E is an even integer.

In roster form, the range of possible E values is {0, 2, 4, ..., 506, 508, 510}.

2.50-25-25=2.00-10 dimes = 1.00-4 0.25=0

so

10 dimes and 6 quarters.

**Answer:**

10 Dimes and 6 Quarters.

**Step-by-step explanation:**

**Important info:**

16 Coins

Total = $2.50

**Note:**

Dimes = 0.10 Cents

Quarters = 0.25 Cents

**Question to answer:**

How many of each type of coin does she have?

**Solution:**

10 Dimes = $1.00

6 Quarters = $1.50

$1.00+$1.50 = $2.50

Therefore 10 Dimes and 6 Quarters = $2.50 and = 16 Coin.

Solve the system you have written above.

The smaller number, y is

Calculator

**Answer:**

x = 56

y = 15

**Step-by-step explanation:**

"The sum of two numbers is 71."

x + y = 71

"The difference of the two numbers is 41."

x - y = 41

Solve the system:

From the first eq.

x = 71 - y

Replacing this value in the second eq.

(71-y) - y = 41

71 - 2y = 41

71 - 41 = 2y

30 = 2y

y = 30/2

y = 15

From the second eq.

x - y = 41

x - 15 = 41

x = 41 + 15

x = 56

Check:

from the first eq.

x + y = 71

56 + 15 = 71
