Which set of ordered pairs represents a function? (1 point)
A) {(0, 1), (1, 3), (1, 5), (2, 8)}
B) {(0, 0), (1, 2), (2, 6), (2, 8)}
C) {(0, 0), (0, 2), (2, 0), (2, 4)}
D) {(0, 2), (1, 4), (2, 6), (3, 6)}

Answers

D.




Explanation: a function can be described as something that has only one output for each input. So an X or input can only have ONE output.


Ex. (2,6) (2,8) would NOT be a function because there are two 2’s with two different outputs meaning it’s not a function.
D because the pairs represent a function

A company sells two electronics packages. Package A contains 4 printers and 9 computers and costs $10,100 Package B contains 10 printers and 30 computers and costs $36,000

Answers

Answer:

y = $1433.33

x = -$700

Step-by-step explanation:

Since we are not asked what to find, we can as well find the price of each package.

Let x be the price of one printer

Let y be the price of one computer.

If Package A contains 4 printers and 9 computers and costs $10,100, this is expressed as;

4x + 9y = 10,100 ..... 1

If Package B contains 10 printers and 30 computers and costs $36,000, this is expressed as;

10x + 30y = 36,000

x + 3y = 3600 ...... 2

Solve equation 1 and 2 simultaneously

From 2; x = 3600 - 3y ..... 3

Substitute 3 into 1;

From 1;

4x + 9y = 10,000

4(3600-3y) + 9y = 10,100

14400 - 12y + 9y = 10100

14400 - 3y = 10100

-3y = 10100 - 14400

-3y = -4300

y = 4300/3

y = $1433.33

Substitute y = 1433.3 into 2;

From 2: x+3y = 3600

x + 3(1433.33) = 3600

x+4300 = 3600

x = 3600 - 4300

x = -$700

If DH = (4x + 10) in. and HI = (2x − 4) in., then x =_______ , HI =_______ , and ID = _________

Answers

i think the answer will be 6.

Answer:

x = -7

HI = -18

ID = -36

Step-by-step explanation:

I'm guessing that H is the midpoint, so that would mean DH = HI.

So plug in.

4x + 10 = 2x - 4 (subtract 2x on both sides)

2x + 10 = -4 (subtract 10 on both sides)

2x = -14 (divide by 2 on both sides)

x = -7

PLUG IN TO GET ID because DH + HI = ID

4(-7) + 10 + 2(-7) - 4 (simplify)

-28 + 10 -14 - 4 (collect like terms)

-46 + 10 = -36

ID = -36

HI = 2(-7) -4 (simplify)

HI = -14 -4

HI = -18

Hello!

[tex]\large\boxed{\text{n = 5, m = 9, x = 512}}[/tex]

An exponential expression in form [tex]\sqrt[z]{x^{y} }[/tex] can be rewritten as [tex]x^{\frac{y}{z} }[/tex] where "z" is the root and "y" is the power. For example:

[tex]x^{\frac{2}{3} } = \sqrt[3]{x^{2} }[/tex].

We can apply this idea to this problem:

[tex](32)^{\frac{9}{5} } = (\sqrt[5]{32^{9} } )[/tex]

Therefore:

n = 5

m = 9

Simplify the expression:

[tex]\sqrt[5]{32^{9} } = (\sqrt[5]{32} )^{9}[/tex]

[tex]\sqrt[5]{32} = 2\\\\2^{9} = 512[/tex]

Therefore, the values of all letters are:

n = 5

m = 9

x = 512

Answers

Answer:

option 3, 45

Step-by-step explanation:

3x - 9° + 30° + 24° = 180° (angle sum property of a triangle)

3x - 9° + 54° = 180°

3x + 45° = 180°

3x = 180° - 45°

3x = 135°

x = 135/3

x = 45°

therefore, option 3 is the correct option

Josh borrowed $50,000 from the bank to buy a new truck. The bank is going to charge him an interest rate of 6.9%. If his loan lasts 39 months, choose the correct equation to determine Josh's simple interest.

Answers

Answer:

The simple interest is $11,212.5 and the equation to determine Josh's simple interest is I = PRT/100

Step-by-step explanation:

The formula for calculating simple interest is expressed as;

SI = Principal * rate * time/100

SI = 50,000 * 6.9*39/100*12

SI = 500*6.9*39/12

SI = 134,550/12

SI = 11,212.5

Hence the simple interest is $11,212.5 and the equation to determine Josh's simple interest is I = PRT/100

P is the amount borrowed

R is the interest rate

T is the time in years

Which expression represents "4 times the sum of x and 7"

Answers

Answer:

4 (x + 7)

Step-by-step explanation:

Answer:

4(x+7)

Step-by-step explanation:

First, start with the terms x and 7, the expression calls for their sum so addition is the needed operation. Then, 4 times the sum means that 4 must be multiplied after x and 7 are added. So because of PEMDAS parentheses are needed around x+7. Therefore the expression is 4(x+7).

Charlotte's curtain company is making curtains for a local hotel. She wants each curtain to be 36 inches long. At the fabric store, fabric is sold by the foot. If Charlotte's curtain company wants to make 53 curtains, how many feet of fabric will she need?

Answers

Answer:

159 feet of fabric

Step-by-step explanation

We are told that 1 curtain is 36inches long

Since 1 foot = 12inches

x foot = 36inches

Cross multiply;

12 * x = 36

12x = 36

x = 36/12

x = 3

Hence 36inches is same as 3 feet

If Charlotte's curtain company wants to make 53 curtains, the length of 53 curtain is expressed as;

1 curtain = 3feet

53 curtain = y

y = 53 *3

y = 159 feet

Hence she will need 159 feet of fabric
