The set of ordered pairs below represents a function.

Josiah claims that the ordered pair (6, –10) can be replaced with any ordered pair and the set will still represent a function.

Select all ordered pairs that could be used to show that this claim is incorrect.
(–9, –6)

Answers

Given:

The set of ordered pairs below represents a function.

{(–9, 1), (–5, 2), (0, 7), (1, 3), (6, –10)}

Josiah claims that the ordered pair (6, –10) can be replaced with any ordered pair and the set will still represent a function.

To find:

All the ordered pairs that could be used to show that this claim is incorrect.

Solution:

We need to find the ordered pairs that can be replaced with (6,-10) and for which the set is not a function.

A relation is called function if there exist a unique output for each input.

If (-9,-6) is replaces with (6,-10), then the set has two outputs y=1 and y=-6 for x=-9. So, the claim is incorrect.

If (1,12) is replaces with (6,-10), then the set has two outputs y=12 and y=3 for x=1. So, the claim is incorrect.

If (-10,-10) is replaces with (6,-10), then there exist unique output for each input. So, the claim is correct.

If (4,7) is replaces with (6,-10), then there exist unique output for each input. So, the claim is correct.

If (-5,1) is replaces with (6,-10), then the set has two outputs y=1 and y=2 for x=-5. So, the claim is incorrect.

Therefore, the correct options are (a), (b) and (e).

y=9(2x)


y=(5x+3)2


y=8x2


y=5x−3


y=3x2+2x−1

Answers

Answer:

liner Y=9(2x)  Y=5x-3

Step-by-step explanation:

The equations which are linear are

a) y = 9( 2x )

b) y = ( 5x + 3 )2

d) y = 5x - 3

The equations which are non linear are

c) y = 8x²

e) y = 3x² + 2x - 1

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

a)

Let the equation be y = 9( 2x )

Now , on simplifying the equation , we get

y = 18x

Now , this is a linear equation in 2 variables of the from y = mx + c

So , the equation is linear

b)

Let the equation be y = ( 5x + 3 )2

Now , on simplifying the equation , we get

y = 10x + 6

Now , this is a linear equation in 2 variables of the from y = mx + c

So , the equation is linear

c)

Let the equation be y = 8x²

Now , on simplifying the equation , we get

y = 8x²

This is a quadratic equation , and is not linear

So , the equation is non linear

d)

Let the equation be y = 5x - 3

Now , on simplifying the equation , we get

y = 5x - 3

Now , this is a linear equation in 2 variables of the from y = mx + c

So , the equation is linear

e)

Let the equation be y = 3x² + 2x - 1

Now , on simplifying the equation , we get

y = 3x² + 2x - 1

This is a quadratic equation , and is not linear

So , the equation is non linear

Hence ,

The equations which are linear are y = 9( 2x ) , y = ( 5x + 3 )2 and y = 5x - 3

The equations which are non linear are y = 8x² and y = 3x² + 2x - 1

John bought 12 items from the concession stand. He bought cokes and nachos for his friends. Cokes cost $2.50 each and Nachos cost $3.50 each. He spent a total of $37. How many Nachos did he buy?

Answers

Answer: He bought 7 nachos.

Step-by-step explanation:

Let x= Number of cokes

y = Number of nachos

As per given , we have

x+y=12     (i)

2.50x+3.50y=37    (ii)

Multiply 2.5 on both sides of (i), we get

2.5x+2.5y= 30      (iii)

Subtract (iii) from (ii), we get

y=7      (iv)

Put value of y from (iv) in (i), we get

x+7=12

⇒ x= 12-7

⇒ x=5

Hence, he bought 5 cokes and 7 nachos.
