Answer 1
Answer:

Answer:

d. Set A and Set B

Step-by-step explanation:

We have been given three sets:

Set A: (5, 2), (4, 3), (3, 4), (2, 5)

Set B: (-1, -6), (0, 2), (1, 2), (3, 6)

Set C: (2, 1), (4, 2), (2, 3), (8, 4)

Now we need to state about which of the following sets of ordered pairs represent a function.

We know that a function can't have repeated values in domain that is x-value can't repeat.

we see that set C has repeated x-value "2".

Then set C is not a function.

Hence correct choice is:

d. Set A and Set B
Answer 2
Answer:

Answer:

A and B represent functions.

Step-by-step explanation:

In a function, any input (x-) value may have only one associated y value.  If the same input appears more than once, we know immediately that the data do not represent a function.

A:  The inputs are unique:  {5, 4, 3, 2} so this is a function.

B:   The inputs are unique:  {-1, 0, 1, 3}, so this is a function.

C:   2 is used twice as input, so this is not a function.

Quinn needs to buy fabric for a border to sew onto all four edges of a tablecloth. He also needs an extra 0.875 feet of fabric to make a matching potholder. The length of the table cloth is 4/3 of its width (w) in feet. The total amount of fabric needed (f), in feet, is represented by the equation below. f=2 (w+4/3 w) + 0.875
Quinn needs 113/8 feet of fabric for the border of the tablecloth and the potholder. What is the width of Quinn's tablecloth?

Answers

The width of Quinn's tablecloth is 2.839 inch

Quinn needs to buy fabric for a border to sew onto all four edges of a tablecloth.

\rm Total \; amount \; of \; fabric\; needed \; f = 2(w+ (4)/(3)* w )+ 0.875.......(1) \n

\rm Length \; of\; tablecloth = L = (4)/(3) * w

According to the given condition the fabric required for potholder = 0.875 feet

Quinn needs 113/8 feet of fabric for the border of the tablecloth and the potholder.

The Total amount of fabric needed for the border and the potholder = 113/8.....(2)

So from equation (1) and (2)  we get

\rm f = (113)/(8) \n

\rm Total \; amount \; of \; fabric\; needed \; f = 2(w+ (4)/(3)* w )+ 0.875=(113)/(8) \n

Solving for w we can get

w = 2.839 inch

 

The width of Quinn's tablecloth is 2.839 inch

3 4/9 as a improper fraction

Answers

First, you do the denominator times he whole number

9 x 3 = 27

Second, you add the total you got to the numerator 

27 + 4 = 31

Third, Solve!

31/9 will be your answer 

The improper fraction of 3(4)/(9) is 31/9

The given expression is,

3(4)/(9)

We have to write it into improper fractions,

Since we know that,

An improper fraction, such as 6/5 and 12/5, is one in which the numerator is higher than or bigger than the denominator. Compared to other types of fractions like mixed fractions, improper fractions are simpler to solve using addition and subtraction.

Now to convert it into improper fraction

Multiply 3 with 9 then add it with 4 which gives the numerator,

Therefore,

3(4)/(9) = ((27 + 4 ))/(9)

    = 31/9

Hence,

3(4)/(9) = 31/9

How do I solve system of equations by substitution
y=-2x+2
y=7x+11

Answers

Answer:

(-1, 4)

Step-by-step explanation:

We are told that:

y = -2x + 2 and

y = 7x + 11.

We can eliminate "y" by setting these two equations = to each other:

-2x + 2 = 7x + 11.

We need to solve this equation for x.

Adding 2x to both sides, we get 2 = 9x + 11.

Subtracting 11 from both sides results in -9 = 9x.  Thus, x = -1.

Find y by subbing -1 for x in either of the given equations.

If we use the 2nd equation, then y = 7(-1) + 11, or y = 11-7, or y = 4.

The solution of this system of linear equations is (-1, 4)
