Answer:

The completed ordered pair are;

(0, 1), (-1, -1), and (1, 3)

Step-by-step explanation:

The ordered pair, (x, y), presents the corresponding values of 'x' and 'y' based on a given relationship, or equation

The given relationship between 'x', and 'y' is, y = 2·x + 1

Therefore, given that the x-values (first of two values, separated by the coma) are given, we have;

In the given incomplete pair (0, ), when x = 0, therefore, y = 2 × 0 + 1 = 1

The complete ordered pair is (0, 1)

Similarly, for (-1, ), we have;

When x = -1, y = 2 × (-1) + 1 = -1

The complete ordered pair is (-1, -1)

We also have for the incomplete pair, (1, )

When x = 1, y = 2 × 1 + 1 = 3

The complete ordered pair is (1, 3)

The completed ordered pair for the equation, y = 2·x + 1, are therefore;

(0, 1), (-1, -1), and (1, 3).

olchik [2.2K]

Answer:

a)E=.05t +34

b)$54

c)$600

Step-by-step explanation:

a) he gets 5% of tips out of all tips people gave to the restaurant , 5% --> .05 (as a decimal) --> this is "t"

he earns an extra $34 a night of work. --> this is the constant

E= --> the total earned that night

E=.05t +34

b) simply plug in the total tip into the equation

E=.05(400) + 34

E=$54

--> he earned $54 that night

c) since we are given the total earned that night, we now plug in for y. in this case we plug "$64" for y

we find t, which is tip the restaurant was given

--> 64 = .05t +34

-34. -34

30= .05t ---> divide by .05 each side

t= $600

the restaurant was tiped 600 dollars and Alun was paid 64 dollars that night of work

hoped this helped:)

I need help on writing fractions into simplest form

mojhsa [17]

Hi!

Is there a specific question you need help with? Writing fractions into simplest form is very easy. All you have to do is find a number that both the numerator and denominator can be divided by, and divide them both with it.

For example: 15/20. They both can be divided by 5. So do that. 15 divided by 5 = 3. 20 divided by 5 = 4. So the new fraction will be 3/4. It cannot be divided by another whole number. So that is the simplest form.

Pls let me know if you need more help.

Have a great day!

Rewrite each expression in factored form using the greatest common factor. 11. 16x+48 12. 28x+ 32y 13. 11w+hw pls help!!!

34kurt

Answer:

16(x + 3)

4(7x + 8y)

w(11 + h)

Step-by-step explanation:

16x + 48

The greatest common factor of 16 and 48 = 16

Hence, expressing 16x + 48 in factored form:

16x + 48 = 16(x + 3)

28x + 32y

Greatest common factor of 28 and 32 = 4

Hence,

28x + 32y = 4(7x + 8y)

11w + hw

11w + hw = w(11 + h)

Suppose there are 20 people in a room and the mean amount of cash held by these 20 people is $14.50 per person. If two people en

leva [86]

Answer:

13.59

Step-by-step explanation:

The calculation of amount of cash in the room is shown below:-

$\$14.50 = \frac{\Sigma xi}{20}$

= 20 × $14.50

= $290

Now, the new sum is

= ∑xi + $4.00 + $5.00

= $290 + $4.00 + $5.00

= $299

Total person in the room is

= 20 + 2

= 22

So,

Mean amount of cash in the room = New sum ÷ Total person in the room

= $299 ÷ 22

= 13.59
