X = {(2, 3), (2, 4), (2, 5), (2, 6)} is x a function and why? no, each ordered pair in this list has the same first element. yes, no two ordered pairs in this list has the same second element. yes, there is more than one ordered pair in this list. no, there is a limited number of ordered pairs in this list.

Answers

Answer 1

Answer: for every input, there is one output
for every x there is one y
(x,y)

if x repeats with a differnt y, it's not a function
we see
(2,3) and (2,4) and all of them

no, not a function
no, each ordered pair in this list has the same first element
answer is first one

x=-1 to -7

Step-by-step explanation:

a washer and a dryer cost 659$ combined. The washer costs 91$ less than the dryer, how much was the dryer?

Answers

W+D=659

W=D-91

---------------------------

(D-91)+D=659

D-91+D=659

2D=750

D=750/2=375

------------------------------

W+375=659

W=284

------------------------------

So the dryer had cost $375 and the washer had cost $284.

a washer and a dryer cost 659$ combined. The washer costs 91$ less than the dryer, how much was the dryer?
washer --> x
dryer --> y

x + y = 659$
y = x + 91$

x + x + 91$ = 659$

2x = 659$ - 91$

2x = 568$ |:2

x = 284$
y = x + 91$ = 284$ + 91$ = 375$

The dryer costs 375$ and washer costs 284$

If h(x)=x-7 and g(x)=x^ which expression is equivalent to (g•h)(5)?A) (5-7)^
B) (5)^-7
C) (5)^ (5-7)
D) (5-7)x^

Answers

Answer:

A (5-7)^

Step-by-step explanation:

We have the next two functions h(x)=x-7 and g(x)=x^. We need to find (g•h) that is equal to g(h(x)) then:

(g•h)=g(h(x))=(x-7)^

Finally in the poin x=5 we have:

(g•h)=g(h(x))=(x-7)^

(g•h)=g(h(5))=(5-7)^

Then the answer is A

Assuming that by ^, you mean ², here's how you do this:
(g•h)(5) means that you need to solve g(h(5)). So, you plug 5 in for x in h(x), then you plug the solution of that in for x in g(x) like so:
$h(5)=5-7 \n g(h(5))= (5-7)^(2)$

The answer is A. (5-7)²

What is the angle supplementary to the angle measuring 165°12′?A. 75°12′
B. 180′
C. 14°48′
D. 60′

Answers

Two angles are supplementary if their sum is 180 degrees. One degree is made up of 60 minutes. So the angle supplementary to an angle measuring 165d12m is 180d - 165d12m, which gives us 14d48m. So the answer is C.

Answer:

Option C is correct.

$14^(\circ)48'$ is the angle supplementary to the angle measuring $165^(\circ)12'$

Step-by-step explanation:

To find the angle supplementary to the angle measuring $165^(\circ)12'$

Let A be the angle supplementary to the angle measuring $165^(\circ)12'$ .

Supplementary Angles states that the two Angles are Supplementary when they add up to 180 degrees.

Use the conversion:

1 degree = 60 minute.

Then, we have the given angle $165^(\circ)12'$ = $165(12)/(60) =165(1)/(5) =165.2^(\circ)$

Now, by definition of supplementary angle;

$\angle A + 165.2^(\circ)= 180^(\circ)$

Subtract 165.2 on both sides we get;

$\angle A= 180^(\circ) - 165.2^(\circ) =14.8^(\circ) =14^(\circ)48'$

Therefore, the angle supplementary to the angle measuring $165^(\circ)12'$ is, $14^(\circ)48'$
