The answer is B.

The reason why is because for it to be a function none of the x’s can repeat.
None of the x’s in choice be repeat.

Answer: the awnser is 9, 40, 41 mark me brainlist

Step-by-step explanation:

Sum of the squares of the two side  = Square of longest side

a² + b² = c²

a)

So let's check 7, 24, 25

Is 7² + 24² = 25²  ?

7*7 + 24*24

49 + 576 

=625.

Let us perform the other side 25²

25² = 25 * 25 = 625

Therefore the left hand side = Right hand side.

Therefore 7, 24, 25 is a Pythagorean Triple

b)

Let's check 9, 40, 41

Is 9² + 40² = 41²  ?

9² + 40²

9*9+ 40*40 

81 + 1600

=1681

Let us perform the other side 41²

41² = 41 * 41 = 1681

Therefore the left hand side = Right hand side.

Therefore 9, 40, 41 is a Pythagorean Triple.

A student says that the algebraic expression 5 x 7 can also be written as 5 7x. is the student correct? explain.
ohaa [14]
Nahhhh
So basically WHERE DID THE x COME FROM anyway ??? 
5 * 7 = 35
but
IT DOES NOT EQUAL TO
57x
It might be true depending on what the x value is, but you dont know what the x value is so ...

X over 45 - 7 over 9. X = ?
Degger [83]

Answer:

X=35

Step-by-step explanation:

simplify 7/9

x/45-7/9=0

simplify x/45

x - (7 • 5)/45=  x - 35/45

x-35/45=0

add 35  to both sides

x=35

I tried it's hard to write it all out on here i just to give u the best sorry :)

Write the interval using interval notation to describe the set of values shown above.
jenyasd209 [6]

The interval on the number line is (-∞, 2) U [3, ∞)

<h3>How to determine the interval?</h3>

From the number line, we have the following inequalities

x < 2 and x ≥ 3

In inequalities, < and > are represented by brackets i.e. ( and )

While ≤ and ≥ are represented by square brackets i.e. [ and ]

So, we have:

x < 2 and x ≥ 3 = 2) and [3

The intervals must be closed and opened with infinity symbols.

So, we have:

x < 2 and x ≥ 3 = (-∞, 2) and [3, ∞)

Replace and with U

x < 2 and x ≥ 3 = (-∞, 2) U [3, ∞)

Hence, the interval on the number line is (-∞, 2) U [3, ∞)
