Which numbers are perfect squares? Check all that apply. 02 016 018 032 0 044 094 100​
Harman [31]

Answer:

16, 100

Step-by-step explanation:

A perfect square is a number that can be achieved by multiplying a number by itself.

Example: 100 = 10 x 10, so it is a perfect square

2 is not a perfect square because it has no factors that can be multiplied with each other to equal 2. An easy way to check is to use the square root function on your calculator.

If the result is a whole number then it's a perfect square.

Which of these graphs represents a function​
sveticcg [70]

Answer: Answer X

Step-by-step explanation:

In order for a graph to represent a function, it must pass the vertical line test. This means, if you were to draw a vertical line at ANY point along the graph, it should not intersect more than one point. For answers W, Y, and Z, they clearly fail the vertical line test. Answer X is the only graph that passes the vertical line test.

In the function f(x) = 6x + b, what must be the value of b, if f(5) = 1?
Brut [27]
<h3>Answer:    -29</h3>

=============================================

Work Shown:

f(x) = 6x + b

f(5) = 6(5) + b .... replace every x with 5

f(5) = 30 + b

1 = 30 + b ..... replace f(5) with 1, since f(5) = 1 was given.

1-30 = 30 + b - 30 .... subtract 30 from both sides

-29 = b

b = -29

-----------

The function f(x) = 6x+b turns into f(x) = 6x+(-29) which is equivalent to f(x) = 6x-29

Plugging in x = 5 leads to

f(x) = 6x-29

f(5) = 6(5) - 29

f(5) = 30 - 29

f(5) = 1

So we have confirmed the answer.
