Answer: 8

Step-by-step explanation: In order to answer this question you start with the 85 shells that Lilly has in her collection, and then subtract the 13 shells that she gave away. 85 - 13 = 72, meaning that she has 72 shells left. Next, she divides the remaining 72 by 9, which will give you 8 groups. 72 / 9 = 8.

Answer:

she will have 8 groups of 9

Step-by-step explanation:

She gives 13 so 85-13 is 72 and 72 divided by 9 is 8

Does this graph show a function explain how you know
In-s [12.5K]
<h3>Answer:</h3>

C. No, the graph fails the vertical line test

<h3>Step-by-step explanation:</h3>

Functions describe the relationship between the dependent variable, y, and the independent variable, x.

Functions

For a graph to be a function, x-values cannot repeat. This means that one x-value cannot have more than one y-value.

However, functions can have repeating y-values. So, y-values can have more than one x-value; as seen in quadratic functions. This means that answer B cannot be correct.

Vertical Line Test

The vertical line test is a way to determine if a graph is a function. A graph passes the vertical line test if you can draw a vertical line at every point on the coordinate plane and not have it intersect with the graph more than once.

On the graph in the question, a vertical line would intersect with the graph twice at the x-values greater than -1. Since the graph fails the vertical line test, it is not a function.

If I flip a coin 56 times how many times will it land on heads I’d the probability is 1/2 or 50 present
aliya0001 [1]

Answer:

28

Step-by-step explanation:

So its a 50/50 chance for the coin to land on heads or tails, so we would divide 56 by 2

56/2 = 28

The polynomial p(x)=7^3-7x-6 has a known factor of (x+1) rewrite p(x) as a product of linear functions
san4es73 [151]

Answer:

p(x)=(x+1)(x+2)(x-3).

Step-by-step explanation:

Note: The given function is not correct.

Consider the given polynomial is

p(x)=x^3-7x-6

It is given that (x+1) is a factor of given function.

Using synthetic division, divide P(x) by (x+1) as shown below.

-1  |     1      0     -7      -6

    |           -1       1       6

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

        1       -1      -6       0

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

Bottom line represents the coefficients of quotient except the last element because it is remainder. So, the given function can be written as

p(x)=(x+1)(x^2-x-6)

p(x)=(x+1)(x^2-3x+2x-6)

p(x)=(x+1)(x(x-3)+2(x-3))

p(x)=(x+1)(x+2)(x-3)

Therefore, the function as a product of linear functions is p(x)=(x+1)(x+2)(x-3).
