What are the instructions or equations to use
Answer:
x^2 + 2x + 1
Step-by-step explanation:
1. collect the like terms.
2. use the commutative property to reorder the terms.
Answer:
Its 22
Step-by-step explanation:
x is 19
so 3+19 is 22
Answer:
C = 0.175x + 5
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
<em>A phone company has a monthly cellular data plan where a customer pays a flat monthly fee $5 and then a certain amount of money per megabyte (MB) of data used on the phone</em>
Given:
- Customer uses 80 MB
- The monthly cost will be $19.00 (flat monthly fee and then a certain amount of money per megabyte (MB) of data used on the phone)
So let:
- C is the cost of the data plan
- x is amount of money per megabyte (MB)
We can form the standard equation:
C = mx + b <=> C = mx + 5
In this situation, we have:
19 = m*80 + 5
<=> m = 0.175
So the a linear equation is: C = 0.175x + 5
Hope it will find you well
The function represented by the table is given by the rate of change of
the <em>x</em> and y-values which are constant indicating a linear function.
Response:
The statement that could be used to justify that the table represents a linear function is as following;
- The y-values decrease by the same amount
<h3>How to determine if a table represents a linear function?</h3>
The table of of a linear function is one in which the first difference in
the y-values is constant given that the difference in the x-values are also
constant.
From the table, the first difference between each y-value and the
previous y-value is found as follows;
20 - 35 = -15
5 - 20 = -15
-10 - 5 = -15
While the difference between the corresponding x-values = 1 as follows;
0 - (-1) = 1
1 - 0 = 1
2 - 1 = 1
Therefore;
The (rate of) change in the <em>x</em> and <em>y</em> -values in the table are constant, and
the function is a linear function.
The correct statement is therefore;
- The y-values decrease by the same amount
