Answer:
The equation that can be used to represent the total number of collector's card Stacy has in 'x' weeks is .
y = 3 + 2x
Completed question;
Stacy has 3 collector's cards. She receives 2 more cards each week that she volunteers at the student center. Let x = the number of weeks. Let y = the number of collector's cards. Write the equation that can be used to represent the total number of collector's card Stacy has in 'x' weeks.
Step-by-step explanation:
Given:
The number of cards she have initially = 3
The number of cards receive every week = 2
the number of week = x
the total number of collector's card after x weeks = y
The total number of collector's card will be equal to sum of the number of cards she had initially and the number of cards receive every week multiplied by number of weeks.
This can be written as;
y = 3 + 2x
Since there is no more details given in question as to what to derive;
we can conclude that;
The equation that can be used to represent the total number of collector's card Stacy has in 'x' weeks is .
y = 3 + 2x
In case any of the variables is given, simple substitution can be used to derive the other variable.
Answer:
h > 5
h < 0
Step-by-step explanation:
We suppose that a "Special Solution" inequality is one that is technically incorrect, but is written using a compact "shorthand" form.
As written, the inequality claims that 17 < 2, which is false. There can be no value of the variable that will make this true. We presume the intended meaning is ...
17 < 3h +2 <u>or</u> 3h +2 < 2
<h3>Special solution</h3>
Subtracting 2 from the inequality gives ...
15 < 3h < 0
Dividing by 3 gives ...
5 < h < 0
There is no value of h that is both greater than 5 and less than 0, so we presume this means the OR (union) of the solution sets ...
h > 5
h < 0
