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:
1. (x - 5), (x + 1)
2. (x + 5), (x -2)
Step-by-step explanation:
1. x^2 - 4x -5
Find two numbers that both multiple to -5 and add to -4 (-5 and 1)
(x - 5), (x + 1)
2. x^2 - 3x - 10
--same concept for these question
What two numbers multiple to equal -10 and add to equal 3?
5 and -2
(x + 5), (x - 2)
Answer:
Ah I see it's the same it's a little more complex but I can do this as well.
But I can't type bcoz it will make it slow
so I'll write for this.ß
