Answer:
The graph in the attached figure
Step-by-step explanation:
Let
x ----> the number of days
y ----> the amount of money in her bank account
we know that
The equation of the line in slope intercept form is equal to
where
m is the slope or rate
b is the y-intercept or initial value
In this problem we have
The slope is equal to
----> is negative because is a decreasing function
----> initial amount in the account bank
substitute
see the attached figure to better understand the problem
Answer:
The equations represent the situation is and
.
Step-by-step explanation:
Consider the provided information.
First convert the statement into mathematical representation.
Consider the smaller number is <em>x</em> and the larger number is <em>y</em>.
<em>y</em>, is equal to twice the sum of a smaller number and 3.
This information can be written as:
Which can be further solve as:
The larger number is also equal to 5 more than 3 times the smaller number.
This information can be written as:
Thus, the equations represent the situation is and
.
Which can be further solve as:
Now, substitute the value of <em>x</em> in .
