Answer:
Step-by-step explanation:
Given
Required
Represent using an inequality and solve
Let the number of dollars be represented by n
<em>If 1 withdrawal is $20 bill</em>
<em>n withdrawals would be $20n bills</em>
The total withdrawal and the minimum balance must be less than or equal to the available balance.
So, this gives
Substitute values for each of these
Solving for n
Divide through by 20
But n can not be decimal because it represents number of dollar bills , which must always be an integer.
So, we round down the value of n
Answer: y = 4x-1
Step-by-step explanation:
1) Choose two points for the later equation.
For this example, I will use (-1,-5) and (2,7)
2) Place it in a rise/run equation. (y/x)
The Slope is 4.
3) Find the y-intercept
So, we can place a given point and slope into a y=mx+b function.
Next, we can substitute the point and slope.
4) Finally, place it all in slope intercept form
y = 4x-1
