Solve and explain please
1 answer:
Therefore the inequality is x≤11
and maximum I can withdraw 11 bills.
Step-by-step explanation:
Given ,
Current balance $320
Minimum balance $100
I could spent =$(320-100) = $220
Let the number of bills be x.
Total amount of x bills = $20x
According to the problem,
20x≤ 220
⇔x ≤
⇔x≤11
Therefore the inequality is x≤11
and maximum I can withdraw 11 bills.

The slope intercept form is
y=ax+b
So
11x-2y=-6 /+2y
11x=2y-6 /+6 both sides
11x+6=2y (changing sides)
2y=11x+6 /:2 divide by 2 both sides
y=
- its the result
y=ax+b
So
11x-2y=-6 /+2y
11x=2y-6 /+6 both sides
11x+6=2y (changing sides)
2y=11x+6 /:2 divide by 2 both sides
y=
