Hello from MrBillDoesMath!
Answer:
Suppose the ordered pair is (x.y). Substitute these values in the linear equality to see if it is true,
Example. Consider the point (7, -4). Is it a solution of the linear inequality
3x < 4y - 9? Let's check to find out.
Check:
Is 3 (7) < 4 (-4) - 9 true ?
Is 21 < -16 -9 = -25 ??
NO!
So (7,-4) is NOT a solution of the linear inequality.
Thank you,
MrB

Answer:
80n+20=total cost
Step-by-step explanation:
We don't know the value of n, but we don't need it for an expression. We know that the family has to pay $80 per night that they stay at the hotel. Modeling this would look like: 80n (80*n for nights). Also, we know that the family MUST pay a $20 fee. So, we can add that on to the expression to look like this, 80n+20=total cost.
Hope this helps!
Have a nice evening.
