Answer:
area 1
Step-by-step explanation:
The system of equations can be used to find the cost of a night's stay and the cost of a meal is:
2n + 5m = $395
5n + 11m = $959
<h3>
Simultaneous equations</h3>
Simultaneous equations are two or more groups of equations. These equations have to be solved together at the same time in order to determined the required valued. The two above equations have to be solved in order to determine the cost of a night's stay and the cost of a meal.
The methods of determining the required values are:
- Elimination method
- Graph method
- Substitution method

Answer:
I think B
Step-by-step explanation:
because their age group is 20-25 more of a constant age group
compared to 20-30
There are three steps
1 rearrange the equation so "y" is on the left and everything else is on the right
2 plot the "y=" line (make it a solid line for y< or y> and a dashed line for y< or y>)
3 shade above the line for a "greater than" (y> or y>) line under that or below the line for a less than (y< or y< line under it)
I know I got the last one wrong, so I will hopefully get this one right
I am not that great with Proportional and Not Proportional, but
1. Y is 0.5 times x
2. Y is 1.5 times x
