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:
91
Step-by-step explanation:
Substitute 4 in place of x
f(4)=20*4+11
f(4)=80+11
f(4)=91
Slope-intercept form: y = mx + b
m = the slope
b = y-intercept.
In this problem,
m = 3/5
b = ?
So far y = 3/5x + b
Let's plug the point (-3, -1) into our slope equation.
-1 = 3/5(-3) + b
Simplify the right side.
-1 = -9/5 + b
Add 9/5 to both sides.
4/5 = b
The equation is: y = 3/5x + 4/5
Answer choice A is correct.
2^5/2^2 = 2^(5-2)
= 2^3
= 8
