You first have to distribute the negative to the second pair of parenthesis. So the new equation would be 2n-4-4n+3. Next you combine like terms. So your final answer is -2n-1.
The rate of change is the same as the slope.
Let's find the slope of function 1 using the Rise Over Run rule.
The rise is 2 and run is 1. So your rate of change is 2/1 or 2 for function 1
Function 2 is a y = mx + b equation, the slope is usually "m" or before the x
y = 1/2x + 7
1/2 is your rate of change for function 2
X= # of adults
y= # of children
1326= 6x + 4y
289= x + y
We are going to do substitution.
x = 289-y
1326= 6(289-y) + 4y
1326= 1734 -6y + 4y
1326= 1734 + -2y
-408= -2y
204 = y
Since we now have a value for y, we should plug that back into the equation we got the x value from to find the actual numerical value of x.
289= x + y
289= x + 204
85= x
In conclusion, 85 adults and 204 adults went to the swimming pool.
