Answer:
y = (10x + 600)/x
Step-by-step explanation:
To find the average cost, we must divide the total cost by the number of people.
The number of meals served will equal the number of people, since everybody gets just 1 meal.
Each meal is 10 dollars, plus the 600 rental fee.
The total cost will be the meal prices plus the fee, all divided by the number of people/number of meals, or x.
Point slope formula is y= mx+b. To find the slope, or m, you need to find the "rise over run". rise = y coordinates, run = x coordinates. And the slope equation is y1-y2/x1-x2. So let's say the first point is (x1,y1) and the second is (x2,y2). that would be 35-(-31)/5-(-6)= 66/11 or 6/1 aka up six, across one. That is your slope. So far you have y=6x+b, next plug (5,35) into that equation and solve for b (aka the y intercept). So: 35=6(5)+b. 35-30=b, b=5. So your final equation is y=6x+5.
Answer: The 4 answers are x=18, x=3, x=48, x=81 1/2.
Step-by-step explanation: Isolate the variable by dividing by each side by factors that don't contain the variable.
