Is about inequalities, I know the rule of flipping the sign if you multiply or divide by a negative numbers but a few examples c
onfuse me. To make this inequality 5x+2y<14 into the slope-intercept form y=mx+b, please tell me if the sign has to be flipped.
I do it like this
5x+2y<14
y<-5/2x+14/2
y<-5/2x+7
I am not dividing by a negative number but 5 is negative, 2 is positive, should I flip the sign or not?
Given : A scatter plot is made with the data shown below: Number of Waiters at a Restaurant 5 6 7 8 9 10 11 12 13 Customer Service Rating 4 2 10 7 1 2 8 9 5
To find : What type of association will the scatter plot for these data represent between the number of waiters at a restaurant and its customer service rating.
Solution : We have given :
Number of Waiters at a Restaurant = 5 6 7 8 9 10 11 12 13
The result of this division is x + 1 plus a residue of - 8x^2 + 8x - 4.
It was expected an exact division, so likely some of the terms is not properly written. Now you know the procedure and can perform it with the right terms.
