g(9) = 9^2 - 2*9 = multiply the numbers:2*9=18 so g(9)=9^2-18 9^2=81 so g(9) =81-18 subtract the numbers: 81-18=63 so g(9) = 63 divide both sides by 9 g(9)/9 = 63/9 so g = 7
A positive trend increases y and x. The point wouldn't form a straight line because it is a scatter plot and it would have outliers. For further help look up "scatter plot with positive trend" and go to images. It makes more sense with a picture.
First, take a look at what's inside the brackets. You would start by distributing the negative to the m and the 80. 5[5m-(m+80)]>-8(m-6) 5[5m-m-80]>-8(m-6) Then distribute the 5 to what's inside the brackets. 25m-5m-400>-8(m-6) Then distribute the -8 to
