The top right one, it goes over 1, up 1
4(3+5) --> this means that 12/4=3 and 20/4=5 and 4 is the GCF
Answer: The regression equation could have a positive or a negative slope
Explanation:
The coefficient of determination is marked as r^2. This is always positive because squaring a negative leads to a positive. Knowing something like r^2 = 0.7 does not tell us whether r itself is positive or negative, so we don't know if the regression line slope is positive or negative. We would need more info.
Answer:
Step-by-step explanation:
yes
if you solve the equation,
5x+15=7x-11
