Answer:-3(
)
Step-by-step explanation:
firstly we should find the common factor between 
, 6x and -9, the common between them is -3
-3()
and () cannot factorize
-
I can't graph the function but I can tell you that the equation is y= 20 + 2x
Answer:
$10.348
Step-by-step explanation:
(3.98)(2.6)= 10.348
You have to simplify the 1/5 first.
Then simplify the square root of 1 to equal 1
Then rationalize the denominator
Then simplify
First, part A is asking you for the association or correlation of the scatter plot based on the best fit line, or how strongly the scatter plot correlates to the best fit line. You have to find the correlation coefficient by using your graphing calculator for this (let me know if you need help with this). Then, if your correlation coefficient is positive and from 0.8 to 1, then there is a strong and positive correlation. If the correlation coefficient is positive and is from 0.4 to 0.7 (these are all approximate values), then the association is moderate and positive. The remaining range is for a weak and positive correlation. Everything is the same for a negative correlation coefficient, except for how the sign of the ranges and the correlation coefficient is negative.
I'm typing up how to do Part B now. :D
