0.85 is equal to 6/7 because you divide six by seven....Hope this helped.
D. there is a perfect association between the variables
<h2 /><h2>45 - 20 = m</h2><h2 /><h2>OR m = 45 - 20</h2><h2 /><h2>Hope that helps!</h2>
Answer:
(x , y) ----> (-x , y)
Step-by-step explanation:
(x , y) ----> (-x , y)
Example for 1. :
(-4,2) ---> (4,2)
The slope of the parallel line is -6/7
the slope of the perpendicular line is 7/6
the slope of the line = -6/7
the gradient of two parallel lines are equal
the product of the gradient of two perpendicular lines is -1
: the gradient m1*m2 = -1
m2= -1(-6/7)
m2= 7/6
