5. which of the following represent a line perpendicular to y = 2x + 7?
1. y = 2x - 7
* ii. y =-*-
iii. y + 5 = -(x + 3)
a. i only
b. ii only
c. ii and iii d. none of the abo

step-by-step explanation:

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

factor trees are nice.
