Use complete sentences to describe why Set A = {x|x is an even whole number between 0 and 2} = ∅.
Vanyuwa [196]
A={x|x is an even while number between 0 and 2} = ∅ since there is no number between 0 and 2 that is an even whole number. So there is no number to be substituted for x, resulting in an empty set.

Hope that helps!

Write the equation of a line that passes through (-3/2, -5) and perpendicular to a line that contains (-1, -2) and (-2, -8).
liraira [26]

Answer:

find gradient/slope

-8-(-5) / -2-(-1) = -3/-1

= 3

y=3x+c

perpendicular line formula

m1(m2)= -1

(sub in the gradient before)

3(m2)= -1

m2= -1/3 ( perpendicular line gradient)

y=-1/3x+c

(sub in the coordinate)

-5=-1/3(-3/2)+c

-5=1/2+c

-11/2=c (y intercept)

answer: y= -1/3x - 11/2
