Answer:3/8
Step-by-step explanation:
-2|x-4|+7 = -3
-2|x-4| = -10
|x-4| = 5
Two forms:
x-4 = 5 : x = 9
or
x-4 = -5 : x = -1
Answer:
R is a partial order
Step-by-step explanation:
The relation is reflexive
That is to say, aRa
The relation is antisymmetric, if aRb and bRa, then a=b
The relation is transitive, if aRb and bRc, then aRc
Finding the zeros is just factoring the equation. It is also where the parabola crosses the x- axis.
First you need to find two numbers that mutliply to give you -21 and add to give you 4 then you put it into this form:
(x +7)(x-3) set each part equal to zero
x+7=0 and x-3=0 you get:
x=-7 and x=3 your zeros
