Answer:
(a)
if
then
and if x<0 then 
(b)
That is straightforward from what you showed on theorem 3.25
(c)
Following the same ideas from (a) x>a or -x > a.
Step-by-step explanation:
Remember how we define the absolute value of a number.
(a)
In general

Therefore if
you have two cases, if
then
and if x<0 then 
(b)
That is straightforward from what you showed on theorem 3.25
(c)
Following the same ideas from (a) x>a or -x > a.
Answer:
One rational solution
Step-by-step explanation:
proof
5x2 - 2x - 3=0, the sum of coefficients is 5-2-3=0, so the equation has exactly two solutions, x=1, and x = -3/5 this last is the one rational solution
Answer: H- hot dogs
J- juice box
6h+4j=16.70
3h+4j=10.85
Elimination:
-6h-4j=-16.70
3h+4j=10.85
-3h=-5.85
H= 1.95
3(1.95)+4j=10.85
5.85+4j=10.85
4j=5
J=1.25
