|x - 1| > 4 ⇔ x - 1 > 4 or x - 1 < -4  |add 1 to both sides
x > 5 or x < -3
Answer: c. {x| x < -3 or x > 5}.

Answer:
Answer in terms of a trigonometric function :
 
 
Answer in figures 

Step-by-step explanation:
Consider the sketch attached below to better understand the problem.
Let x be the distance between point B and the base of the water tower.


From equation 2,
 
 
substituting the value of x into equation 1, we get
 

cross multiplying,



The height of the tower is  in terms of the trig function "Tan"
 in terms of the trig function "Tan"
The equation can simply be evaluated to get the answer in figures since the angles are given in the question

Answer:
x=-2 y=3
Step-by-step explanation:
The substitution is basically given to you. Exchange x from the second equation with y-5
Once that is done and you combine the parentheses you get:
2y-10+y=-1
Add 10 on both sides of the equal sign
You get:
3y=9
Divide both sides by 3
You get:
y=3
To check your work you can substitute y in the second equation with 3 and solve it that way to get x=-2 (x equals negative two)
