Step-by-step explanation:
<u>Equations with absolute value
</u>
The absolute value of a number x denoted as |x| is a number with the same magnitude with a positive sign. When we know the result of an absolute value, we cannot know if the original number is positive or negative.
If |x| = a, a>=0, then x=a or x=-a
The equation to solve is |x – 5| = 1. If we apply the above criteria, then
x-5=1 or x-5=-1
Which gives us two possible solutions for x
x=6
x=4
The correct answer is
Two points, one at 4 and one at 6.
Answer:
Step-by-step explanation:
We have the expression:
To solve this equation we must factor:
1.- Take common factor x.
2.- Evaluate the expressions to know when they are equal to 0.

Answer:
706.5
(there is no hundredths place)
Step-by-step explanation:
r=15
a= pi × r²
3.14×15²
15²=225
3.14×225=706.5
