Answer:
8 and 8
Step-by-step explanation:
The magnitude of a number is the positive distance it is from the origin. The number 8 is 8 units from the origin (in the + direction). The number -8 is also 8 units from the origin (in the - direction).
Both 8 and -8 have a magnitude of 8 units.
ANSWER :
a. {2, 6, 9}
b. {6}
EXPLANATION :
From the problem, we have the sets :
A' denotes the elements that are NOT present in A but present in U.
B' denotes the elements that are NOT present in B but present in U.
That will be :
a. A' ∪ B'
The symbol ∪ denotes the union of two sets.
That will be :
b. A' ∩ B
The symbol ∩ denotes the intersection or common elements of the two sets
That will be :
The correct answer is A the greater value sign is closed and the other is open on the graph the answer is A
Step-by-step explanation:
Let us consider the length of a line segment to be 'x'
Let the other line segment be 'y'
One line segment is 12 less than twice the length of other segment.
X = 2y - 12
The sum of both the lengths = 69cm
X + Y = 69
X = 69 - Y
Substitute the X value in the first equation
X = 2y - 12
69 - Y = 2Y - 12
- Y - 2Y = -12 -69
- 3Y = - 81
3Y = 81
Y = 81/3
Y = 27 CM
Length of One of the line segment is 27cm
The length of the other line segment 'x'
is
X= 2y - 12
X = 2(27) - 12
X = 54 - 12
X = 42cm
The length of the line segments are 42cm and 27cm.
Answer:
Step-by-step explanation:
<em>Step 1: Define the problem</em>
Given:
Lorrie biked miles in time hours.
Lorrie traveled at speed which is greater than (mile/hour).
Task:
Lorrie wants to determine the distance she may have traveled.
Key point:
The relation among the distance biked , time , and the speed is represented:
x
<em>Step 2: Substitute given data into the main relation</em>
with: and
=> x
=> > x
Simplify:
<em>Step 3: Verify Lorrie's inequality</em>
Lorrie uses the inequality to conclude that she traveled a distance at most miles, or .
Considering the correct answer is at step 2, in which, .
=> Lorrie's conclusion is incorrect.
Hope this helps!
