Alright,
So LCM stands for "least common multiple"
While GCF is "greatest common factor"
Let's look at your number 1 (3&6)
3,6,9,12
6,12,18,24
Both times table has 6 in them making 6 the LCM
To find the GCF we need to know what can go into 3 equally. Since 3 is prime the greatest factor for 3 is....3. 6 goes into 3 two times so 3 is the GCF.
LCM:6
GCF:3
Lets do number 10 (40&4)
For LCM you see whats the smallest number that is in both times tables
4,8,12,16,20,24,28.......40
40,80, 160....
40 is the LCM because 40 is what's the smallest number between the two
GCF?
4 times 1 equals 4. Nothing bigger than 4 can make 4 (if your multiplying). That makes 4 automatically the GCF. :)
Answer:
15
Step-by-step explanation:
Just insert 3 wherever the z is at.
5 * (6 - 3)
5 * 3
= 15
Answer:
A) 
- Linear
B) 
- Linear
C) 
- Nonlinear
Step-by-step explanation:
To determine whether a function is linear or nonlinear.
The function of a straight line is given as :
where 
represents slope of line and 
represents the y-intercept.
Any function that can be represented as a function of straight line is called a linear function otherwise it is nonlinear.
We will check the equations given for linear or nonlinear.
A)
The function is in the form and hence it is a linear function with slope 
and y-intercept 
.
B)
The function is in the form and hence it is a linear function with slope 
and y-intercept 
.
C)
On solving for 
Dividing both sides by 
This function cannot be represented in the form , hence it is a nonlinear function.
