The L.C.M of 2and 4 is what?
2 answers:
Hello.
First, let's clarify what the LCM stands for.
L stands for Least
C stands for Common
M stands for Multiple
So we need to find the Least Common Multiple of 2 and 4.
Let's list the first 5 multiples of 2:
2, 4, 6, 8, 10
Now, the first 5 multiples of 4:
4, 8, 12, 16, 20
As we can see, 4 is the LCM.
I hope it helps.
Have an outstanding day. :)

Let's start by tidying up that equation and put it into slope-intercept form (y = mx + b); from there, we can plug in coordinates.
Let's use the distributive property on the right side:
Now add 4 to both sides
Which simplifies to:
Since that's the equation of our line, now we can plug in coordinates and see what it churns out.
We know that the x-coordinate of P = 4 so let's substitute 4 in for x and calculate the y-coordinate:
So the y-coordinate for point P = 10

Answer:
C 8.0
Step-by-step explanation:
Assuming the linear model y=mx+b where m is the slope and b the intercept.
For this case the slope with the following formula:
Where:
After the calculations we see that m=3 and b=2 from the info given by the linear model.
For this case we have the equation obtained by least squares given by:
Where 2 represent the intercept and 3 the slope. We are interested on the best predicted value of y when x=2.
If we see our linear model we have the equation in terms of y and x. So we can replace directly the value of x=2 into the equation and see what we got:
