Answer:
1) m = negative StartFraction 10 over 4 EndFraction
2) m = negative five-halves
3) m =
Step-by-step explanation:
<u>The given equation is:</u>
=>
Subtracting 3/4 to both sides
=> m =
=> m =
=> m =

Answer:
The answer is 4/9 if the problem is:
.
Step-by-step explanation:
I think this says:
.
Please correct me if I'm wrong about the problem.
Here are some useful limits we might use:
So for our limit... I'm going to multiply top and bottom by the conjugate of the bottom; that is I'm going to multiply top and bottom by :
When you multiply conjugates you only have to do first and last of FOIL:
By the Pythagorean Identities, the denominator is equal to :
I'm going to divide top and bottom by in hopes to use the useful limits I mentioned:
Let's tweak our useful limits I mentioned so it is more clear what I'm going to do in the following steps:
The bottom goes to 1. The limit will go to whatever the top equals if the top limit exists.
So let's look at the top in hopes it goes to a number:
We are going to multiple the first factor by the conjugate of the top; that is we are multiply top and bottom by :
Recall the thing I said about multiplying conjugates:
We are going to apply the Pythagorean Identities here:
Ok this looks good, we are going to apply the useful limits I mentioned along with substitution to find the remaining limits:
The limit is 4/9.
