Make a substitution:
Then the system becomes
Simplifying the equations gives
which is to say,
Substituting this into the new system gives
Then
(meaning two solutions are (7, 13) and (-7, -13))
I think it would be 5/11
If I'm wrong plz don't report me
Have A Good Day
We are given: Degrees Celsius and degrees Fahrenheit are related by formula
To find : Solve formula for F in terms of C.
Solution: We have ,
First we need to get rid 9 from right denominator.
In order to get rid 9 from right denominator, we need to multiply equation both sides by 9.
9C = 5 (F-32).
Distributing 5 on right side over (F-32), we get 5*F - 5*32 = 5F - 160.
9C = 5F - 160.
Adding 160 on both sides,
9C+160 = 5F - 160+160.
9C+160 =5F
Dividing both sides by 5, we get
(9C+160)/5 =5F/5.
Splitting fraction 1/5, we get
.
Solution: Alyssa is incorrect.
In fact .
If we cross-multiply the above equation, we have:
Therefore, they are equal.
Also, if we reduce the given fractions, we have:
And
Since both the fractions reduced to , therefore fractions are equivalent.
Answer:
The slope would be 7
it could also be represented as m = 7
