Answer:
10 degrees Celsius
Step-by-step explanation:
Since the line goes through point (50, 10) and x represents Fahrenheit, y represents Celsius, then 50 F= 10 C
If 90 equals to (x+2) and (x-6), then (x+2)=(x-6), which is impossible because 2≠-6
Answer:
e=2
Step-by-step explanation:
multiply both sides by 2 to get the variable by itself.
e=6
So for this polynomial, we will be completing the square. Firstly, what two terms have a product of 20m^2 and a sum of -12m? That would be -10m and -2m. Replace -12m with -2m - 10m: 
Next, factor m^2 - 2m and -10m + 20 separately. Make sure that they have the same quantity inside of the parentheses: 
Now you can rewrite this expression as
. <u>(m - 10) and (m - 2) are your two factors.</u>
