Answer:
x = 5 ± 
Step-by-step explanation:
Given
x² - 10x + 25 = 17 ← left side is a perfect square, thus
(x - 5)² = 17 ( take the square root of both sides )
x - 5 = ± ( add 5 to both sides )
x = 5 ±
Thus
x = 5 -
x = 5 +
Answer:
domain: all real numbers
range: y<-2
Step-by-step explanation:
I think its correct but already know the answer sooo yea
Answer:
0.8
Step-by-step explanation:
4/5 is 0.8 as a divison expression.
Use inverse proportion ratio: xy=k
(124)(7)=k
k=868 (this is our constant)
now substitute the constant into the inverse proportion ratio knowing the number of workers
28x=868
solve for x by dividing both sides by 28 to find the time it takes to build the house
x=31 days
so it will take 31 days for 28 workers to build the house
Answer: Simplified it would be 103,743
Hope this helps! :)
