Step-by-step explanation:
Bir abzas qurmaq üçün 5 addımdan keçək. Hər addım üçün bir izah və nümunə var. Nümunə bəndimiz kölə ruhları haqqında, Afrikalı Amerikalıların köləlik dövründə yaratdığı orijinal mahnılarla əlaqəli olacaq. Model paraqrafı fikrini sübut etmək üçün illüstrasiyadan (nümunələr verməklə) istifadə edir.
we have
we know that
so
two solutions
<u>first solution </u>
the first solution is the interval---------> (-1,∞)
<u>second solution</u>
the second solution is the interval---------> (-∞,-1)
therefore
the solution is all real numbers except the number 
the answer in the attached figure
Answer:
3 hours
Step-by-step explanation:
To solve this we can first find out how many minutes is 1/5th of an hour which is: 12 mins.
Now we know it will take 15 sets of 12 minutes to water the full lawn so we can multiply 15*12 to get our answer.
15*12 = 180
Now we divide 180 (minutes) by 60 (minutes) to find out how many hours that is:
180/60 = 3 hours
Hope this helped! If possible please leave a thanks so I can continue to help out others :),
comment if you have any questions.
4x²+4x-35=0
factor: (2x+7)(2x-5)=0
2x+7=0, or 2x-5=0
2x=-7 or 2x=5
x=-3.5 or x=2.5
I don't see any rounding necessary in this case.
when you factor ax²+bx+c, you take the two factors of a and the two factors of c, one factor of a times one factor of c, the other factor of a times the other factors, the sum of the two products make b.
in this case, the factors of 4 is 2 and 2, the factors of -35 is -5 and 7. I line them up in the following way:
2 -5
2 7
then I multiple them diagonally, the top left 2 multiplying the bottom right 7=14, and the other 2 multiplying -5=-10, 14 and -10 make a sum of 4.
if you don't get the desired sum, switch the factors up and down till you have the right combination. Note: Do not switch left and right.
I hope this makes sense to you.
Hope this helps! Because when you would fill in the variables 0=0 which which make the expression too that they’d equal the same.
