Well, so the x+5y= 0 you can make this into x=-5y and then plug this in into ( y=9-2x) the -2x , which these would become y=9-2(-5y) simplify and equals to y=9+10y. Then you simplify much smaller y=-9. Now that you have the y number you just plug this in into x=-5y, which these becomes x=-5(-9) and the answer is x=45. At the end you just need to find the x and y, so the answer is x=45 and y=-9 . Hopefully this would make this much easier to you.
Answer:
3x(2x - 3)(2x + 3)(5x - 1).
Step-by-step explanation:
60x4 − 12x3 − 135x2 + 27x
= 3x(20x^3 - 4x^2 - 45x + 9) We can factor what's in the parentheses by grouping:
= 3x(4x^2( 5x - 1) - 9(5x - 1))
= 3x (4x^2 - 9)(5x - 1) Now we factors 4x^2 - 9:
= 3x(2x - 3)(2x + 3)(5x - 1).

Answer:
The father is 50 and his son is 15.
Step-by-step explanation:
Double the tens digit of the father's age = 10
Plus 5 = 15 (the age of the son)
50 + 15 = 65 (the sum of their ages)
The reverse of the digits of the son's age is 51.
Subtract 1 = 50 (the age of the father)
