Answer:
x = 2
Step-by-step explanation:
x/(x+1) = (x+6) / (x+10)
the 10 comes from 9+1
Then cross multiply and solve for x
the terms cancel out just leaving behind a nice linear function.
Start with vertex form and eliminate parentheses.
.. y = a(x -h)^2 +k . . . . . . where (h, k) is the vertex
The value of "a" will be greater than zero if the parabola opens upward, as shown.
Using this form, your equation is
.. y = 1*(x +6)^2 -9
.. y = x^2 +12x +36 -9
.. y = x^2 +12x +27 . . . . . . the desired form
Answer:
0.02
Step-by-step explanation:
If n is 50, 1/n is equivalent to 1/50. 1/50 as a decimal is 0.02.
