X is probably 89 might be wrong
60. set up ratios 45/75 = x/100
Answer:
Option B will be the correct one.
Step-by-step explanation:
The factor of a polynomial, y = f(x) is obtained by making f(c) = 0 and then solving the equation f(c) = 0 for c and then from the obtained value of c we say (x - c) is a factor of the polynomial y = f(x).
Now, on the reverse, the term (x - a) will be a factor of a polynomial, y = f(x), if and only if f(a) = 0.
Therefore, option B will be the correct one. (Answer)
Answer:
i found this picture on google i just looked up. it should have your answer here. i play flute, so i dont understand it all that much :/
hope this helps
second pic is a flute chart ;P
Step-by-step explanation:
So xy=-60 and x+y=-28
x+y=-28 also means x=-28-y
subsitute x=-28-y for x in xy=-60
(-28-y)y=-60
-28y-y^2=-60
add negative y^2 to both sides
-28y=-60+y^2
add 28y to both sides
0=y^2+28y-60
factor
0=(x-2)(x+30)
we set them to zero
x-2=0
x=2
x+30=0
x=-30
the numbers could be -30 and 2
