The answer is a)
<span>0 imaginary; 3 real
proof
f(3)= = 27-20.9+123.3-216= 216-216=0
so f(x)=(x-3)(ax²+bx+c)=0
after doing euclidean division </span>
<span>ax²+bx+c= (x-8)(x-9)=x²-17x+72
and </span><span><span>x²-17x+72</span> = (x-8)(x-9)
so f(x)=(x-3)</span><span><span>(x-8)(x-9)</span>
f(8)= 8^3-20*64+123*8-216=216-216=0
f(9)=9^3-20*81+123*9-216=0

Assuming that the given expression is
You calculate dy / dx = y' as:
1
-------. y' = e^(x/y) * (-x/y^2)
x + y
=> y' = e^(x/y) * (-x/y^2) * (x + y).
Answer dy / dx = - e^(x/y) (x/y^2) (x+y)
Answer:
My guess is 2b^5
Step-by-step explanation:
This question is kinda tricky. LMK if its correct
Hey You!
6 × 30 = 90
280 - 90 = 190
190 / 2.50 = 76
We can check using multiplication.
2.50 × 76 = 190

Answer:
x = 5.25
y = 7.5
Step-by-step explanation:
Since line 1.5 is parallel to line x which is parallel to line y
then 2/(2+5) = 1.5/x
2x = 7(1.5)
2x = 10.5
x = 5.25
Similarly, 2/(2 + 5 + 3) = 1.5/y
2y = 10(1.5)
2y = 15
y = 7.5
