Firstly, let's factorise each equation individually - to do this, find 2 numbers that when summed add to the value of the second term, and when multiplied give the value of the third term.
7 and 12 give us 4 and 3 (4+3=7, 4*3=12) -- 8 and 15 give us 5 and 3 (5+3=8, 5*3=15)
Now we can rewrite these equations as (y+4)(y+3) and (y+5)(y+3) respectively.
Putting this in a fraction: (y+4)(y+3)/(y+5)(y+3) -- We can clearly see that there is a y+3 on both sides of the fraction, and given there are no terms outside of the brackets being multiplied, we can directly cancel.
This gives us our final answer:
(y+4)/(y+5)
Answer:
ZERO
Step-by-step explanation
Write the given function as
F(x) = ax + b
i.e Y = ax + b
now differentiate Y with respect to X
dY/dX = d (ax + b)/ dx
dY/dX = a
now again differentiate this function with respect to x
so, d^2Y/dX^2 = d^2 (a)/dX^2
= 0 (ZERO)
note: differentiation of constant function is zero
The question mark is 100. It is a variable if you don't know
It's 369.6
(840X44)/100 = 369.6
