Answer:
y = -2·x^2 - 5·x - 18
y = -2·(x^2 + 10·x + 36)
y = -2·(x^2 + 10·x + 36)
y = -2·(x - (-5 - √11·i))·(x - (-5 + √11·i))
Maybe there is a typo in the original question, because there is no factorisation in the real numbers.
Because the question is " find the minimum value of y" the coefficient before x^2 must be a positive number. so it could be
y = 2·x^2 - 5·x - 18

Answer:
x+9/x+1
Step-by-step explanation:
Since the denominator is the same, just add the numerator while keeping the denominator the same.
Answer:
ok, anddddd???
Step-by-step explanation:
So basically the question just wants you to add fractions so we set up the problem like this
1/2+1/5+1/8=weight of herbs=x (x signifies an unknown number)
so
we have to get the bottom numbers the same before we can add them so we
have to find the smallest number that they all can multiply into
so
2=2
5=5
8=2*2*2
so the smallest number that that will go into all three of the numbers is
2*2*2*5 =40
so the bottom number will be 40
so 1/2 is equal to 20/40
1/5=8/40
1/8=5/40
so 20/40+8/40+5/40=33/40
answer is 33/40 grams
so
