Answer:
.
Step-by-step explanation:
We need to write an equation for the amount of chemical B as a function of the amount of chemical A.


...(1)
where, k is constant of proportionality.
It is given that fifteen grams of chemical A is used to produce 3 grams of chemical B. It means a=15 and b=3.
Substitute a=15 and b=3 in (1).


Substitute
in (1).

Therefore, the required function is
.
Answer:
x^2-6x+5
Step-by-step explanation:
To have roots at x=5 and x=1 you need to write is as follows
(x-5)(x-1)
you then need to multiply these two and get
x^2-6x+5
Answer:
6x - 3
Step-by-step explanation:
Step 1: Write out expression
2 - 3x - 5 + 9x
Step 2: Combine like terms (x)
2 - 5 + 6x
Step 3: Combine like terms (constants)
-3 + 6x
Step 4: Rewrite
6x - 3
Answer:
i think it's 11x-1
Step-by-step explanation:
2(1-3x)-(5x+1)
2-6x-5x-1
2-11x-1
11x-1
Answer:
its 2 :)
