We know that
the solution of the equations system is the intersection both graphs
first point of intersection is in the interval [-2,-1]
second point of intersection is in the interval [2,3]
<span>the only option that meets these two conditions is the option D
</span>-1.9 and 2.6
I’ll explain part A and you can apply it to the other parts. The functions f(x), g(x), and m(x) are all equivalent to the given polynomials. So when it asks for f(x) + [g(x) - m(x)] you plug them in. The answer to Part A is 3x^2 +5x - z + [5x^2-3x+z - 2x^2 - 2x]. Combine the like terms (3x^2+5x^2-2x^2 = 6x^2 (because 3+5-2=6)) and so on until you’ve simplified it as much as possible!
Answer:
k=5
Step-by-step explanation:
remove parenthese, combine like terms, move terms, combine like terms, divide both sides
Answer:
You can opt to study the entire population when the population is well defined(Complete sampling frame) and small.
It can eliminate any potential bias occurring through sampling technique, but other than that it is really not justified to consume more resources and time.
