Answer: The answers are given below.
Step-by-step explanation: We are given to factorise some quadratic expressions.
We will be using the following factorisation formula:
The factorisation is as follows:
We have
Thus, option (B) is correct.
Thus, option (B) is correct.
Thus, option (B) is correct
Thus, option (D) is correct.
Thus, option (C) is the correct option.
Thus, option (B) is the correct option.
Thus, option (D) is correct.
Solution:
we are given that
The state of New Jersey has a population of about 8.9 million and its area is about 8700 mi².
we have been asked to find the population density of New Jersey?
As we know the population density is defined as the population per square unit of area.
Population=8.9 million=8900000
Area=8700 mi².
Hence population density can be given as
The population density of New Jersey 1023.
<u>Using y = mx + b</u>
8y = 4x - 16 ⇒ y = - 2
-x = -2y - 4 ⇒ 2y - x = - 4 ⇒ 2y = x - 4 ⇒ y = - 2
Since the equations have the same slope () and y-intercepts (-2), then they are the same line. Thus, they intersect at every point so have infinite solutions.
