Answer:
The mode of sunday is 15 is correct
The following steps of solving for the roots of 2x² - 4x -3 = 0 were retrieved from another source
Step 1 2x² - 4x = 3
Step 2 2(x² - 2x) = 3
Step 3 2(x² - 2x + 1) = 3 + 1
Step 4 2(x - 1)² = 4
From this, we can see that on Step 3, Tran made a mistake of adding 1 to 3. As we can see, 2(x² - 2x + 1) = 2x² - 4x + 2. That means, instead of adding 1, it should have been 2.
Therefore, the step that Tran first made an error is Step 3<span>.</span>
Answer:
-x
Step-by-step explanation:
First you cancel the x^3 and the -x^3 because together, they equal 0.
Then you are left with 3x - 4x.
That equals -x.
Answer:
The original population of State A was half of the original population of State B.
Step-by-step explanation:
<u>State A:</u>
The population f(x), in millions, of State A of a country after x years is represented by the function
Initially, at x = 0, the population was
<u>State B:</u>
The graph shows the population g(x), in millions, of State B of the country after x years. From the graph, at x = 0, the population in state B was (the graph intersects the y-axis at point (0,2)).
Hence, the original population of State A was half of the original population of State B.
