Answer:
This equation has ONE unique solution, which is x = 1.
Step-by-step explanation:
Let's actually solve this equation, 0.9x+5.1x-7=2(2.5x-3).
Mult. all four terms by 10 to eliminate the fractions:
9x+51x-70=2(25x-30)
Perform the indicated multiplication:
9x+51x-70= 50x - 60
Combine like terms: 60x - 70 = 50x - 60 => 10x = 10, and x = 1
This equation has ONE unique solution, which is x = 1.
When conducting a survey, it is critical that you choose a sample to represent the population you's conducting the survey for or about. It is extremely critical that this sample is neutral and unbiased to ensure that the results are trustworthy and can represent the whole population. That's why you use a random sample.
Answer:
<span>When conducting a survey, it is important to use a random sample because random sample provides an unbiased representative sample for the survey.</span>
Answer: spread , gap, peak, cluster
Step-by-step explanation:
Just did it
Looks like a transformation of x^2 where it is stretched vertically.
When x = 1 , f(x) = 4 and when x = 2 f(x) = 16
Yes its f(x) = 4x^2
Area of a square: s^2
Because we know the length of one side, we can multiply it by itself to find the area.
(3x - 6)(3x - 6)
9x^2 - 18x - 18x + 36
Combine like terms.
9x^2 - 36x + 36
<h3>The correct answer is A, or the first answer. </h3>
