Answer:
Since, the given solution is (2, 14). Therefore, 7x−y=0. Similarly, another equation can be−x+y=−2+14=12. Similarly, another equation can be−2x−y=−2(2)−14=18.
Answer:
(x, y) = (-6, -4)
Step-by-step explanation:
The solution can be found quickly using a graphing calculator. It is the point of intersection of the two lines.
_____
If you like, you can solve the system algebraically. The second equation can be rewritten to give ...
y = x +2
Substituting this into the first equation gives ...
5/3x -2(x +2) = -2
-1/3x -4 = -2
Adding 4 and multiplying by -3 gives ...
x = -3(-2+4) = -6
Then our equation for y tells us ...
y = -6 +2 = -4
The solution is (x, y) = (-6, -4).

<h3>What is monomial factorization ?</h3>
A monomial is an expression that is the product of constant and non-negative integer powers of x, like
..
A monomial is expressed as a product of two or more other monomials when it is factored.
Here,
a = 125

To find: a - b
a - b = 125 - 
a - b = 
We know that,

Finding the factored form of a - b using this method:


So, factored form of a - b is

The interval around the mean that contains 95% of the airfare is (250.2,524.2).
Normal Distribution is bell shaped and symmetrical in nature.
We use standard normal to find probabilities of normal distribution
Normal distributions have key characteristics that are easy to spot in graphs: The mean, median and mode are exactly the same. The distribution is symmetric about the mean—half the values fall below the mean and half above the mean. Diagram below shows standard normal figure.
In a normal distribution, 95% of the values fall between mean±2*sd
Give: mean=387.20
sd=68.50
So the interval around the mean that contains 95% of the airfare is (250.2,524.2).

Answer:
114
Step-by-step explanation:
Supplementary means that all the angles in your givens add up to 180 degrees.
Givens
<A + <B = 180
<A = 2x + 6
<B = x + 3
Solution
<A + <B = 180 Substitute for <A and <B
2x + 6 + x + 3 = 180 Combine like terms on the left.
3x + 9 = 180 Subtract 9 from both sides
3x = 180 - 9
3x = 171 Divide by 3
x = 171/3
x = 57
That's not your answer.
<A = 2x + 6
<A = 2*57
<A = 114
