Answer:
B, coefficient vertically stretches or compress not horizontally, plus it is negative so x axis dlip
You have to find two definite points on the graph, i'll use (1,4) and (2,6) as an example
The slope formula is (y2-y1)/(x2-x1)
This means you have to subtract the first y value from the second divide it by the first x value subtracted from the second
In my example you have to do (6-4)/(2-1) to get 2/1, or 2

Answer is A
X-3/x^2-4 has two excluded values 2, -2
Answer:
The answer is
<h2>
</h2>
Step-by-step explanation:
To find an equation of a line when given the slope and a point we use the formula
where
m is the slope
( x1 , y1) is the point
From the question the point is (5, -6) and slope - 3/5
The equation of the line is
We have the final answer as
Hope this helps you
Answer:
84%
Step-by-step explanation:
What we must do is calculate the z value for each value and thus find what percentage each represents and the subtraction would be the percentage between those two values.
We have that z is equal to:
z = (x - m) / (sd)
x is the value to evaluate, m the mean, sd the standard deviation
So for 190000 we have:
z = (190000 - 200000) / (10000)
z = -1
and this value represents 0.1587
for 230000 we have:
z = (230000 - 200000) / (10000)
z = 3
and this value represents 0.9987
we subtract:
0.9987 - 0.1587 = 0.84
Which means that it represents 84% of the houses
