<span>Find the equation of the line parallel to the line y = 4x – 2 that passes through the point (–1, 5).
</span>y = 4x – 2 has slope = 4
<span>parallel lines have same slope so slope = 4
</span><span>passes through the point (–1, 5).
</span><span>y = mx+b
5 = 4(-1) + b
b =9
equation
y = 4x + 9
answer
The slope of y = 4x – 2 is 4
The slope of a line parallel to y = 4x – 2 is 4
The equation of the line parallel to y = 4x – 2 that passes through the point (–1, 5) is y = 4x + 9</span>
<span>Ans : a)
What is the standard deviation of this sampling distribution?
Ď /âšn
= 60/âš840
=2.0702
b)
1 standard deviation of the mean
= (1) 2.07
= 2.07
c)
272+/- 1(2.07)
(269.93, 274.07)</span>
Answer:
x^2-7
Step-by-step explanation:
42 acres to 72 acres, there is an increase of 30 acres
percentage wise
72-42=30
30/72=.4166...
therefore there is also a 41.6% increase
Answer:
So if I did my math right it should be (4,3.5)
Step-by-step explanation:
The formula for finding a midpoint of a segment is (x1+x2/2 , y1+y2/2)
So first you grab both x's out of (-1,2) and (9,5).
So -1 and 9.
Then you add them and divide them by 2 to get 4
Then you grab the y's out of (-1,2) and (9,5)
So 2 and 5.
Add 2 and 5 together and divide them by 2.
That's when you should get 3.5
So the midpoint should be (4,3.5)
