Answer:
4, 8, 16.
Step-by-step explanation:
Let the three numbers in GP be
, where
. We are given that
and
, the latter of which gives
. So substituting this into the former equation gives
or

And this gives our answer directly.
Answer: The slope is 1/2
Step-by-step explanation:
Calculate the rise (change in y-component) divided by the run (change in x-component).
rise = 0 - (-5) = 5
run = 12 - 2 = 10
slope = 5/10 = 1/2
just use FOIL (First, Outer, Inner, Last).
( √2 - √3 ) X ( √2 - √3 )
First: √2 X √2 = 2
Outer: √2 X -√3 = -√6
Inner: -√3 X √2 = -√6
Last: -√3 X -√3 = 3
and then add them together.
2 - √6 - √6 + 3
5 - 2(√6)
The answer is 5 - 2(√6) .
Answer:
Step-by-step explanation:
(1,1) (2,-2)
Y2 = -2 , y1 = 1 , x2 = 2 , x1 = 1
Slope m = (y2 - y1)/(x2 - x1)
m = (-2 - 1)/(2 - 1)
m = -3/1
m = -3
And the equation of line
y - y1 = m(x - x1)
y - 1 = -3(x - 1)
y - 1 = -3x + 3
y = -3x + 3 + 1
y = -3x + 4
