Answer:
The final answer in the most simplest form is 3/32
Step-by-step explanation:
3/8(3/4+5/6)-1/2
3/8( 38/24)-1/2
114/192-1/2=36/184
Divide by 12 for the 36 and 184
the final answer should be 3/32
The square root of 202 is approximately 14.21
multiply the tops and bottoms, so:
1 * -5 * 3 = -15 for top
and
5 * 7 * 4 = 140 for bottom
then reduce by dividing by 5, and you get:
-3/28
I believe you are trying to find the coordinates if you reflect the given point (2, 5) over the line y = -x. Is this what you are looking for?
If so, the reflected point would be: (-5, -2). That is probably the missing choice D in the answers that you gave.
If you are looking for something else, please let me know, so I can help.
The translation of the question given is
A line that passes through the points A (2,1) and B (6,3) and another line passes through A and through the point (0, y). What is y worth, if both lines are perpendicular?
Answer:
y = 5
Step-by-step explanation:
Line 1 that passes through A (2,1) and B (6,3)
Slope (m1) = 3-1/6-2 = 2/4 = 1/2
y - 1 = ( x -2)
2y - 2 = x- 2
y =
Line 2 passes through A (2,1) and (0,y)
slope (m2) =
Line 1 and Line 2 are perpendicular
m1*m2 = -1
* = -1
y-1 = 4
y = 5
slope = -2
Equation of Line 2
Y-1 = -2(x-2)
y -1 = -2x +4
2x +y = 5
