Hello, again!! :p
I'm not sure about the whole equation because I was taught to solve it in a different way and I got the answer =3 ± i√ 6 ,not a -3.
Sorry, I'm not sure if that was much help!
It is in need of ignoring the absolute value sign when solving differential equations because they may interfere with the solution or in a way that the values that are being calculated may have a different answer in which is not the right answer to the given equation.
To find the gradient of the perpendicular line, we know that we must do the negative inverse of the current line's gradient
-6x from the old line will now be 1/6x
we are given points on that line and we therefore use the points and the new gradient to find the equation of the line using this formula
y-y1=m(x-x1) where m is the gradient
input the values that we have
y-5=1/6(x--4)
rearrange
y-5=1/6(x+4)
y-5=1/6x+4/6
6y-30=x+4
6y=x+34
y=1/6x+34/6
y=1/6x+17/3
Answer:B
Step-by-step explanation:
Andy money doubled. i.e. $3000
The second day made profit. $3000 + $165
Later he lost $238
The expression is:
2*1500 + $165 -$238
Good luck.
