Answer:
y = - 8
Step-by-step explanation:
The given line passes through (-4, 4) and (4, -2)
The slope of this line will be given by: Change in y ÷ change in x
Slope = = =
The slope of the given line times the slope of the perpendicular line = -1
Let's say the slope of the perpendicular line is p
Then, × p = -1
p = -1 ÷ =
The perpendicular line passes through point (6, 0)
Taking another point (x, y) on the perpendicular line;
=
Cross multiplying this gives the equation of the perpendicular line to be:
y = - 8
Distribute the 32 to the 4x and -2, so you have 128x-64-3x=5-(x+2), then you distribute the “-“ sign to x and 2 so on the right you have 5-x-2. All together you have 128x-64-3x=5-x-2. Combine like terms on both sides so you have 125x-64=-x+3. Add 64 to both sides so you got 125x=-x+67. Also add x on both sides, so your final equation is 126x=67. This doesn’t come out to an even number but it’s ok, your answer in decimal is about 0.532 rounded to the thousandths and if you want a fraction it’s simply 67/126. I’m sorry if this answer isn’t correct I did this in my head.
Yes if you tell us wha5 your question is.
Step-by-step explanation:
a)
t(x) = x*(1 + 0.06)
b)
d(x) = x*(1 + 0.06)*(1 - 0.1)
c)
It doesn't matter because a * b = b * a
So x*(1 + 0.06)*(1 - 0.1) will be the same as xx*(1 + 0.06)*(1 - 0.1)*(1 + 0.06).
