Determine the value of a so that the line whose equation is ax+y-4=0 is perpendicular to the line containing the points (2,-5) a
soldi70 [24.7K]
First, write the equation of the line containing the points <span>(2,-5) and (-3,2).

We can use 2 point form, or point-slope form.

Let's use </span>point-slope form.

the slope m is \frac{-5-2}{2-(-3)}= \frac{-7}{5}, then use any of the points to write the equation. (ex, pick (2, -5))

y-(-5)=(-7/5)(x-2)

y+5=(-7/5)x+14/5

y= (-7/5)x+14/5 - 5 =(-7/5)x+14/5 - 25/5 =(-7/5)x-11/5


Thus, the lines are 

i) y=-ax+4      and  ii) y=(-7/5)x-11/5

the slopes are the coefficients of x: -a and (-7/5),

the product of the slopes of 2 perpendicular lines is -1, 

so 

(-a)(-7/5)=-1

7/5a=-1

a=-1/(7/5)=-5/7


Answer: -5/7

77.1% chance that all 3 orders are correct.
For three independent events to find the probability of each one occurring we multiply the probabilities together. .917*.917*.917 = .77109 or 77.1 percent chance of all three outcomes being favorable.
