The equation of line xy is (y-3)= -2/3(x-4).what is the slope of a line perpendicular to xy?

a) -2

b) 3

c) -2/3

d) 2/3

will be the slope of the line perpendicular to xy.

Step-by-step explanation:

The equation of line xy is ( y-3 ) = (x-4)

y = ( x-4 ) + 3

y = x + + 3

y = x +

So the line has slope = and y-intercept = .

Let m is the slope of a line perpendicular to line xy.

We know that for perpendicular lines having slopes m₁ and m₂

m₁ × m₂ = -1

Therefore, for m₁ = m and m₂ =

mx () = -1

m = ()

will be the slope of the line perpendicular to xy.

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
