What is the slope of a line that is perpendicular to the line 2y - 3x = 87

-2/3

Step-by-step explanation:

We need to put in slope intercept form..

Once we identify the slope of the line given, we can find the slope of the perpendicular line which is the opposite reciprocal of the slope for the given equation:

Let's do this:

2y-3x=86

add 3x on both sides to get 2y by itself

2y=3x+86

divide both sides by 2

y=3/2 x+43

So the slope is 3/2

The opposite reciprocal of 3/2 is -2/3 .

The answer is -2/3

option: d is correct

step-by-step explanation:

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
