Solve this compound inequality 3x < -6 or 7x > 56

 and  

Step-by-step explanation:

Solving the first inequality:

Solving the second inequality:

So the first inequality tells us that x is any value less than -2, and

the second inequality tells us that x is any value greater than 8

So the answer is    and  

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

i believe that the answer is

b. y-1=-2(x-4)

hope this !
