let me know if you know for sure what the answer is

➷ Use this equation:

slope = difference in y values / difference in x values

Substitute the values in:

slope = (10 - 10) / (2 - 4)

slope = 0 / -2

slope = 0

The correct option is C. 0

51

step-by-step explanation:

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons

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
