Point M represents the opposite of - and point N represents the opposite of
which number
line correctly shows points M and N?

the graph in the attached figure

Step-by-step explanation:

we know that

point m represent the of negative 1/2

so

m= +1/20=0.5

point n represent the opposite of positive 5/2

so

n= -5/2 = -2.5

using a graphing tool

see the attached figure

if i'm not wrong, i would say that the third angle has (72) because the three sides of all triangles have 180 degrees and if we subtract 180 - 62 - 40 = (72) / but i'm not sure about 40 yd.

(f+g)(x) = 3^x+10x+4x-2

      =3^x +14x-2

choice b
