It should be (2x-3)x(3x+2)
Y=mx+b, m=(y2-y1)/(x2-x1)
m=(7-4)/(6--3)=3/9=1/3
y=x/3 +b, now use either point to solve for b, I'll use (6,7)
7=6/3 +b
7=2+b
b=5 so our line is:
y=x/3 +5 or more neatly...
y=(x+15)/3
Males have chromosome pairs of (XY) and Females have chromosome pairs of (XX)
If 
, then 
. You replace all x's in the function with -3.

Finish by evaluating the absolute value and then adding that to the 5 that's behind the absolute value.
Can you finish it from there?
Answer:
e°=100°
Step-by-step explanation:
Sum of angles in a triangle= 180°
70°+30°+x°=180°
100°+x=180
Collect like terms
x°=180-100
x°=80°
e° is an exterior angle
exterior angle =180- interior angle
180°- x°
180°- 80°
=100°
e°=100°
