Answer:
for example.
Step-by-step explanation:
The three vertices of a parallelogram ABCD, taken in order are A(1,−2), B(3,6) and C(5,10). Find the coordinates of the fourth vertex D.
We have system:
y=2x+1
y=2x^2+1
To find which ordered pair is solution to this system we need to solve system for x and y.
Left sides are same so the right sides must be same too.
2x+1=2x^2+1
2x-2x^2+1-1=0
2x-2x^2=0
2x(1-x)=0
x1=0
x2=1
y1=2*0+1=1
y2=2*1+1=3
The solution are pairs (0,1) and (1,3).
Answer:
<h2>
C. y = 54°</h2>
Step-by-step explanation:
y + y + 72 = 180
2y = 180 - 72
y = 108/2
y = 54°
