the cost of 4 bags of popcorn is $9.80 ( 2.45 x 4 )
the total weight of the popcorn would be 40 ounces ( 4 x 10 )
sub
<span>
</span>
since -x^2+x+19=y
<span>
</span>
x=-x^2+x+19+80
<span>
</span>
x=-x^2+x+99
<span>
</span>
0=-x^2+99
<span>
</span>
x^2=99
x=3√11
x=y+80
3√11=y+80
minus 80 both sides
-80+3√11=y
x=3√11
y=-80+3√11
solution
(x,y)
(3√11,-80+3√11)
The correct answer is that the angles created are equal.
The steps given are used to create an angle bisector of the angle. That means it divides the angle into 2 congruent angles.
This is the picture of the line
good luck
