We have that
F(x)=x²<span>-10x+44
</span><span>Group
terms that contain the same variable
</span>f(x)=(x²-10x)+44
<span>Complete
the square Remember to balance the equation
</span>f(x)=(x²-10x+25-25)+44
Rewrite as perfect squares
f(x)=(x-5)²-25+44
f(x)=(x-5)²+19
this is the equation of a vertical parabola with vertex (5,19)
see the attached figure
2 is a,c,d
3, none of the options are correct.
4 could be 3v + 5m
5 can be 11(2x+y)
The second one would be y=-2x+5, and it would only have one solution.
solution is (2.5, 0)
The answer is m=3/4 hope this helps
