Answer:
Answer:
Option C.
Step-by-step explanation:
The vertex form of a parabola is
where, a is constant, (h,k) is vertex.
If a<0, then it is a downward parabola and if a>0, then it is an upward parabola.
A downward parabola never lies entirely above the x-axis.
First equation is
It is a downward parabola and vertex is (-7,7).
Second equation is
It is an upward parabola and vertex is (7,-7).
Third equation is
It is an upward parabola and vertex is (7,7).
Fourth equation is
It is a linear equation with y-intercept -7.
Only equation 3 is an upward parabola whose vertex lies above the x-axis.
You could either divide the 6 on each side and have 4=-3+x, so x=7, or you could distribute the 6 into the expression, so 24=-18+6x. Then 42=6x, and x=7.
M is located in Quadrant II, the line BD has a midpoint located in Quadrant II, AD has a midpoint at the origin.
