Answer:
The vertex is (-3, 7)
Step-by-step explanation:
As the equation is already in 'rectangular form), to work out the vertex, we can just compare this equation to that of the standard parabola y = x^2, and in particular, consider how it has been translated:
the (x+3) part moves the graph the the left 3 (i.e in the negative direction), while the +7 moves the graph up 7.
So as the vertex of the simple parabola y = x^2 is (0,0), the vertex of this graph is just (-3,7).
Note that the -2 at the front doesn't impact this vertex - this -2 just changes the 'scale' of the parabola (i.e makes it more narrow, and also turns it upside down as it's a negative number).
Answer is (4,3)
=============================
Add up the x coordinates to get 9+(-1) = 8. Divide this over two and we end up with 8/2 = 4
Repeat for the y coordinates: 9+(-3) = 6, which cuts in half to get 6/2 = 3
The midpoint is at (4,3)
-------
The midpoint formula is
where (x1,y1) and (x2,y2) are the endpoints.
Answer:
Paul made the most shots at 75%, Eric mad the second best with 70% and Marc made the least (65%)

Alright so what you are doing is getting the area of the whole triangle, and that formula is what you do so bxh is 5x12 and 5x12=60 then you need to divide 60 by 2 which is 30 so your answer will be
B 30m^2
To find the x-intercept set y=0 and solve for x.
3x-7y=21
3x-7(0)=21
3x=21
x=7
so, x-intercept is at (7,0)
to find the y-intercept set x=0 and solve for y.
3x-7y=21
3(0)-7y=21
-7y=21
y=-3
so, y-intercept is at (0,3)
