Answer:
(4,-4)
Step-by-step explanation:
(x,y)
y=3/4x - 7
y=3/4*(4)-7
y=3-7
y=-4
(4,-4)
In order to complete the square, the leading coefficient has to be a positive 1, which it is. Now we will set the polynomial equal to 0 and move the 2 over by subtraction to isolate the x terms.

. The rule now is to take half the linear term, square it, and then add it in to both sides. Our linear term is 6. Half of 6 is 3, and 3 squared is 9, so we add 9 to both sides.

. Simplifying we have

. During this process, and the reason for it, was to create a perfect square binomial on the left which will give us the x coordinate (or the h) for our vertex. That perfect square binomial is

. Now we will move the 7 over by subtraction and set the polynomial back equal to y to get

. Our vertex, then, is (3, -7) and this is a min value since our parabola is positive and opens up like a cup that has a bottom instead of mountain that has a top. And there you go! Your answer is C
Answer:
{2,3}
Step-by-step explanation:
The domain is the set of all the values of x. The range is the set of all the values of y.
Find the ratio of the known sides 10 and 12
12/10 = 1.2
The larger kite is 1.2 times the size of the smaller kite.
Multiply 7 by 1.2:
x - 7 * 1.2
x = 8.4
