Answer:
Standard form of a quadratic equation is;
ax^2+bx+c=0
According to the above equations, all of them are in standard form.
Step-by-step explanation:
The answer is (3, 0) for The second endpoint.
Let's start by calling the known endpoint L and the unknown K. We'll call the midpoint M. In order to find this, we must first note that to find a midpoint we need to take the average of the endpoints. To do this we add them together and then divide by 2. So, using that, we can write a formula and solve for each part of the k coordinates. We'll start with just x values.
(Kx + Lx)/2 = Mx
(Kx + 7)/2 = 5
Kx + 7 = 10
Kx = 3
And now we do the same thing for y values
(Ky + Ly)/2 = My
(Ky + -6)/2 = -3
Ky + -6 = -6
Ky = 0
This gives us the final point of (3, 0)
Answer: 5(k)
Step-by-step explanation: “k”times “t” equals 6t-9 so if “k” times “t” equals 21, 6t-9=21, add 9 to 21 which equals 30 so then you divide 30 by 6 to get 5. “t”=5 which means the solution is 5(k)

14.59
To solve, simply plug -7.1 into -Z. Since Z is negative in the equation, it will turn the Z that’s given to us into a negative. Since that Z is already negative, it will now become a positive since that’s what two negatives being multiplied make. This is what your problem will look like:
-(-7.1) + 7.49
7.1 + 7.49 = 14.59
