The coordinates of point T are (14,21). The midpoint of is (7,-8). Find the coordinates of point S.

Anestetic [448]

Answer:

S(7, -37)

Step-by-step explanation:

Let the coordinates of point S be (x, y).

(14 + x)/2 = 7

14 + x = 14

x = 0

(21 + y)/2 = -8

21 + y = -16

y = -37

Still need help on this please need help

Goryan [66]

The discriminant is the value of b²-4ac
in this case, b=-8, a=4, c=4, so the discriminant is (-8)²-4*4*4=0
when the discriminant is 0, there is one rational solution.
when the discriminant is larger than 0, there are two rational solutions.
when the discriminant is smaller than 0, there are no real solutions. <span />

What’s 3x+6y=12 in the form y=mx+b

zhenek [66]

Hey there!

3x+6y=12

Divide both sides by 3 and your equation would now look like:
x+2y= 4
Move the x to the other side
2y= -x+4
Seprate the y by dividing both sides by 2
y= $\frac{1}{2}$ x+2
