Find the midpoint of the segment with the given endpoints. (9,9) and (-1,- 3)

GenaCL600 [577]

Answer: (4, 3)

Step-by-step explanation:

The formula for coordinate of the mid point is given as :

Mid point = ( $\frac{x_{2}+x_{1}}{2}$ , $\frac{y_{2}+y_{1}}{2}$ )

$x_{1}$ = 9

$x_{2}$ = -1

$y_{1}$ = 9

$y_{2}$ = -3

Substituting the values into the formula , we have :

Mid-point = ( $\frac{-1+9}{2}$ , $\frac{-3+9}{2}$ )

Mid-point = ( $\frac{8}{2}$ , $\frac{6}{2}$ )

Mid - point = ( 4 , 3)

If x2 + y2 = 38 and x - y = 2, then what is x? If there are two possible answers, then enter the larger of the two.

Ket [755]

If x-y=2 then x=2+y

And if you insert that in the first equation

$(2 + y) {}^{2} + y {}^{2} = 38$
$4 + 4y + y {}^{2} + {y}^{2} = 38$
$2y {}^{2} + 4y - 34 = 0$
$y = - 1 + \sqrt{17}$
Or
$y = - 1 - \sqrt{17}$

The first one is bigger so the answer is

$y = - 1 - \sqrt{17}$
