— 3х – 2y = 16<br> х+ 9y = 28

Alla [95]

Answer:

x=-8

y=4

Step-by-step explanation:

first you multiply this equation (-3x-2y=16) with negativ it will be like this 3x+2y=-16

3x+2y=-16

(x+9y=28)3 _multiply with 3

3x+2y=-16

3x+27y=84

use minus(-) =3x-3x=0

=2y-27y=-25y

=-16-84=-100

the result:-25y=-100

y=4

take any simple equation and replace y with 4

x+9y=28

x+9(4)=28

x+36=28

x=28-36

x=-8

answer:x=-8,y=4

Write the equation of a circle with endpoints of the diameter are (-8, 1) and (4,5)

STatiana [176]

centre of the circle =Midpoint of the diameter

centre of the circle=

$( \frac{ - 8 + 4}{2} , \frac{5 + 1}{2} ) = ( - 2 ,3)$

radius of the circle=

$\sqrt{(4 - ( - 2) ^{2} + (5 - 3 )^{2} } = \sqrt{36 + 4} = \sqrt{40 } = 2 \sqrt{10}$

equation of the circle: (x+2)²+(y-3)² = 40

ie.. x²+4x+4+ y²- 6y+ 9=40

ie... x²+y²+4x-6y-27=0

this is the answer......
