Answer:

x=-6, y=-8. (-6, -8).

Step-by-step explanation:

8x-5y=-8

-7x-5y=82

---------------

-(8x-5y)=-(-8)

-7x-5y=82

---------------------

-8x+5y=8

-7x-5y=82

---------------

-15x=90

x=90/-15

x=-6

8(-6)-5y=-8

-48-5y=-8

5y=-48-(-8)

5y=-48+8

5y=-40

y=-40/5

y=-8

Triangle XYZ is reflected about the y-axis. What are the coordinates of X’?

Dominik [7]

Just flip the signs of co-ordinates by using formula y=>-y

Make sure to do this with y only as it has been reflected to y axis

$\\ \ast\bull\rm\longmapsto Z(-5,-4)\implies Z'=(-5,-(-4))\implies Z'=(-5,4)$

$\\ \ast\bull\rm\longmapsto Y(-3,-4)\implies Y'=(-3,-(-4))\implies Y'=(-3,4)$

$\\ \ast\bull\rm\longmapsto X(-5,-1)\implies X'=(-5,-(-1))\implies X'=(-5,1)$

VARVARA [1.3K]

V(-5;-2)
$f(x)=a(x+5)^2-2$

$x=-4$ . $y=2$

$2=a(-4+5)^2-2$
$2=a*1-2$
$2=a-2$
$a=4$
