the vertices of triangle PQR are P(-3, 8), Q(-6, -4), and R(1, 1). If you reflect triangle PQR across the x-axis, what will be t

Answer:

The coordinates of the vertices of the image will be:

P'=(-3,-8)

Q'=(-6,4)

R'=(1,-1)

Step-by-step explanation:

If you reflect a point P=(x,y) across the x-axis, the coordinates of the image will be P'=(x,-y), then:

P=(-3,8)=(xp,yp)→xp=-3, yp=8→P'=(xp,-yp)→P'=(-3,-8)

Q=(-6,-4)=(xq,yq)→xq=-6, yq=-4→Q'=(xq,-yq)=(-6,-(-4))→Q'=(-6,4)

R=(1,1)=(xr,yr)→xr=1, yr=1→R'=(xr,-yr)→R'=(1,-1)

How do you do this? Please help, I’ve been staring at this for like 10 min :)

damaskus [11]

Answer & Step-by-step explanation:

The formula is given in the middle. You are supposed to insert the value of x into this formula to find the value of y (like in the first given example):

$x=-2\\y=2(-2)+5\\y=-4+5\\y=1$

------

$x=-1\\y=2(-1)+5\\y=-2+5\\y=3$

------

$x=0\\y=2(0)+5\\y=0+5\\y=5$

------

$x=1\\y=2(1)+5\\y=2+5\\y=7$

------

$x=2\\y=2(2)+5\\y=4+5\\y=9$

Solve this and get 12 points

Pachacha [2.7K]

Answer:

Step-by-step explanation:

First, find x. Since x is the average of the three number, add the three up and then divided by three. Thus:

$x=\frac{13+-16+6}{3}=3/3=1$

y is the cube root of 8. Thus:

$y=\sqrt[3]{8}=2$

So:

$x^2+y^3\\=(1)^2+(2)^3\\=1+8=9$
