Vertex

we have

f(x)=x²-18x+88

let

y=x²-18x+88

comparing above equation with ax²+bx+c

we get

a=1

b=-18

c=88

now

vertex(x,y)=(-b/2a,f(-b/2a))

x=(18/2×1)=9

y=f(9)=9²-18×9+88=7

VERTEX(X,Y)=(9,7)

△ABC is reflected to form △A'B'C' .

eduard

Answer:

Option A is correct

reflection across the x-axis

Step-by-step explanation:

The rule for reflection across x-axis is given by:

$(x, y) \rightarrow (x, -y)$

As per the statement:

The coordinate of triangle ABC are:

A(−4,−3) , B(−7,1) and C(−1,−1).

The coordinate of triangle A'B'C' are:

From the given diagram we have;

A'(-4, 3), B'(-7, -1) and C'(-1, 1)

Apply the rule of reflection across x-axis on ABC we have;

$A(-4, -3) \rightarrow (-4, -(-3))=(-4, 3)=A'$

$B(-7,1) \rightarrow (-7, -1)=B'$

$C(-1,-1) \rightarrow (-1, -(-1))=(-1, 1)=C'$

Therefore, the reflection results in the transformation of △ABC to △A'B'C' is, reflection across the x-axis

6. Find the coordinates of A if M-1, 2) is the midpoint of AB and B has coordinates of (3.-5).

AlekseyPX

Answer:

A(-5,9)

Step-by-step explanation:

Let A(a,b)

Since M is the midpoint then of A(a,b) and B(3,-5) then

M( (a+3)/2 , (b-5)/2)

But it is given that M(-1,2)

So (a+3)/2 = -1 which implies a=-5

and (b-5)/2=2 which implies b=9.

Therefore A(-5,9)
