DEF= 6 ft^2

A= 1/2*b*h

Plug in what you know.

6= 1/2*4*h

Multiply like terms.

6=2*h

Divide 2 on both sides.

3=h

If the base of ABC= 12

12/4=3

3*3=9

A= 1/2*b*h
A= 1/2*12*9
A= 1/2*84
A= 42

The area of ABC is 42 ft^2

I hope this helps!

What is the reflection of point P(−1, 6) across the line y = x?

zhannawk [14.2K]

ANSWER

P'(6,-1)

EXPLANATION

The mapping for a reflection in the line y=x is

The line y=x is the mirror line for a function and it's inverse.

$(x,y)\to (y,x)$

The x and y coordinates swap position.

The reflection of point P(−1, 6) across the line y = x is

P'(6,-1)
