Answer:
A) (-6, 8)
B) (x, y) ⇒ (-x, y)
Step-by-step explanation:
B) The rule for reflection across the y-axis is that the x-coordinate changes sign:
(x, y) ⇒ (-x, y)
__
A) To find the pre-image point, one can simply reflect the image back across the y-axis:
A'(6, 8) ⇒ A(-6, 8)
Negative exponets are like normal ones
ex. 2^-2=-4 another way to do it 2^-2=2^2 with a - so you can do 2^2=4 add the - and it becomes -4.
ABC is similar to PQR
that means AC/PR is a constant = 12/ 6 = 2
AC= 2 PR
AB= 2PQ
BC= 2QR
Perimeter of ABC= AB+BC+ CA=
2PQ + 2 QR + 2PR= 2( PQ+ QR+ PR)
= 2( perimeter of triangle PQR )
Perimeter of ABC= 2( perimeter of PQR) = 2* 36 = 72
Answer : 72.
No. 4/3 or 4 divided by three is not the same as 3/4 or three fourths. 4/3 is 1.33333333333. 3/4 is .75
I’m pretty sure it C) 13
Have a great day
