1. (7x+3)(4x−5) =
multiply everything by each other than combine like terms
= 28x^2-23x-15
2. 49x^8−16y^14
rewrite 49x^8 as (7x^4)^2, rewrite -16y^14 as -(4y^7)^2
then factor to get (7x^4 +4y^7)(7x^4 -4y^7)
3. 7x^2+16x+4 = (7x+2)(x+2)
Answer:
(x,y) -> (x, -y)
Step-by-step explanation:
This is a reflection about the x-axis.
Algebraically, it can be represented by:
(x,y) -> (x, -y)
since the position along the x-axis does not change, and the y-coordinates are flipped about the x-axis, therefore flipped in sign.
