Answer:
y = x + -2.3
x = -y - 2.3 (but why would one need this?...)
Step-by-step explanation:
(6.1 - (-9.7))/(8.4 - (-7.4)) = 15.8/15.8 = 1
6.1 = 8.4 + b
b = -2.3
Answer:
-1.2
Step-by-step explanation:

Subtract 3.9 from -9.18 to isolate the variable.

Divide -13.08 by 10.9

Which equals

2 solutions, the root to the equation is the same as the root to the solution also known as “double roots”
Answer:
(2x-3)(-3+2x),(16-x^2)(x²-16),4y^2+25)(25+4y^2)
Step-by-step explanation:
I know that the rest of the products didn't make a perfect square cause they don´t aren´t squared,I also know that they are the odd ones out among the rest of the product so yeah,I am not too sure if I got it right...sorry if I didn´t.
