Answer:
y= 
Step-by-step explanation:
To find inverse of something, just switch the variables
x=y^2
now try to solve back in terms of y
y= 
In this problem, you must change the signs of everything in the parenthesis, which will come to 3x^2 + x - 5x^2 - x + 4. Add like terms, and you will end up with -2x^2 + 4, which is answer choice A. Hope this helped
Answer:
C. Integer

Answer:
Hi there!
Your answer is:
Y= 0
X= 9
Step-by-step explanation:
3x=27+3y
3x-10y=27
Solve one of them for Y
I chose the first equation
3x=27+3y
-27
3x-27=3y
/3
x-9 = y
NOW, plug y in the second equation!
3x-10y=27
y= x-9
3x-10y=27
3x-10(x-9) = 27
Solve for x!
3x-10x+90 = 27
-7x + 90 =27
-90
-7x = -63
/-7
x= 9
FINALLY, plug back in x for y equation
y=x-9
x=9
y=9-9
y=0
