1/2 y +6 = x
y=2 (x-6)
= 2x-12
f^-1 (x)= 2x-12
8x + 26 = 98
8x = 72
x = 9
8x + 26 + z = 180
8(9) + 26 + z = 180
72 + 26 + z = 180
98 + z = 180
z = 82
Answer:
I think its y^-3
Step-by-step explanation:
Since y^-3/y^-2 are both negatives they would swap places to become positive - y^2/y^3
then using rules of exponents you would subtract the exponents witch would be y^-3
I think the answer is 60 and 30 but I'm on break so I'm not thinking rn
You multiply 3.14 by the diameter or 2 times the radius
for area you do pi or 3.14*radius squared
