Answer:
x= - 1
Step-by-step explanation:
Y = 12.1% x 13 + 351
y= 0.012 x 13 + 351
y= 1.573 + 351
y= 352.573 or $352.6
the opposite is squared so,
square root of 4 is 2 and 2 squared is 4
Ok, a fun hack
if f⁻¹(a)=b then f(b)=a
so if f⁻¹(7)=b then f(b)=7
to find b, find x such that f(x)=7
7=0.5(3)^x
times both sides by 2 (or divide both sides by 0.5)
14=3^x
take log₃ of both sides

Answer:
The answer is 21/35 or 3/5
Step-by-step explanation:
35-14=21
