Question

if a bass has a length of x inches, where x is between 20 and 25 inches, its weight can be estimated by the formula W(x)=0.96x-14.4.
a)what length of bass weighs 6.8 pounds?
b)what lengths of bass weigh less than 6.8 pounds?
i dont even know where to start...

Answer 1

ur answers must be between 20 and 25

W(x)=mass="pounds"

Answer 2

i still dont know where to start ive tried putting those values in the equation for x but the answers i get are unrealistic

Answer 3

ur given the mass 6.8
ur equation W(x)=0.96x-14.4
since W(x) = mass when x value is used
so
6.8=0.96x-14.4
solve for x

Answer 4

ok i got 22.1. i think what i was doing wrong was putting the x value in for both x's in the equation

Answer 5

Lol....

Answer 6

Answer 7
