I think its sec theta
i havent done this in a while so... its prob wrong
Inverse
replace f(x) wih y
solve for x
replace x with f⁻¹(x) and y with x
so
f(x)=3x+5/7
replace
y=3x+5/7
solve for x
minnus 5/7 both sides
y-5/7=3x
divide both sides by 3

=x
replace with f⁻¹(x)
f⁻¹(x)=
Answer. The standard form of a line is in the form Ax + By = C where A is a positive integer, and B, and C are integers. Hope this helps, let me know if it’s correct so others can use it :)
Good luck.
Answer:
$35.50
Step-by-step explanation:
55.50-48= 7.5
