f(x) = (3x+5)/7
Step 1:
we write f(x) as y
y=(3x+5)/7
Step 2:
switch y by x and x by y
x=(3y+5)/7
Step 3:
solve for y,
x=(3y+5)/7
multiply both sides by 7
7x=3y+5
subtract 5 from left side
3y=7x-5
divide both sides by 3
y= (7x-5)/3
f⁻¹ (x) =(7x-5)/3
Answer:
7xx4
Step-by-step explanation:
Answer:
55
Step-by-step explanation:
Its not that hard actually if you break down the exponents and then multiply and add them all together.
Answer:
see, you take 3y to the other side it becomes 4x=12+3y. then you take out the 4 from X and divide it by 12+3y. so it becomes 12+3y/4
