Find the inverse of y=7x-10. Is the inverse a function?
2 answers:
Answer: 
(x) = 
Step-by-step explanation:
To find the inverse , all we need do is to make x the subject of the formula.
y = 7x - 10
Add 10 to both sides
y + 10 = 7x
divide both sides by 7
Therefore:
x = y + 10 / 7 , that is
(x) =
Answer:
Step-by-step explanation:
y=7x-10 calculate x : 7x-10 =y
7x = y+10
x = 1/7 y +10/7
the inverse of y=7x-10 is ; y = 1/7 x +10/7

A) For object with mass m1,
F = m1 * 3
m1 = F/3
For object with mass m2,
F = m2 * 1
m2 = F
Ratio of m1/m2
(F/3) / F = 1/3
