In six years you will have 84% to get that mutiply 14×6 and there you have 84%
Answer:
y = 192
Step-by-step explanation:
Given y varies directly as z and inversely as x then the equation relating them is
y =
← k is the constant of variation
To find k use the condition y = 16 and z = 2 when x = 42
k =
=
= 336
y =
← equation of variation
When x = 14 and z = 8, then
y =
= 192
f(x) = 2x + 1
To find the inverse, f^-1(x), of the function:
Put the function as an equation:
y = 2x + 1
Then move x to the left and y to the right;
x = 2y + 1
Then solve for y;
y = x/2 - 1/2
f^-1(x) = y
f^-1(x) = x/2 - 1/2
x = 9/2
Get variable on one side of equation and solve"
x/12 = 3/8
x = (3/8)(12)
x = 9/2
