If y varies directly as x and y=288 when x=16 determine the value of y when x-13
Ray Of Light [21]
Y = kx is the direct variation equation
Substitute the x and y that are given to find k then write your new equation in terms of y with the k.

288 = k(16) divide by 16 to find k
18 = k
Now write the new equation
y = 18x

y = 18(13) or y = 18(-13) I'm not sure by what you have typed if that is supposed to be and equal sign or a negative.
y = 234 OR y = -234

Find the inverse function f -1(x) for the given function f(x). f(x) = x + 1/8
velikii [3]

Answer:

f⁻¹(x) = 8x - 1

Step-by-step explanation:

Swap the positions of y (f(x)) and x and solve for y.

x=\frac{y+1}{8}\\\\8(x)=\frac{y+1}{8}(8)\\\\8x=y+1\\\\8x-1=y+1-1\\\\8x-1=y
