It's given in the question that both the traingles JCD & JKL are similar. So their ratio of corresponding similar sides will be proportional to each other.

$= > \frac{JD}{JL} = \frac{JC}{JK} = \frac{DC}{LK}$

$= > \frac{15}{50} = \frac{8 + x}{60} = \frac{DC}{LK}$

$= > \frac{15}{50} = \frac{8 + x}{60}$

$= > 8 + x = \frac{15 \times 60}{50} = 18$

$= > x = 18 - 8 = 10$

What is the inverse of the function f(x) = 1/4x - 12?

madam [21]

Hello,

y=1/4 x-12
x=1/4 y -12 (exchange x and y)
1/4y=x+12
y=4(x+12) solve for y
y=4x+48
