If Kong took a 85 second and we if Nolan took 15 slower then Nolan took a 72.25 second test. First you would find 14 percent of 85 then that is 12.75. Minus that from 85 and you get 72.25.

Hope It helps!

find the equation of the straight line passing through the point (0,-1) which is perpendicular to the line y=-3/4x-3

barxatty [35]

Answer:

y = $\frac{4}{3}$ x - 1

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

y = - $\frac{3}{4}$ x - 3 is in this form

with slope m = - $\frac{3}{4}$

the slope of a perpendicular line is the negative reciprocal of m, hence

$m_{perpendicular}$ = $\frac{4}{3}$

(0 , - 1 ) is the y-intercept ⇒ c = - 1

y = $\frac{4}{3}$ x - 1 ← equation of perpendicular line
