So what you do you divide 8000 by 30 and should get 266.6 gallons were wasted
Y = (x - 6)/4
to find the inverse of a function, you swap the x and y variables, then solve for y.
y = (x - 6)/4 ... swap x and y
x = (y - 6)/4 ... solve for y, start by multiplying both sides by 4 to cancel out your denominator
4x = (y - 6) ... add 6 to both sides
4x + 6 = y
your inverse function is y = 4x + 6
Answer:
I'm sorry I'm not sure but try d
Answer:
0
<em>Quick </em><em>Tip</em>
<em> </em>X - value on the y - axis is always 0.
f(x) is used interchangeably with y
፡ f(x) = y
y = 5.
Answer:
14ft/sec
Step-by-step explanation:
GIVEN: An automobile traveling at a rate of 30 ft/sec is approaching an intersection. When the automobile is 120 ft from the intersection, a truck traveling at the rate of 40 ft/sec crosses the intersection.
IN SKETCH BELOW............. IN THE ATTACHMENT
A IS AUTOMOBILE AND V IS TRUCK AT TIME T= 0
TRUCK IS AT M AFTER T SECONDS...AUTOMOBILE IS AT L AFTER T SECS.
AT=120 '
After T seconds
AL= 30T
LV= 120-30T
VM= 40T
LM =
( let this be s)
now , ds/dt = 

now in this equation put T=2 we get

ds/dt= 1400/100= 14 FPS
hence the two vehicles are separating at 14 ft/sec at T=2 seconds
