What the composite function in the question is actually trying to explain is;
First of all, in the function 
, we will find a result by writing 
where we see the letter 
.
We will write this result in the 
function where we see the letter and we will get the result.
point slope form = y-y1 = m(x-x1)
y-2 = 3(x-1)
distribute
y-2 = 3x-3
add 2 to each side
y = 3x-1
this is in slope intercept form
Answer:
30.40/3.2=9.5 so he pays $9.50 per ounce of steak
Step-by-step explanation:
Answer:
Turtle = 11 m / min
Snail = 1 m / min
Total approach speed = 12 m/min
360 m / (12 m/min) = 30 min
Separation is 30 min at assumed speed of 1 m/min
But we know the separation is 40 min
So turtle moves at 3/4 * 11 m / min = 33 m/ 4 min
Snail moves at 3/4 * 1 m /min = 3/4 m / mi
Total approach speed = (33 + 3) / 4 = 9 m / min
So in 40 min
9 m / min * 40 min = 360 m
(Leaving out those units, they approach at 12 * unit of speed)
So the unit of speed has to be 360 m / 40 min = 9 m / min
