Company A: <span>a one time $100 fee and $50 for each tree
</span>c = 100 + 50t
Company B: <span>one time $80 fee and $60 for each tree
</span>c = 80 + 60t
answer is {c=100+50t c=80+60t (last choice)
0.308
Explanation
The probability of an event is the number of favorable outcomes divided by the total number of outcomes possible,so
so
Step 1
favourable outcome is the result that is desired, so as the result is a that Raphael purchase the ticket
a) Let
and , the total outcome is the total ticket,so
b) now, replace in the formula:
therefore,the answer is 0.308
I hope this helps you

Answer: 2/9</h3>
====================================================
Explanation:
The equation y = (2/9)x is in the form y = kx
In this case, k = 2/9.
The value of k is the constant of proportionality.
All direct proportion equations are in the form y = kx. Their graphs go through the origin. The slope of the line is the same as the constant of proportionality.
So for this problem, you have to cross multiply, numerator to denominator.
11 * 2x = 2x+5 * 12
22x = 12(2x+5)
22x = 24x+60
-24x -24x
-2x = 60
Divide both sides by -2
X = -30
Composition means that you can plug g(x) into f (x). This is written as "( f o g)(x)", which is pronounced as "f-compose-g of x". And "( f o g)(x)" means " f (g(x))". That is, you plug something in for x, then you plug that value into g, simplify, and then plug the result into f. hope this helps.
