Answer:
5/10
Step-by-step explanation:
for every girl picked a boy is also picked. There are 10 kids so it's a 50% chance it happens
5/8=15/x
cross multiply and divide to find x.
8*15=120
120/5=24
You would need 24 drops of yellow

5.11111111111 is your answer
Step-by-step explanation:
Step-by-step explanation:
here is the answer for your question
<span>Your equation is:
f(x) = 7x - 2
Solve for x.
Add 2 to both sides of this equation to get:
f(x) + 2 = 7x
Divide both sides of this equation by 7 to get:
(f(x) + 2)/7 = x
Since, in general, a = b implies that b = a, this equation becomes:
x = (f(x) + 2)/7
Replace x with f(x) and replace f(x) with x to get:
f(x) = (x+2)/7
That's your inverse function.
Graph both your function and your inverse function.
Set y = f(x) to get:
y = 7x - 2 (your regular function).
y = (x+2)/7 (your inverse function).
Graph also the function y = x.
