Answer:
Step-by-step explanation:
If the boy initially had 20 cents, then the total number of cents he will have left after purchasing 
pencils is equal to the total cost of the pencils subtracted from 20. The total cost of pencils, in cents, is equal to 
, since each pencil is 3 cents.
Therefore, the total amount, in cents, that the boy has left, 
, is equal to 
:
The domain of this function is 
or all real numbers 
.
Answer:
3y
Step-by-step explanation:
First find the factors of the terms. You need to then figure out how many factors match.
-9y² = -1 · 3 · 3 · y · y
6y = 2 · 3 · y
3y is the greatest common factor.
Answer: probability distribution is a function of a discrete variable whose integral over any interval is the probability that the random variable specified by it will lie within that interval.
Answer:
x=2.5&.5
Step-by-step explanation:
The quadratic formula is (-b+or-sqrt(b^2-4ac)/2a
12+or-sqrt((-12^2)-4(4)(5))
12+or-sqrt(144-80)
12+or-sqrt(64)
(12+8)/8 and (12-8)/8
x=2.5 and x=.5
1.) Isolate a variable.
2.) Subsitube
3.) then solve for other varible.
