Answer:
i think i need a 4 choice, because they are easier
Step-by-step explanation:
As you know, the domain is the values "x" can safely take on.
well, for a logarithmic expression, it can never have an expression of 0, namely in this case, x + 4 must never be 0, since such a logarithm doesn't exist.
now, x + 4 = 0 ---> x = -4.
thus if "x" ever becomes -4, we'd end up with log₃(-4+4), or log₃(0), which is a no dice.
so the domain is all values except -4.
Answer:
There are 37 white marbles.
Step-by-step explanation:
Let the white marbles be represented as w.
Let the yellow marbles be represented as y.
The bag contains both white marbles and yellow marbles which add up to 46 marbles. This means that:
y + w = 46 ___________(1)
The number of white marbles is 1 more than 4 times the number of yellow marbles. This means that:
w = 1 + 4y ___________(2)
First, we find y by putting (2) in (1), thereafter, we find w:
=> y + 1 + 4y = 46
y + 4y = 46 - 1
5y = 45
y = 45 / 5 = 9 marbles
=> w = 1 + 4(9)
w = 1 + 36 = 37 marbles
There are 37 white marbles.
Its is 900 because 120 divided by 8 is 15 and 15 times 60 is 900
