Yes you can divide fractions using models here is an example
Answer:
x = -1/2
Step-by-step explanation:
This question can be solved by applying the laws of indices
In a^n, a - base
n - index
Given
9^x = 1/3
According to the laws of indices, a/b = b^(-a)
Hence we can write, 1/3 = 3^(-1)
9^x = 3^(2x)
Again according to the laws of indices,
a^b = a^n can be written as;
b = n
That is, if in an equation the bases are the same, the indices are also equal.
So we can write,
3^(2x) = 3^(-1)
2x = -1
Divide both sides of the equation by 2, the coefficient of x
2x/2 = -1/2
x = -1/2
Answer: Its b
Step-by-step explanation:my teacher told me
A relation is the relationship between variables. When each input has one output, the relation is a function. When the value of k is 5 or 3, the relation will not be a function.
Given that:
For S, not to be a function, 1 domain element must point to more than one range elements.
This means that:
Collect like terms
Multiply by -1
Remove absolute bracket
Solve for k
Hence, when k is 5 or 3, the relation will not be a function.

<span>-3(-w - u) - (-5 + w)
=-3(-w-u)+-1(-5+w)
=-3(-w-u)+(-1)(-5)+-1w
=-3(-w-u)+5+-w
Distribute
=(-3)(-w)+(-3)(-u)+5+-w
=3w+3u+5+-w
Combine like terms
=3w+3u+5+-w
=(3u)+(3w+-w)+(5)
=3u+2w+5
