Answer:
No
There are infinitely many solutions to the system.
{36x+21y=24312x+7y=81
Multiply the second equation by 3.
3(12x+7y36x+21y=81)=243
Subtract this new equation from the first equation.
36x+21y−(36x+21y0+0=243=243)=0 true
Answer: 3 + 7i
Step-by-step explanation:
Equation expanded: 12 + 5i - 9 + 2i // now simplfy
12 - 9 = 3
5i + 2i = 7i
// together, we get
3 + 7i

How many times can 5.18 get into 16.8?
Its going to be represented as a decimal:
Answer:
A
Step-by-step explanation:
We are given two functions:

And we want to find:

Thus:

We can factor the denominator of the first term:

In order to add the two terms, we must have a common denominator. To achieve this, we can multiply to second term by (x - 4). Therefore:

Multiply:

Combine:

Simplify:

We can expand the denominator:

Therefore, our answer is A.
The simplified version is: 7z-29y+18
Hope this helps :)
