3(5y + 6) - 4
First, expand to get rid of parentheses.
Second, leave the 15y be and subtract 18 - 4 to get 14.
Answer:
15y + 14
Answer:
4.2223
=42,223/10,000
If you divide (6x +3) by (x +1) you get some quotient and some remainder. You can do it a variety of ways, including synthetic division and long division. The method used here is to rewrite 6x+3 as a multiple of x+1 with some constant term added.
.. 6x +3 = (6x +3) +3 -3
.. = (6x +3 +3) -3
.. = (6x +6) -3
.. = 6(x +1) -3
Now, you can divide this by (x +1) and you have
Then the boxes can be filled from ...
You know that
.. f(x) +6
represents a translation of f(x) by 6 units up
And you know that
.. f(x +1)
represents a translation of f(x) by 1 unit left
So, you can figure that
.. g(x) = f(x +1) +6
will represent a translation of 1 unit left and 6 units up of f(x) = -3/x.
Plug in 3 for "y":
7x + 2y = 48
7x + 2(3) = 48
2*3 = 6
7x + 6 = 48
Then, you have to subtract 6 to both sides..
7x = 42
Divide 7 to both sides and the your answer would be 6
