2(3 + 9x) - 2x
= 6 + 9x - 2x <----------------mistake right here
= 6 + 7x
Correct:
Expanding by using distributive property
2(3 + 9x) - 2x
= 2* 3 + 2 * 9x - 2x
= 6 + 18x - 2x
= 6 + 16x
The best answer is <span>inconsistent. </span>
6x^4-17x^3-7x^2+13x=3
6x^4-17x^3-7x^2+13x-3=3-3
6x^4-17x^3-7x^2+13x-3=0
y=6x^4-17x^3-7x^2+13x-3
y=0
The solutions are: x=-1, 1/2, 1/3 and 3
Looking at the numbers, we can see that the differences are 72, 36, and 18. Notice that they are each factors of the next by the same constant 2.
18 * 2 = 36
36 * 2 = 72
There, it means that 18/2 will be subtracted from 20.
20 - 18/2
= 20 - 9
= 11
The next number in the sequence would be 11. Hope this helps!
Answer:
1)
Step-by-step explanation:
In the line that is the graph of equation x = 2, every ordered pair has 2 as its x-coordinate. That means it's a vertical line that passes through x = 2 on the x-axis.
