Yes those answers are correct
Answer:
x = -3
Step-by-step explanation:
the lines in the form:
y = a , where a is a constant is a horizontal line
and
x = b, where b is a constant is a vertical line
To find lines that are parallel to the horizontal and vertical lines with point given (n,p), we follow the rule below:
1. If we have a line y = a and goes through point (n,p), the parallel line will have equation y = p
2. If we have a line x = b and goes through the point (n,p), the parallel line will have equation x = n
<em><u>Now, this question gives a vertical line x = -11 and we need to find line parallel to this that goes through (-3,9). So, from RULE #2 above, we can say the parallel line's equation would be:</u></em>
x = -3
Answer:
For part 1:
-2x^6 + 7x^4 + 3x^3 - 3x^2 + 11x + 20
For part 2:
Based on the foiling of both, they are equal.
Step-by-step explanation:
(-2x^3 +x -5)( x^3 -3x-4)
What we need to do is foil one by one.
I’ve attached a picture of this.
Once you foil, you add like terms.
Now for part 2, x^3 -3x-4 and -2x^3 +x -5, we do the same process.
