It's "all values except 4". 4 is a vertical asymptote and the function does not exist there at all. But the left side comes in from negative infinity and goes down to negative infinity, and on the right it comes down from positive infinity, but since it's getting closer and closer to the horizontal asymptote of y = 0, it's decreasing there too.
The Answer is:
(5a2-3a+8)+(-4a2-1)+(15a+11)
Perpendicular means the slopes are opposite inverse of each other
If line a is slope 2, the perpendicular line to Line a would have a slope - 1/2
Difference in y over difference in x gives slope. If they are opposite inverse values the lines are perpendicular. ( in this case the answer is true.)
together = add
add the fractions
3 7/10 + 5 9/10
add the whole numbers first
3+5=8
add the fractions
7/10+9/10= 16/10
8 16/10
reduce 16/10 divide by 2
16/2= 8
10/2= 5
8 8/5
whole number changes to 9
8-5=3
denominator stays the same
9 3/5
Answer:
9 3/5
