Answer:
Step-by-step explanation:
First rule I'm going to use is the quotient rule:
Secondly, I'm going to rewrite the radical.
Third, I'm going to use the product rule on the first term:
Fourth, I'm going to use power rule for both of the last two terms:
Answer:
The y-coordinate of their intersection point is 3
That is y=3
Step-by-step explanation:
Given two lines are y=6x+15 and y=mx+4
Given that the two lines intersect at x=-2
To find the y coordinate of their intersection point :
Equating the two lines
6x+15=mx+4
6x+15-mx-4=0
6x-mx+11=0
(6-m)x+11=0
At x=-2 (6-m)x+11=0
(6-m)(-2)+11=0
(6-m)(-2)=-11
Substitute the value in y=mx+4 we get
At x=-2
Therefore y=3
Therefore the y-coordinate of their intersection point is 3
