Answer:
a.
b.
Step-by-step explanation:
To solve this question, we apply implicit differentiation.
xy = 2
Applying the implicit differentiation:
a. Find dy/dt, when x = 4, given that dx/dt = 13.
x = 4
So
Then
b. Find dx/dt, when x = 1, given that dy/dt = -9.
x = 1
So
Then
A is the answer to your question
Answer:
1.) supplementary m<1+m<2=180 and m<2+m<3=180
2.) congruent, supplementary
Step-by-step explanation:
the answers are in this order above
Ok so u have to set them equal to 180 bc they r supp lines so 1.15+x=180 sub 15 from both sides x=165
2.28+x-4=180 combine like terms 28-4=24 rewrite 24+x=180 den sub 24 from both sides x=156
I will put the rest in the comments if you still don't know
