<span>So you have to take the derivative first of 9x^2+16y^2=52.
18x + (32y)(y') = 0
32y (y') = -18x
y' = -18x / 32y
plug in for 0, to find the slope which will get you - 9/16.
and you know that the tangent of the line formula is y - y1 = m (x -x1), and the problem gave you the points for y1 and x1.
so the line tangent is y = - 9/16 (x - 2) - 1
I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

Answer:
3+(axb)
Step-by-step explanation:
Answer:
-2 > x
Step-by-step explanation:
-8x-10>7x+20
Add 8x to each side
-8x+8x-10>7x+8x+20
-10 > 15x+20
Subtract 20 from each side
-10 -20 > 15x+20-20
-30 > 15x
Divide by 15
-30/15 > 15x/15
-2 > x
