Answer:
10x - 3y = -109 .
Step-by-step explanation:
x^2 + y^2 = 109
Implicit Differentiation:
2x + 2y.y' = 0
y' = -2x/2y = -x/y
So at the point (-10,3) the gradient of the tangent is -(-10)/3 = 10/3.
Equation of the tangent:
y - y1 = m(x - x1)
y - 3 = 10/3(x + 10)
y - 3 = 10/3 x + 100/3
3y - 9 = 10x + 100
-109 + 3y = 10x
10x - 3y = -109

Hi my lil bunny!
❀ _____.______❀_______._____ ❀
Let's solve your equation step-by-step.
![(\frac{2}{3}x) ( \frac{-6}{7} + \frac{4}{5}) = [\frac{\frac{2^x4}{3} }{5} ] ( \frac{-6}{7} )](https://tex.z-dn.net/?f=%28%5Cfrac%7B2%7D%7B3%7Dx%29%20%28%20%5Cfrac%7B-6%7D%7B7%7D%20%2B%20%5Cfrac%7B4%7D%7B5%7D%29%20%3D%20%5B%5Cfrac%7B%5Cfrac%7B2%5Ex4%7D%7B3%7D%20%7D%7B5%7D%20%5D%20%28%20%5Cfrac%7B-6%7D%7B7%7D%20%29)
Step 1: Subtract 
from both sides.
Step 2: Factor left side of equation.
Step 3: Set factors equal to 0.
So the answer is : x = 0 or x = - 0.759836 or x = 0.759836

Hope this helped you.
Could you maybe give brainliest..?
Answer:
i) 7x + 8 = -90
<=> 7x = -98
<=> x = -98/7
<=> x = -14
ii) 5y - 4 = 2y - 25
<=>3y = -21
<=> y = -21/3
<=> y = -7
iii) 4(p + 3) = 36
<=> p + 3 = 36/4
<=> p + 3 = 9
<=> p = 9 - 3
<=> p = 6
iv) 2 (4f + 3) = 3 (2f + 6)
<=> 8f + 6 = 6f + 18
<=> 2f = 12
<=> f = 12/2
<=> f =6
Hope this helps!
:)
