Answer:
slope = -
Step-by-step explanation:
Differentiating implicitly with respect to x
2x + 2y = 0
2y = - 2x
= - = -
is the measure of the slope of the tangent
rearrange equation to find corresponding y-coordinate of x = - 2
y² = 16 - 4 = 12 = 2 ⇒ y = ± 2
using x = - 2, y = - 2, then
= - = -

Answer:
$350
Step-by-step explanation:
you would divide 120 by 2 because it is $120 for 2 hours.
you would get 60. then u would multiply 60 by 5, which is 300. Then u add an extra $50 because that was the cost of just the appointment.
