The answer is A because the same rule applies
Is This Substitution?
Cause if it is, then Y = 3x - 4
Y = 4 + x
= (4, 8)
Answer with Step-by-step explanation:
We are given that an equation of curve

We have to find the equation of tangent line to the given curve at point 
By using implicit differentiation, differentiate w.r.t x
Using formula :



Substitute the value x=
Then, we get


Slope of tangent=m=
Equation of tangent line with slope m and passing through the point
is given by

Substitute the values then we get
The equation of tangent line is given by




This is required equation of tangent line to the given curve at given point.
I guess maybe 5/35 because there are only 5 chances that you could get one of the 5 in the 35 people
Answer:
x = 20
Step-by-step explanation:
The 3 arcs UV, VW, WX form a semicircle, so sum to 180° , that is
4x + 2 + x + 78 = 180
5x + 80 = 180 ( subtract 80 from both sides )
5x = 100 ( divide both sides by 5 )
x = 20
