I answered this before and explained this but the answer is 3π I think. Hope this helps
So we have the equation:

Then we need to multiply by 4 on both sides to get rid of the denominator on the left:

Then we subtract 9 on both sides to solve for z:

Therefore the answer is z = -0.6.

In ∆MKP and ∆MNP
MK = MN
PK = NP
MP = MP
SO ∆MKP AND ∆MNP ARE CONGRUENT.
SO m<PMN = m<PMK
m<NMK = 50
=> m<PMN + m<PMK = 50
=> 2 m<PMK = 50
=> m<PMK = 50/2 = 25°
Answer:
The equation of the line is -4x + y = 3
Step-by-step explanation:
Since we have the slope, we can use it and either point in point-slope form and solve for the standard form of the equation.
y - y1 = m(x - x1)
y - -1 = 4(x - -1)
y + 1 = 4(x + 1)
y + 1 = 4x + 4
-4x + y + 1 = 4
-4x + y = 3
