Answer:
y=7x+11
Step-by-step explanation:
to find the slope we need to do 
which is 
or 7.
then, we put this into point slope form (y-y1)=m(x-x1).
y-4=7(1)
we make the x value 0 in order to find the y-intercept.
y=11 since we multiply 7 by 1 to get 7, and add 4 onto both sides.
then we put the slope and the y-intercept into slope intercept form and get y=7x+11.
A regular decagon has 10 equal sides. An apothem is a perpendicular bisector to the side. This means 2 equal right triangle are formed on each side (20 equal right triangles) or 10 equal isosceles triangles.
Using the 10 equal isosceles triangles and A = .5(base)(height)
Base is a side and height is apothem
Area of regular decagon = 10 × .5 × 8 × 12.3 = 492.0 yd²
Answer: 492.0 yd²
Answer:
The Area of a Segment is the area of a sector minus the triangular piece (shown in light blue here). There is a lengthy reason, but the result is a slight modification of the Sector formula: Area of Segment = θ − sin(θ) 2 × r2 (when θ is in radians) Area of Segment = ( θ × π 360 − sin(θ)2 ) × r2 (when θ is in degrees)

Answer:
x=10
Step-by-step explanation:
4x-18=3x-8
4x-3x=-8+18
x=10
