Answer:
b
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 1, 2) and (x₂, y₂ ) = (3, 1)
m =
= -
, thus
y = -
x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 1, 2), then
2 =
+ c ⇒ c = 2 -
= 
y = -
x +
← in point- slope form
Multiply through by 4
4y = - x + 7 ( add x to both sides )
x + 4y = 7 → b
Answer:
It's polyhedron, not polygon
Because above figure has merely 10 sides.
so the polyhedron above has 10 sides, each of them has 20°.
so total degree in polyhedron is > 180(n-2)
>180(10-2)
> 180×8
> 1440

Hope it helps you
Ok so I’m not sure but here’s what I would do to solve it
There is only one x so
X+
5.1+3.2=8.3
So
X+8.3 is the answer
