N/d = 15
d= 4 + 3n
d=n/15
n/15=4+3n
n=60+45n
44n=-60
n=-15/11
-15/11 / d = 15
-15/11 = 15d
d=-1/11
15/11 / 1/11. = 15
Answer:
y = -
x + 3
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 ) = (0, 3) and (x₂, y₂ ) = (4, 0) ← 2points on the line
m =
= - 
Note the line crosses the y- axis at (0, 3 ) ⇒ c = 3
y = -
x + 3 ← equation of line
180-2(55)-x=0
180-110-x=0
70-x=0
-x=-70
x=70°
By AAS congruency the two triangles are congruent
Answer:
This is a linear function.
