Answer:
C
Step-by-step explanation:
Under a reflection in the line y = x
a point (x, y ) → (y, x ) , thus
Q(- 5, 2 ) → Q'(2, - 5 )
R(0, 5 ) → R'(5, 0 )
S(- 1, 2 ) → S'(2, - 1 )
Due to the Triangle Angle Sum Theorem, we know that the sum of the interior angles of a triangle equals 180 degrees, therefore,
180 = m<1 + m<2 + m<3
180 - m<3 = m<1 + m<2
But, we also know that m<4 + m<3 = 180 degrees.
180 = m<3 + m<4
180 - m<3 = m<4
Both m<4 and m<1 + m<2 equals 180 - m<3
m<4 = m<1 + m<2
Answer:
C(x)=25x+6000
b=2250
Step-by-step explanation:
C(x)=mx+b
m-marginal cost
x-no items
finding B
C(x)mx+b
6000=25(130)+b
b=2250
General substitution
C(x)=25x+6000
42600-25800=16800
16800/15=1120
42600*x=100*1120
x=112000/42600=2.62%
