Answer:
y= 1
Step-by-step explanation:
primero tienes que subtituir 3 en la x 2×3+y=7
6+y=7
-6. -6
y=1
Let the complex number be x + iy
Then by the pythagoras therem
17 = x^2 + y^2
D will satisfy this equation
4^2 + (-1)^2 = 17
answer is D 4 - i
Answer:
third person

Answer:
Angles that are congruent and have the same value
Step-by-step explanation:
Answer:
The correct answer is 10 for lowest average cost and the cost function is 0.2
+ 75x + 20.
Step-by-step explanation:
Average cost function is given by =
= C(x) = 0.2x +
+75.
For minimizing we need to find
C(x) = 0.
⇒
C(x) = 0.2 -
.
⇒
= 0.2
⇒
= 100.
⇒ x = ±10
⇒ x = 10 ; cost cannot be negative.
Second order derivative is positive which implies the average cost minimizes.
Original cost function is given by C(x) × x = 0.2
+ 75x + 20.
