Answer:
the answer is 50
Step-by-step explanation:
3x - 2y = 5
-2x + 2y = -2
--------------------add
x = 3
3x - 2y = 5
3(3) - 2y = 5
9 - 2y = 5
-2y = 5 - 9
-2y = -4
y = -4/-2
y = 2
solution is (3,2)
ur system of equations is : 3x - 2y = 5 : -2x + 2y = -2
Answer:
B. 54
Explanation:
Take 72 from 180.
180 - 72 = 108.
Since there are two y's AND they're congruent, divide 108 by two and get 54.
Answer:
$15,339
Step-by-step explanation:
C(x) = 0.5x² − 100x + 20,339
Since this is a parabola, the minimum cost is at the vertex:
x = -b / (2a)
x = -(-100) / (2 × 0.5)
x = 100
So the minimum cost is:
C(100) = 0.5(100)² − 100(100) + 20,339
C(100) = 15,339
