Answer:
14.5x + 25
Step-by-step explanation:
note that (C + R)(x) = C(x) + R(x), thus
C(x) + R(x) = 2.5x + 25 + 12x = 14.5x + 25
Y = x² + 1
y = x + 1
x² + 1 = x + 1
<u> - 1 - 1</u>
x² = x
x² - x = 0
x² + 0x - x - 1 = 0
(x - 1)(x + 0) = 0
x - 1 = 0 or x + 0 = 0
<u> + 1 + 1</u> <u> - 0 - 0</u>
x = 1 x = 0
