Answer: 34
Step-by-step explanation:
Substitute n with 9
-14+3(9-1)(2)
-14+3(8)(2)
= 34
r(x) = –x² + 3x
s(x) = 2x + 1
(s – r)(x) is simply the difference of these functions. Subtract r(x) from s(x):
(s - r)(x) = s(x) - r(x)
(s - r)(x) = 2x + 1 - (-x² + 3x)
(s - r)(x) = 2x + 1 + x² - 3x
(s - r)(x) = x² - x + 1
The answer is the last option
Answer:
k = 28/7 which equals 4
Step-by-step explanation:
1/2k + 6 = 4k - 8
1/2k - 4k = -8 - 6
1/2k - 8/2k = -14
-7/2k = -14
k = -14 * - 2/7
k = 28/7 which equals 4
