Answer:
k = 5
Step-by-step explanation:
Given that (x + 1) is a factor of f(x) then f(- 1) = 0
f(- 1) = 3(- 1)³ + 2(- 1) + k
= 3(- 1) - 2 + k
= - 3 - 2 + k
= - 5 + k
Then - 5 + k = 0 ( add 5 to both sides )
k = 5

Answer:
y = -5
Step-by-step explanation:
-10(-1/2y + (-7/2)) + 7y = -25
Let's first of all expand the bracket to get;
5y + 35 + 7y = -25
12y + 35 = -25
12y = -25 - 35
12y = -60
y = -60/12
y = -5
