Answer:
k = –10
Step-by-step explanation:
From the question given above, the following data were obtained:
f(x) = x³ – 6x² – 11x + k
Factor => x + 2
Value of K =?
Next, we shall obtained the value of x from x + 2. This is illustrated below:
x + 2 = 0
Collect like terms
x = 0 – 2
x = –2
Finally, we shall determine the value of k as illustrated below:
f(x) = x³ – 6x² – 11x + k
x = –2
Thus,
f(–2) = 0
x³ – 6x² – 11x + k = 0
(–2)³ – (–2)² – 11(–2) + k = 0
–8 – (4) + 22 + K = 0
–8 – 4 + 22 + K = 0
10 + k = 0
Collect like terms
k = 0 – 10
k = –10
Thus, the value of k is –10
its y2-y1 over x2-x1 and you plug in 4 and 8 for x1 and x2 and then 61 and 108 for y1and y2
Answer:
The answer is y=-3/5x-6
Step-by-step explanation:
y-y=m(x-x1)
y-(-3)=-3/5(x-(-5))
y+3=-3/5x-3
-3 -3
y=-3/5x-6

×22
=124
+1240
=1364
her answer is not responsible because how can 124+1240=1,042
