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

Write the equation of a line in - form that contains the point (- 1, - 2) and is perpendicular to the line y = 5x - 10 degrees
galina1969 [7]

Answer:

y+2= -1/5(x+1)

Step-by-step explanation:

if lines are perpendicular their slopes are negative reciprocal

y=mx+b where m is the slope

y=5x-10 has the slope 5 so a perpendicular line will have slope -1/5

equation point slope form

(y-y1) = m(x-x1) where m is slope, and (x1,y1) any point that belongs to the line

y+2= -1/5(x+1)

oee [108]

Answer:

-2

Step-by-step explanation:

to find the slope from to points you can follow this equation

m=y2-y1 / x2-x1

so plug in the points

1-3/ 1-0

-2/1

-2

Emeril solved this equation using the steps shown below:
ExtremeBDS [4]

Answer:

Step 2: He should have added 3 to, rather than subtracting 3 from, both sides.

Step-by-step explanation:

1. Combine like terms: 6b − 3 = −21  

2. Subtraction property of equality: 6b = −24  

Here he has to add 3 on both sides, to isolate the variable term.

Therefore, answer is Step2)  He should have added 3 to, rather than subtracting 3 from, both sides.

Hope this will helpful.

Thank you.
