Mathematics
1 answer:
lorasvet [3.4K]3 years ago

Answer:

The value of k is 1.

Step-by-step explanation:

x – 1 is a factor of f(x)

This means that:

x - 1 = 0

x = 1

That means that when x = 1, y = 0. We use this to find the value of k.

f(x) = 3x^3 - 4x + k

3*1^3 - 4(1) + k = 0

3 - 4 + k = 0

k = 1

The value of k is 1.

By what number should-15/56 be divided to get -5/6<br><br>pls pls pls pls I need your help ​
mr_godi [17]

Answer:

The desired divisor is n = 21

Step-by-step explanation:

Let that number be n.  Then:

-15/56        -5

---------- = ---------

     n            6

Through cross-multiplication we get:

(-15/56)*6 = -5n, which reduces to:

(-15)(7) = -5n, or 3(7) = n

The desired divisor is n = 21
