What is the answer?
Bad White [126]

Answer:

k=3

Step-by-step explanation:

+ we note f(p)= p^{4}+p^{2}  +p -k

+ Because of "p-1 is a factor of f(p)", that means f(p)= (p-1)* g(p)

Then we have f(1)= (1-1)*g(1)= 0* g(1)= 0

+ We replace p=1 in f(p) and we have:

f(1)=0

that means: 1^{4}+1^{2} + 1 - k=0

then 1+1+1-k = 0, 3-k=0 or k=3

Hope that useful for you.

Do i need to flip the reciprocal please explain your answer<br> 2y/2 &lt; 10/2
saul85 [17]

Answer:

\displaystyle \large \boxed{y < 5}

Step-by-step explanation:

We are given the Inequality:

\displaystyle \large{ \frac{2y}{2}  <  \frac{10}{2} }

First, we can simplify the expression. On the left side of Inequality, we can cancel 2; on the right side, we can cancel 2 out as well.

Simply, division!

\displaystyle \large{ \frac{ \cancel{2}y}{ \cancel{2}}  <  \frac{ \cancel{10}}{ \cancel{2} }}

2 divides 2 is 1; 2 divides 10 is 5.

\displaystyle \large{ \frac{1y}{1}  <  \frac{ 5}{ 1}}

Generally, it is not recommended to write 1 beside the variable nor write 1 as a denominator.

Simplify the expression:-

\displaystyle \large{ y  <  5}

Therefore, the value of y is less than 5.

Let me know if you have any questions after reading the explanation!
