Mathematics

Triss [41]3 years ago

Answer:

The value of polynomial for x = 2 that is f(2)  will be 32  

Step-by-step explanation:

We have given polynomial f(x)=3x^2+8x+4

We have to find the value of f(2)

We have to find the value of polynomial for x = 2

So for finding this value we have to just put x = 2 in polynomial

So f(2) will be f(2)=3\times 2^2+8\times 2+4=32

So the value of polynomial for x = 2 will be 32

When u=-2, put that in where you see "u". use parentheses.
-4(-2)+4x=12

-4*-2=8 ➡positive 8 since a negative times a negative is always positive
一一一一一
now look for x
8+4x=12
subtract 8 from both sides. get x by itself.

-8+8+4x=12-8
4x=4➡ divide both sides by 4. a number divided by itself is 1 (unless one side is negative, then the answer is negative)
4/4=1

slava [35]

Answer:

Graph in attachment and Solution set is x € (⅕ ,-∞)

Step-by-step explanation:

We need to graph the solution of a inequality . For graph refer to the attachment . Let's solve out and find the solution set of inequality .

=> 5/3x < 10

=> 5 < 10 * 3x

=> 5 < 30 x

=> 5 /30 < x

=> x > 1/5

Basically we need to plot here x > 1/5 . The solution set will be , x € ( 1/5 , -∞ )
