Answer:

<em>=10x^2+8x+3</em>

Step-by-step explanation:

Lets simplify step by step.

=5x^2+3x+4+5x^2+5x+-1

Combine like Terms.

=5x^2+3x+4=5x^2+5x=-1

=(5x^2+5x^2)+(3x+5x)+(4+-1)

=10x^2+8x+3

<u><em>=10x^2+8x=3</em></u>

prisoha [69]

Answer:

0.33

Step-by-step explanation:

To solve this example we use this rule :

Δx/Δy

x is amount that changed. so Δx=0,99.

How we get 0.99.

Our storm is to 3 to 6 so we find difference for x : for 3rd and 6th member of table... 3.88-2.89=0.99

Now we have :

0.99/Δy

Because we need to find from 3 to 6 , Δy=3 ,

When we find both, we can find rate of change with :

0.99/3=0.33
