A polynomial p has zeros when I = 0.2 = -
Rainbow [258]

Answer:

p(x) = (5x - 1) (x + 3)

Step-by-step explanation:

I apologize if I couldn't answer correctly, the question was a bit hard to understand because of the formatting.

Also I didn't see my answer in the list of answer choices but here it is:

if the polynomial has zeros at 0.2 and -3 the equation would have to be:

p(x)=(x-0.2)(x+3)

This is because plugging either of those numbers into the polynomial would cause it to equal 0.

(x-0.2) can be simplified by multiplying everything in the parenthesis by 5, getting rid of all of the decimals, making the final answer:

p(x) = (5x - 1) (x + 3)

-3 1/2x - 4 = -38 1/8<br><br> How do I do this?
abruzzese [7]

Hello, I will try my best to explain this to you as simple as possible.

First, you have to pass the -4 to the other side, like this:

-3 1/2x - 4 = -38 1/8

              ↓

-3 1/2x = -38 1/8 - 4

Then, you have to subtract -4 from -38 1/8, like so:

-3 1/2x =  -38 1/8 - 4

              ↓

-3 1/2x = -42 1/8

My preferred method for this next step is this:

-3 1/2x = -42 1/8

              ↓

-7/2x = 337/8

Then, we divide:

-7/2x = -42 1/8

              ↓

x = (-337/8) / (-7/2)

x = 12.0357142857

So, the answer is: 12.0357142857.

Hope this helped! c:

lbvjy [14]
In this question, lindy rounds the population correctly.
The numbers 831,982 and 800000 are both six- digit numbers. But 83000 is a five- digit number.
And 831,982 rounded to nearest lakh is 800000.
