Answer:

The inequality representing the situation is 0.75x+0.45y\geq 5.70

Step-by-step explanation:

Let x represent the 75-cent stamps.

Create a polynomial with zeros: x = {-2,3}<br> I have no idea how to do this
aliya0001 [1]

Standard form of polynomial = ax² + bx + c

Zeros: x = {-2,3}

This gives the factors as, (x + 2) (x - 3)

On expanding this:

(x + 2) (x - 3)

x(x - 3) + 2(x - 3)

x² - 3x + 2x - 3

x² - x - 3

Polynomial = <em>x² - x - 3</em>

Gina shows the steps she took to find the solution of the inequality below.
Leviafan [203]

Answer:

hello,2 th made from the wrong place.

because She should have distributed the -2 inside the parentheses.

the process should be like this;

19-2(1-x)<13

17(1-x)<13

17-17x<13

-17x<13-17 (17 goes to the opposite side as -17)

-17x<-4 (we divide each side by 17)

x= -4/-17

I hope you understand. There are errors in the first 2 parts of the question.
