Write the inequality in interval notation X is greater than or equal to negative 4

Here is our inequality.
x \geq -4

Let's go from least to greatest, and add in infinity as our maximum.
-4 \leq x \ \textless \  \infty

Our interval notation would look like this.
[-4,\ \infty)
We put the lower bound, then the higher bound, using brackets instead of parentheses if x can also be equal to that value.

To finance a bridge costing $94,500, the state contributed twice as much as the county and the county contributed twice as much
bearhunter [10]
The city contributed $13,500; the county contributed $27,000; and the state contributed $54,000.

Let x be the amount the city contributes.  Since the county contributes twice as much as the city, the county's amount is 2x.  Since the state contributes twice as much as the county, the state's amount is 2(2x) = 4x.

They total 94,500:
x+2x+4x = 94500
7x = 94500

Divide both sides by 7:
x = 13500
2x = 27000
4x = 54000

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>
