So this would be F(-9)=-(-9)(2)-10(-9)-2 --------
9(2)-10(-9)-2 ----------- 18+90-2 ----------- 108-2+ 106.
So the answer to this equation is 106.

St. Augustine grass can grow at the rate of 4 over 7 centimeter per week.
kotegsom [21]

Given, the rate of growth of St. Augustine grass is \frac{4}{7} cm per week.

We have to find the number of weeks that the grass grow to \frac{12}{7} cm.

Let's take the number of weeks be x.

In 1 week the grass grow = \frac{4}{7} cm

So in x weeks the grass grow = (\frac{4}{7}) (x) =\frac{4x}{7} cm

So we can write,

\frac{4x}{7} =\frac{12}{7}

To solve it for x, first we will move 7 to the right side by multiplying it to both sides. We will get,

(\frac{4x}{7}) (7) =(\frac{12}{7})(7)

4x =(\frac{12}{7})(7)

4x = 12

Now to get we will move 4 to the right side by dividing it to both sides. We will get,

\frac{4x}{4} =\frac{12}{4}

x = 3

So we have got the required answer.

After 3 weeks the grass grow \frac{12}{7} cm.
