Look for what 'y' is when t = 1 and t = 2. Go to the graph, look at 1 on the bottom axis and go up till you find the point, then go all the way to the left to see what the y-value is, in this case it should be 1200. If you do the same with t = 2, you will get 2400. So our two ordered pairs are:

(1, 1200), (2, 2400)

We can find the slope of these two points by plugging them into the slope formula:

\sf m=\dfrac{y_2-y_1}{x_2-x_1}

For points in the form of (x1, y1), (x2, y2). Plug in what we know:

\sf m=\dfrac{2400-1200}{2-1}

Subtract:

\sf m=\dfrac{1200}{1}

Divide:

\sf m=1200

This is the slope, so we can write the equation:

\boxed{\sf y=1200t}

What are rational numbers and how do you tell the difference between integers? Please answer what are rational numbers first.
Maslowich

1. A rational number is a number that can be written as a fraction.

For example: 1/3, 5/7, 90/666, etc

Note: Any integer can be written as a fraction.

Look:

5 = 5/1 = rational

-14 = -14/1 = rational

2. There is no difference between a rational and integer.

There may be multiple answers here. please help
gogolik [260]
I'm not positive I know the answer, but I have a feeling that because it's asking that you select all that apply, there is more than just one answer.

x + 3 = 0
-3 + 3 = 0

So yeah, just basically solve them as individual problems. Just do additive inverse for each expression.

A= 12.8m<br> B=13.9m<br> C=12m<br> D= 7m
Bogdan [553]

Answer:

C: 12m

Step-by-step explanation:

We can solve this by using the Pythagorean Theorem a^{2} + b^{2} = c^{2}

For this triangle

a= x   b= 5   c= 13

We now have the equation

x^{2} + 5^{2} =13^{2}

If we simplify this we get

x^{2} + 25 = 169

Next, we subtract 25 from both sides

x^{2} = 144

Finally, if we take the square root of both sides of the equation, we find that

x= 12
