Answer:
rise over run
Step-by-step explanation:
you look at the distance between the 2 points by looking at how many points its goes up or down, and you look at how points it goes from the left to the right or vice versa. but if you don't have a graph to look at, you will want to use the slope formula. look up the slope formula and plug it in.
Answer:
x = -8
Step-by-step explanation:
-2.5x - 2 = 18.
Add 2 to both sides.
-2.5x = 20.
Divide both sides by -2.5.
x = -8
The equation will be of the form:

where A is the amount after t hours, and r is the decay constant.
To find the value of r, we plug the given values into the equation, giving:

Rearranging and taking natural logs of both sides, we get:


The required model is:
Answer:
80
Step-by-step explanation:
180-(60+40)=180-60-40=180-100=80
To triple this number, you can triple the whole number, triple the fraction, then add them together.
3*3=9
1/2*3=3/2 (or 1 1/2)
Add them together.
9+1 1/2= 10 1/2
