Answer:
2x - 2y = -8
x + 2y = -1
3x = -9
x = -3
-3 + 2y = -1
2y = 2
y = 1
(-3, 1) is the solution

You can do this !
The rectangular prism has
-- length = 10 cm
-- width = 7 cm
-- height = 3 cm.
-- The area of the top and bottom is (length x width) each.
-- The area of the left and right sides is (length x height) each.
-- The area of the front and back is (width x height) each.
There. I just laid out all the schmartz you need to answer this question.
The rest is all simple arithmetic, and you're perfectly capable of turning
the crank and getting the answer. You don't need anybody else to do
that part for you.
Don't forget your units. The area of each flat face is (cm) times (cm),
and that product will be some cm² , for area.
Answer:
or
Step-by-step explanation:
We are going to see if the exponential curve is of the form:
, ().
If you are given the intercept, then is easy to find.
It is just the coordinate of the intercept is your value for .
(Why? The intercept happens when . Replacing with 0 gives . This says when .)
So .
So our function so far looks like this:
Now to find we need another point. We have two more points. So we will find using one of them and verify for our resulting equation works for the other.
Let's do this.
We are given is a point on our curve.
So when , .
Divide both sides by 8:
Reduce the fraction:
So the equation if it works out for the other point given is:
Let's try it. So the last point given that we need to satisfy is .
This says when , .
Let's replace with 2 and see what we get for :
So we are good. We have found an equation satisfying all 3 points given.
The equation is .
