I did this quiz
Answer:
Infinitely many solutions
Step-by-step explanation:
When the solved system has the same number on each side, the system has infinite solutions.
Answer:
a = 80
b = 3/4
the general equation is;
y = 80•(3/4)^x
Step-by-step explanation:
Here, we want to get the values of a and b
We are going to use the two points given
(0,80) and (1,60)
So we have this as;
for the first point;
80 = a•b^0
anything raised to power of 0 is 1
Thus;
80 = a * 1
a = 80
for the second point;
60 = 80 * b^1
60 = 80b
b = 60/80
b = 3/4
So we have the general equation as;
y = 80•(3/4)^x
Answer:
-11/12
Step-by-step explanation:
I can not show the steps because there are a lot and when I used my calculator, I got -11/12. :)
Alright, as we can see the large rectangle's area is 4x² + 9x + 2.
You can also see that gray rectangle's area inside the larger rectangle is
x² + 4x + 3.
So if we want to find the white area in-between the two rectangles we will need to SUBTRACT the two formulas! (Subtract the large rectangle from the smaller one)
To do so we will need to subtract the like terms.
The like terms are 4x² and x², 9x and 4x, 2 and 3!
So first we do 4x² - x² and you get 3x²
Next, we do 9x - 4x and you get 5x
Lastly, we do 2 - 3 and you get -1
Now we put our solutions together and you get...
3x² + 5x - 1
This is the are for the white region of your problem. :D glad to help
