The correct answer is y= 0.513(1.833)^x
Explain
We will use the equation on this form
Y=ab^x
Let’s us plug in the coordinates of first point
(X, y) , ( 9, 120)
We will have
Y=ab^x
120= ab^9
Our equation for a will be
Ab^9 = 120
ab ^9 / b^9 = 120/ b^9
a = 120/ b^9
So will have
Y= 120/ b^9 • b^x
Then we will plug in coordinates for the second point
( x,y) = ( 10, 220)
We will have
Y= 120/b^9 • b^x
220 = 120/b^9 • b^10-9
220= 120b
Divide both side by 120
B= 11/6
B= 1.833333 = 1.833
Let’s plug in the value b=11/6 to our equation for a
A= 120/b^9
A= 120/ 11/6^9
A= 120/11^9/6^9
A=120 • 6^9 / 11^9
= 0.51285 which equal to 0.513
So therefore the answer is
Y= 0.513(1.833)^x
I hope this help you

Answer:9
Step-by-step explanation:
Remember that the y-intercept is where the function has a value of
and the x-intercept is where the function has a value of
. Thus, to find the x-intercept and y-intercept, we can substitute these values into the equation and solve for the other variable.
<u>x-intercept</u>
Since the x-intecept has a y-value of 0, we can substitute this into the function and solve for
.



The x-value of the x-intercept is
and the y-value is 0, meaning that the x-intercept has coordinates
.
<u>y-intercept</u>
Since the y-intercept has a x-value of 0, we can substitute this into the equation and solve for
:


The y-value of the y-intercept is -3, meaning that the y-intercept of the function is
.
Okay, I got no clue what’s going on but okay
Answer:
Rise over run
Step-by-step explanation:
Take two points where you know for sure the coordinates (in this problem, you can use (2, 1.5) and the origin). Find the difference between the two y's for your run, and between your two x's for your rise. Then, put it in a fraction (it needs to be a fraction, thus the name rise over run.)
