I mark brainliest for all my questions that are answered right :) thx for helping me

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

:D

The answer is 63.!
