Write an exponential function to represent a person consuming a bag of candy in which the initial value in an is 175 pieces and

Alisiya [41]

We will see that the exponential decay function is:

f(x) = 175*(0.8)^x

<h3>How to find the exponential decay?</h3>

The general exponential decay is:

f(x) = A*(1- r)^x

Where:

A is the initial value.
r is the rate of decay in decimal form.
x is the variable, in this case is the time.

Here we know that the initial value is 175, and the rate of decay is 20%. To get this in decimal form, we just divide it by 100%.

20%/100% = 0.2

Replacing that in the exponential function, we get:

f(x) = 175*(1 - 0.2)^x

f(x) = 175*(0.8)^x

Which point can be found using the vertical line x = –9 and the horizontal line y = 8?

Fudgin [204]

ANSWER

The point is
$(-9,8).$

EXPLANATION
When two nonparallel lines are drawn on the same plane, they will intersect at a unique point. This point represents the solution to the two systems of equations represented by the lines.

The vertical line
$x = - 9$

and the horizontal line
$y = 8$

will intersect at
$(-9,8).$

This is the unique solution to the two equations.
