Answer:
y = -3/5x + 1.3
Step-by-step explanation:
y = mx + b
m: slope
b: y-intercept
First, let's substitute in the values.
Point: (2, 1)
Slope: -3/5
y = mx + b
(1) = (-3/5)(2) + b
1 = -0.3 + b
1 + 0.3 = -0.3 + b + 0.3
b = 1.3
Now, let's add the slope and y-intercept to the equation.
y = mx + b
m = -3/5
b = 1.3
y = -3/5x + 1.3

Exponential functions represent the initial value outside of the parentheses so if 2 is the initial value it has to be on the outside of the parentheses.

Step-by-step explanation:
8.4%/100% x 5000 = interest
(5000 x 12) + (interest x 12)
= investment worth
(7,4) they’re both positive numbers
We can do it with the equation written; we'll try that next. I find it easier to remember the exterior angles, which are the supplements of the interior angles, add to 360 degrees.
The exterior angle is 180 - 144 = 36 degrees. n = 360/36 = 10
Answer: 10 sides
Let's try it your way now.
![\dfrac{180(n-2)}{n} = 144](https://tex.z-dn.net/?f=%5Cdfrac%7B180%28n-2%29%7D%7Bn%7D%20%3D%20144)
![180n-360 = 144 n](https://tex.z-dn.net/?f=180n-360%20%3D%20144%20n)
![36n = 360](https://tex.z-dn.net/?f=36n%20%3D%20360)
![n = 10 \qquad\checkmark](https://tex.z-dn.net/?f=n%20%3D%2010%20%5Cqquad%5Ccheckmark)
