Answer:
The equation is 
The slope is m=-4
Step-by-step explanation:
we know that
The linear equation in slope intercept form is equal to

where
y is the amount left in the saving account
x is the number of weeks
m is the slope or unit rate of the linear equation
b is the y-intercept or initial value
In this problem we have
The slope is equal to
--> is negative because is a decreasing function
The y-intercept or initial value is

substitute

In order to find the value of g(4)+f(-3), we must substitute those values into the functions first.
Substitute -3 into f(x).
f(x)=x²
f(-3)=(-3)²
f(-3)=9
Substitute 4 into g(x).
g(x)=2x-3
g(4)=2(4)-3
Using the rules of PEMDAS, multiply first then subtract.
g(4)=8-3
g(4)=5
Therefore, if f(-3) is 9 and g(4) is 5, we must add the two values together.
5+9=14
<u>The value of g(4)+f(-3) is 14.</u>
