Answer:
Lucy needs to invest $55,194.16
Step-by-step explanation:
If the exponential function 
passes through the points (3,25) and (8,10), the value of b is 0.833
The given exponential equation is:
The function passes through the points (3, 25) and (8, 10)
Substitute x = 3 and y = 25 into the function
............................(1)
Substitute x = 8 and y = 10 into the function
.............................(2)
Divide equation (2) by equation (1)
Therefore, if the exponential function passes through the points (3,25) and (8,10), the value of b is 0.833

Answer:
No
Step-by-step explanation:
To obtain the inverse function
let y = f(x) and rearrange making x the subject, that is
y = 3x + 1 ( subtract 1 from both sides )
y - 1 = 3x ( divide both sides by 3 )
= x
Change y back into terms of x, thus
(x) = 
Answer:
y = 1/2x -1.5
Step-by-step explanation:
The equation of a line is typically written as y = mx + b.
m is the slope of the line, while b is the y-intercept. y is the y-coordinate and x is the x-coordinate.
Since it indicated that the line has a slope of 1/2, we can substitute the m in the equation with 1/2.
y = 1/2x + b
In order to find the intercept of the line, we use the equation of a line to substitute the y-coordinate and x-coordinate of (-3,-3) to discover the y-intercept of b.
-3 = 1/2(-3) + b
One half of -3 is -1.5.
-3 = -1.5 + b
Add -1.5 to both sides of the equation.
-3 = -1.5 + b
+1.5 +1.5
-1.5 = b
Since we found the y-intercept, we can now place it into our equation.
y = 1/2x -1.5 and that's the answer!
