Hello there! Given the expression, we can solve through a series of steps:
1. Simplify
-5 + 7 • 1
2. Multiply (according to order of operations)
7 • 1 = 7
3. Add
-5 + 7 = 2
Your final answer is 2. Hope this helps!
Answer:
a = 5120
b = 1.25
Step-by-step explanation:
Let the exponential function representing the given table is,
f(x) = 
Here, f(x) = Number of views
x = Number of weeks
We choose two points from the given table and satisfy the equation of the function.
Let the points are (0, 5120) and (1, 6400)
For a point (0, 5120),
f(0) = a(b)⁰ = 5120
a = 5120
Now for the second point (1, 6400),
6400 = 5120(b)¹
b = 
b = 1.25
Therefore, a = 5120 and b = 1.25 are the values.
13.5/3 = 4.5
