The answer is 40 is 80% of 50
Answer:
-5
Step-by-step explanation:
Each time the x value goes up 1, the y value goes down 5.
change in x = 1
change in y = -5
slope = (change in y)/(change in x)
slope = -5
Step-by-step explanation:
The point-slope form of an equation of a line:
m - slope
(x₁, y₁) - given point
Answer:
A, B, C, and E
Step-by-step explanation:
y = 4x - 20
8x - 2y = - 20 (divide everything by 2)
4x - y = -10
-y = -4x - 10
y = 4x - 10
4x - 10 = 4x - 20
0 -10

The expression 1.5 x 1.09^t models the housing costs, in thousands of dollars, for summer term t years since Chinedu applied to his college.
Now In general we have the following rule for exponential functions:
Here we have two cases for b:
Case 1: if b<1 , we call it as exponential decay.
Case 2: if b>1 , we call it as exponential growth.
Now let us compare our equation with this general form,
1.5 x 1.09^t
Here b is 1.09, which is greater than 1.
So here we can say that the housing cost is increasing exponentially by a factor or 1.09.
