Answer:
y=1
x=-5
Step-by-step explanation:
3x+y=-14
4x+4y=-16
y=-3x-14
4x+4y=-16
y=-3x-14
4(-3x-14)+4x=-16
y=-3x-14
-8x-56=-16
y=-3x-14
-8x=40
y=-3x-14
x=-5
y=1
x=-5
The average rate of change over the interval
is 2.17
Explanation:
Given that the cost of a floral bouquet after a discount is given by the function 
We need to determine the average rate of change over the interval 
The average rate of change can be determined using the formula,

where
and 
Substituting the value of a and b in the function, we get,






Hence, substituting these values in the formula, we get,

Simplifying, we get,

Dividing, we have,

Thus, the average rate of change over the interval
is 2.17
