It gained 4 lbs:) 6*4 = 24
24+12 = 36
Negative rate of change just means that the graph is falling. On this one, that's everywhere after x=0.5. The only choice that's completely in that section is the last one.
Answer:

Step-by-step explanation:
You can only add radicals if the value inside the square root symbol is the exact same, therefore, this one is 6. To find the sum, we can add the values outside the square root symbol (3 and 4) to get our new radical.
We can also check this.
≈ 7.35
≈ 9.8
≈ 17.15
7.35+9.8 = 17.15
Hope this helped!
Answer:
Slope = $4.00
y - intercept = $0.50
y = 4x + 0.5
Step-by-step explanation:
Given :
Cost of Mini blizzard = $4.00
Cost of optional or additional topping = $0.50
A linear model is in the form:
y = mx + b
For this scenario
y = total cost of order
m = slope Coefficient = cost of mini blizzard
x = number of mini blizzards ordered
c = additional cost, cost of candy topping
Hence, rate of change, slope, m = cost of mini blizzard = $4.00
The y - intercept = cost of candy topping = $0.50
Six now have a good day happy face bye-bye
