Frank can do 150 push-ups in 2 minutes
explanation: 40 x 3 = 120 = 2 minutes
50 x 3 = 150 = 150 push-ups
Answer: Great you got your answer correct
Step-by-step explanation:
Hello!
This question is an example of function notation. Function notation is basically f(x) , said as "f of x". To solve this problem, you need to substitute x = 2 into each x-value in this equation. F(2) is written as function notation, while x = 2 is not.
F(2) = 4x² - 3x + 5
F(2) = 4(2)² - 3(2) + 5
F(2) = 4(4) - 6 + 5
F(2) = 16 - 6 + 5
F(2) = 15
Therefore, the value of F(2) is 15.
Answer:
Step-by-step explanation:
The cost per sandwich when 3 are delivered is $20/3 or $6.67 each.
The cost per sandwich when 4 are delivered is $26/4 or $6.50 each.
The average cost per sandwich changes with the number delivered, so it is not proportional. The cost decreases per sandwich as the volume of sandwiches increases. One can't predict the cost of 6 delivered sandwiches based on the information provided. If it were proportional, the cost could be calculated on the basis of the slope of the line. If all sandwiches cost $6.50 each, regardless of the volume ordered, the slope of a line relating number ordered and total cost would have a constant slope of 6.50. That isn't the case in this problem. The slope keeps changing.
