here is a spreadsheet to help you understand the stair problem notice for 1 step 1 block, 2 step, 3 block, 3 step, 6 block and so on notice the blocks for the number of a step is that step plus all the other blocks needed to make all the one(s) below it. Notice it takes 105 blocks to make 14 steps.
So if you are familiar with the summation process you would add the number that go with that stair with all the stairs below it. example step 5 blocks would be 5 + 4 + 3 + 2 +1 or 15 blocks. I hope this gets you started. The second part I do not understand the problems because they are not equations. NO equal signs
glad if it helps
Answer:
21/20
Step-by-step explanation:
a) One hour is equivalent to 60 minutes.
So we can multiply 50 minutes by the fraction 
, so we could convert 50 minutes to hours.
It is:
If we simplify the fraction, we have:
b) In order to express the turtle's speed in miles per hour, we have to divide
by 
So:
We simplify the expression by multiplying 7 mile by 6 and 8 by 5 hours:
Given the function 
1. Translation to the right 1 unit changes the function 
into the function 
2. Translation 2 units down changes the function 
into the function 
3. Two translations change the funcion into the function
4. The graph of the final function you can see in attached diagram.
