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
Step-by-step explanation:
5 log₅ x − ¼ log₅ (8−x)
log₅ x⁵ − log₅ (8−x)^¼
log₅ x⁵ − log₅ ∜(8−x)
log₅ (x⁵ / ∜(8−x))
Answer:
Step-by-step explanation:
There are a couple of ways to solve this, depending on what you already know.
Point-Slope Form
where <em>m</em> is the slope and 
is a point on the line.
First, calculate the slope using the two given points 
.
.
Fill in the point-slope pattern
There's the equation in slope-intercept form (
).
Slope-Intercept Form
Use directly.
Find the slope just like the above, so 
.
Now, plug one of the points (either one!) together with <em>m</em> into
Now you know the value of <em>b</em>, so the equation for the line is
