Use DESMOS and then take the points that are given and then plug them into your equations to show your work.
Desmos helps all equation problems that you need solved because it not only solves it, but also has it graphed with marked points.
It helped me through highschool.
-32
Step-by-step explanation:
Step 1:
The rate of change over an interval is got by finding the change in g(x), the change in x and dividing it.
Step 2:
Given, x denotes the number of miles walked by Marcus for the fund raiser
g(x) denotes the amount of money he has left to raise after x miles of walking
g(x) for the interval [6,10] is 408,280
Change in x = 10-6 = 4
Change in g(x) = 280-408 = - 128
Rate of change = -128/4 = -32
Hence the average change in rate over the given interval is -32
Answer: The piano has 222 strings, because 37×6=222.
Step-by-step explanation:
Since we are informed that Leslie tuned a guitar with 6 strings today and that she then tuned a piano with 37 times as many strings.
This simply means that we have to multiply 37 by 6 strings to get the value of the strings of the piano that she tuned. This will be:
= 6 × 37
= 222 strings.
Leslie tuned 222 strings.
Therefore, the piano has 222 strings, because 37×6=222.
