First, we should rearrange the first equation to set it equal to y:
-x + 2y = 6
2y = 6 + x
y = 3 + 0.5x
Now, we can plug this into the second equation for y and solve for x:
6y = x + 18
6(3 + 0.5x) = x + 18
18 + 3x = x + 18
3x = x
2x = 0
x = 0
The x-value of the solution is 0.
Answer:
He has written about 100 times as many words.
Step-by-step explanation:
In order to find this, we first need to find the number that he has written this month. In order to do so, we need to subtract the previous month from the current total.
12,580 - 125 = 12,455
Now that we have that number, we can divide it by the previous month to see how many times more words he wrote in the second month.
12,455/125 = 99.64 times more, or rounded, about 100 times more.
Answer:
In bold below.
Step-by-step explanation:
Find derivative which gives the velocity:
V = h' = -32t + 28
At maxm height V = 0 so
-32t + 28 = 0
Time to reach maxm height t = -28/-32 = 0.875 seconds.
So maxm height
= -16(0.875)^2 + 28*0.875 + 8
= 20.25 ft.
Answer:(c). No. Both variables must be quantativite
Step-by-step explanation:
Both variables must be quantitative because we can calculate Pearson correlation if they are both quantitative
