First you need to form a worthy equation using slope-intercept (y=mx+b). Do that by counting the slope and finding the y-intercept. Then you have to choose between < or > to make it more accurate. In order to do so, you would have to pick a point with a point x and y and see wether or not I’m the equation is true when you put it in the blanks. If it’s true then you would shade whichever region the point is. If it’s false then shade the opposite region.
Good luck!!!!!!! :)

Answer:
A) a_n = 5n + 2
B) a_n = (2^(n + 1)) - 1
Step-by-step explanation:
A) The sequence is given as;
{7,12,17,22,27,...}
The differences are:
5,5,5,5.
This is an arithmetic sequence following the formula;
a_n = a_1 + (n - 1)d
d is 5
Thus;
a_n = a_1 + (n - 1)5
Now, a_1 = 7. Thus;
a_n = 7 + 5n - 5
a_n = 5n + 2
B) The sequence is given as;
{ 3,7,15,31,63,...}
Now, let's write out the differences of this sequence:
Differences are:
4, 8, 16, 32
This shows that it is a geometric sequence with a common ratio of 2.
In the given sequence, a_1 = 3 and a_2 = 7 and a_3 = 15
Thus, a_2 = 2a_1 + 1
Also, a_(2 + 1) = 2a_2 + 1
Combining both equations, we can deduce that: a_(n + 1) = 2a_n + 1
Thus; a_n can be expressed as:
a_n = (2^(n + 1)) - 1
Answer:
15771 > - 7
Step-by-step explanation:
Comparing the elevation of the two points ;
Point with elevation of 15771 is positive meaning it occurs above sea level and this higher than the point with an elevation of - 7 which is occurring below sea level
Hence, to compare both elevations :
Montblanc has higher elevation than Rhone river delta
Montblanc elevation > Rhone river delta
15771 > - 7
Answer:
-i^5=-i
Step-by-step explanation:
rewrite the equation ;
i^4=1
I^4 *-i = 1*-i=-i
Answer:
There should be a number of 14 students in each row
Step-by-step explanation:
Find the factors of 196 then find the Greatest factor pairs which give you the numbers of 14 and 14. Now you have your answer of 14 rows and 14 columns.
