Answer:
1.) It has one solution (–5, 5).
if you click on the photo it will show you how to get the answer. I hope this helps you.
1.If the slopes of each equation are the same, they are parallel. If the slopes are the opposite reciprocal of each other, they are perpendicular.
2. The equations are parallel, here’s my work:
Answer:
a. 2.2 b. 5.1 if rounded c. 9.3 if rounded
Lets list the differences in the above list : these are 2 5 11 23 47:
call this list a
This last list has difference 3 6 12 24 (list b) so next number in this list is 48 and next number in list a is 47+48 = 95
In the original sequence therefore the next number is 89 + 95 = 184
so the list a and b are 2 5 11 23 47 95 List a
3 6 12 24 48 List b
The next number in list b is 96 and the next in list a is 96 + 95 = 191
so next number in sequence in question = 184 + 191 = 375
Next number in list b is 192 and next in list a = 191 + 192 = 383
So last number in sequence = 375 + 383 = 758
Next 3 numbers are 184, 383 and 758 answer
Sorry but I cant figure out the explicit rule at moment. I'll try and come back with it.
