Answer:
155
Step-by-step explanation:
first add 72 and 83 = 155. Then use 180-155=25. then subtract 25 from 180.
D i’m pretty sure; -5 x 2 is -10 x 3 = 30
An arithmetic sequence would have a common difference between successive terms, not the case here.
A geometric sequence has a common ratio; let's check:



That's a common ratio of 3 so as far as we can tell a geometric sequence.
Answer: geometric
Answer:
Hello,
First equation is false
Second equation is true
Step-by-step explanation:
1)
(4,-3) is a point of the line y=4x-19 since
-3=?4*4-19
-3=-3
2)
(4,-3) is not a point of the line y=1/4x-2 since
-3=? 1/4*4-2
-3=? 1-2
-3≠-1
I have written that because it is difficult for me to understand
"the negative reciprocal of the slope of the first"
the negative reciprocal of 4 should be -1/4.
Equation y=1/4x-2 is false.
