For 11. Not all of the y values (outputs) are consistent with the pattern
Answer:
Step-by-step explanation:
5/6 x 3/10= 15/60=1/4
2/3 x 6/7=12/21=4/7
Answer:
x = 8, -8
When taking an absolute value the sign of a number is ignored. Therefore, both 8 and -8 would come out equalling 8.
Answer:
arithmetic
Step-by-step explanation:
The points fall on a straight line. They won't do that for a geometric sequence.
___
Normally the terms of either sort of sequence are numbered with counting numbers: 1, 2, 3, .... Your x-values are negative, so are obviously not term numbers of a sequence. The differences of x-values are 1, and the differences of y-values are 2.5, so we know the x- and y-values are linearly related. That relationship can be expressed in point-slope form by ...
y = 2.5(x +1) +12.5
which can be simplified to
y = 2.5x +15
__
The arithmetic sequence with first term 17.5 and common difference 2.5 would be described by this same equation.
You only need to look at the y intercepts.
-11 - -7 is -4, but you can't have a negative distance so it's just 4
