Bought for $20,000-$16000( present rate)=$4000 is the difference
$2000 is 10% of 20000 times 2 is $4000=answer
5a - (-2a) + 9
When you subtract a negative number, you can replace the 'double negative' with a positive, or addition. So, instead of subtracting -2a, you can add 2a.
5a + 2a + 9 Combine like-terms
7a + 9
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.

Yes
Step-by-step explanation:
Dan used 2 and 6, and after 3 and 9. If you multiply 2×1.5 = 3, and 6×1.5 = 9, so the ratio is the same and is equal to 1.5
