Answer:
a) The arithmetic sequence with common difference 2 that has 8 as the first term.
b) The arithmetic sequence of common difference -5 and first term 15.
Step-by-step explanation:
Let's use for example the arithmetic sequence with common difference 2 that has 8 as the first term. Then the first two terms of this sequence are:
8, and (8+2) = 10 Therefore the second term is 10.
Another arithmetic sequence of common difference -5 and first term 15. The firs two terms of this sequence are:
15, and (15 - 5) = 10. Therefore again a 10 as second term.
Answer:
x = 2/3
Step-by-step explanation:
Do butterfly multiplication and solve. the 3's cancel and divide 4 by 6.
You can not simplify 7/10 because 7 os only on 1 and 7s times table.
Answer:
the triangle A is translation to the triangle B.
Step-by-step explanation:
The ratio of x-coordinates is
4
/7 = 1.75 , so the scale factor of the dilation that maps (4,6) onto (7,9) is 1.75.
So, translation: (x,y) ↦ (x−2,y−1)
