Answer:
difference = 3, first term = 4
Step-by-step explanation:
given, a2 = 7
a9 = 28
wkt, a2 = a + d = 7
<u>a9 = a + 8d</u><u> </u><u>=</u><u> </u><u>28</u>
- 7d = - 21
therefore d = 3
and wkt, d = a2 - a
a = 7 - 3 = 4

For this case we must express the following expression algebraically:
<em>"The quotient of b and 2 minus 4 is at least 26"</em>
So we have to:
The quotient of b and 2 minus 4, is represented as:![\frac {b} {2-4}](https://tex.z-dn.net/?f=%5Cfrac%20%7Bb%7D%20%7B2-4%7D)
We have different signs subtracted and the sign of the major is placed:
![\frac {b} {- 2}](https://tex.z-dn.net/?f=%5Cfrac%20%7Bb%7D%20%7B-%202%7D)
Thus, the expression is written as:
![\frac {b} {2-4} \geq26\\\frac {b} {- 2} \geq26\\- \frac {b} {2} \geq26](https://tex.z-dn.net/?f=%5Cfrac%20%7Bb%7D%20%7B2-4%7D%20%5Cgeq26%5C%5C%5Cfrac%20%7Bb%7D%20%7B-%202%7D%20%5Cgeq26%5C%5C-%20%5Cfrac%20%7Bb%7D%20%7B2%7D%20%5Cgeq26)
ANswer:
![\frac {b} {2-4} \geq26](https://tex.z-dn.net/?f=%5Cfrac%20%7Bb%7D%20%7B2-4%7D%20%5Cgeq26)
