Answer:
an = -9 + 7( n - 1)
Step-by-step explanation:
an = first term + difference (n-1)
First term = 9
Difference = -2 - -9 = -2 + 9 = 7
an = -9 + 7( n - 1)
You can check this by substituting the values in.
a1 = -9 + 7(0) = -9
a2 = -9 + 7(2) = -9 + 7 = -2
a3 = -9 + 7(3) = -9 + 14 = 5
Answer:
About 19 apples (I think)
Step-by-step explanation:
A. 4(a + 1) = 2
= 4a + 4 = 2
= 4a = 2-4 = - 2
= a = - 2/ 4 = - 1/2
B. 3 - 9x = - 6-8x
3 + 6 = - 8x +9x
9 = x
C. 12x - 3 = 14x - 35
- 3 + 35 = 14x - 12x
32 = 2x
32 / 2 = x
16 = x
