Answer:
Since the question is indicating to use a graphing calculator, we can assume that we would be required to graph both of the equations.
Red = 
Blue = 
By graphing those equations, we can determine the solution(s)
The points where the graphs intersect would be your coordinates to derive your solution
Red = (1.864, 1.966)
Blue = (-0.427, 1.254)
The solutions would be the x-value of the ordered pair, in this case,
x = 1.864 AND x = -0.427
Answer:
= 1
Step-by-step explanation:
The n th term of an arithmetic progression is
= a + (n - 1)d
where a is the first term and d the common difference
use the 9 th term and 7 th term to find a and d
= a + 8d =
→ (1)
= a + 6d =
→ (2)
Subtract (2) from (1) term by term
2d =
⇒ d = 
Substitute this value into (2) and solve for a
a +
= 
a =
-
= 
Hence
=
+
= 1
