Answer:

x = -1, y = 1

Step-by-step explanation:

2x-y=-3 // y = 2x + 3 (eqn 1)

3x+y=-2 (eqn 2)

sub 1 into 2

3x + 2x + 3 = -2

5x = -5

x = -1

sub x = -1 into eqn 1

y = -2+3

y = 1

How many terms are in the arithmetic sequence 9, 2, −5, . . . , −187?

Fantom [35]

9, 2, -5... so is going down by 7 each time, meaning the "common difference" is -7.

$\bf n^{th}\textit{ term of an arithmetic sequence}\\\\
a_n=a_1+(n-1)d\qquad 
\begin{cases}
n=n^{th}\ term\\
a_1=\textit{first term's value}\\
d=\textit{common difference}\\
----------\\
a_1=9\\
d=-7\\
a_n=-187
\end{cases}
\\\\\\
-187=9+(n-1)(-7)\implies -187=9-7n+7
\\\\\\
7n=9+7+187\implies 7n=203\implies n=\cfrac{203}{7}\implies \boxed{n=29}$
