Answer:
(2,-3)
x=2 y=-3
Step-by-step explanation:
2x+y=1 y=1-2x
3x+2y=0
3x+2(1-2x)=0
3x+2-4x=0
-x+2=0
-x=-2
x=2
2x+y=1
2(2)+y=1
4+y=1
y=-3
If the <em>n</em>-th term of the sequence is given by <em>n</em> ² - 2, then the 5th term is obtained by simply replacing <em>n</em> with 5 :
5² - 2 = 25 - 2 = 23
Answer:3(2m-7p)
Step-by-step explanation:
you just divide each number by a common factor
Answer:
j = - 20
Step-by-step explanation:
-2 + j = -22
-2 + 2 + j = -22 + 2
j = - 20
Recall
or, $\csc^2\theta-\cot^2\theta=1 \implies (\csc\theta+\cot\theta)(\csc\theta-\cot\theta)=1$
Now, $\cot \theta - \csc \theta = P$
$\implies (-P)(\csc\theta+\cot\theta)=1$
or $(\csc\theta+\cot\theta)=-\frac{1}{P}$
