Actually, if you notice that two of the lines are parallel, the answer is x=53!
Answer: the second bubble down the first row
Step-by-step explanation:
when you plan the coordinate you need to use 1,2,3,4 to get the simplest answers.
Answer:
sometimes
Step-by-step explanation:
The three altitudes in an acute triangle all lie in the interior of the triangle and intersect inside the triangle. Two of the three altitudes in a right triangle are the legs of the triangle.
{x=-1/3-10/3y
5x+20y=5
5(-1/3-10/3y)+20y=5
solve the equation
.
.
Y=5
substitute the value of y into the equation
x=-1/3-10/3×2
.solve the equation
.
.x=-7
(x,y)=(-7,2)
{3×(-7)+10×2=-1
5x(-7)+28×2=5
simplify
{-1=-1
5=5
the ordered pair is asolution
(X,Y)=(-7,2)
That's all!!!!
Given:
...(i)
For 
.
To find:
The nth term for the given recursive formula.
Solution:
The given recursive formula is of the form of
...(ii)
It is the recursive formula of a GP, where r is common ratio.
On comparing (i) and (ii), we get
Now,
First term: 
Common difference:
nth term of a GP is
Putting a=3 and r=2, we get
Therefore, the equation for the nth term is .
