Easy, make it easy to do mentally than add the remaining
The two lines will intersect at the point (7, 7)
We have got an geometric progression.
We use to find any term of a geometric sequence, this equation:
an=a₁ * r^(n-1)
a₁= is the first term.
r=is the common ratio.
n=numbers of the term to find.
r=an / an-1
In this case:
r=a₂/a₁=(-4.8) / 9.6=-0.5
a₁=9.6
an=9.6*(-0.5)^(n-1)
Answer:
4x + y = -1
Step-by-step explanation:
To get both variable terms on the same side, you can add 4x. Its coefficient will then be positive, and all coefficients are mutually prime, so you're done.
4x +y = 4x -4x -1 . . . 4x added to both sides
4x + y = -1 . . . . . . . simplify
