Answer:
4x + y = 43
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Given
y = 43 - 4x ( add 4x to both sides )
4x + y = 43 ← in standard form
Answer:
x = 4
Step-by-step explanation:
4x-5 = 2x+3
subtract 2 x from each side and add 5 to each side
2x = 8
x = 4

The ratio of the geometric sequence 40
is 2.
Given that geometric sequence is 40*
and we have to find the common ratio of all the terms.
Geometric sequence is a sequence in which all the terms have a common ratio.
Nth termof a GP is a
in which a is first term and r is common ratio.
Geometric sequence=40*
We have to first find the first term, second term and third term of a geometric progression.
First term=40*
=40*
=40*1
=40
Second term=40*
=40*
=40*2
=80
Third term=40*
=40*
=40*4
=160
Ratio of first two terms=80/40=2
Ratio of next two terms=160/80=2
Hence the common ratio of geometric sequence is 2.

Hey there! I'm happy to help!
Don't let this negative on the outside freak you out. It just means -1. We want to multiply everything on the inside of the parentheses by -1 to simplify.
-1(5.8a)=-5.8a
-1(4.2b)=-4.2b
So, our final expression is -5.8a-4.2b.
Have a wonderful day! :D
