Answer:
one solution
Step-by-step explanation:
it has one solution because the slopes of the two equations(1x & 2x) are different, which means the lines of the two equations are not parallel, they have an intersection point(also means one solution).
39/40 as a decimal is 0.975
Answer:
Coordinates of G = 
Step-by-step explanation:
Given: Three vertices of parallelogram DEFG are D(-4,-2), E(-3,1) and F(3, 3).
To find: coordinates of G
Solution:
Midpoints of a side joining points
are given by 
Diagonals of a parallelogram bisect each other.
So,
Midpoint of DF = Midpoint of EG
Midpoint of DF = 
Midpoint of EG = 
Let coordinates of G be 
Therefore,

So,
Coordinates of G = 
Your length is 2 to 8.
Your width is 3 to 7.
Length is 6
Width is 4.
6*4=24.
The rectangle's area is 24
4% of 200,000 is 8,000 multiplied by 30 years would be 240,000 dollars
