  No; the two systems have parallel lines, so cannot have the same solution

Step-by-step explanation:

One system of equations has the line ...

  8x +9y = 48

The other system of equations has the parallel line ...

  8x +9y = 45

Those two lines cannot intersect, so cannot share a solution.

I do not agree with Albert that the two systems have the same solution.

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !

step-by-step explanation:

consider the parallelogram shown in the attached image.

in the parallelogram hijk, the length of hk is given as,

from the properties of parallelogram we know that the opposite sides of a parallelogram are parallel to each other and are equal in measure.

therefore, the length of the side ij must be equal to the length of the side hk and that is .

hence, the expression for the length of ij confirms that hijk is a parallelogram.
