Answer:
The correct answer is NO.
Step-by-step explanation:
John is graphing two lines with equations say ax + by + c = 0 and dx + ey +f =0 on his graphing calculator.
For John to get a unique solution the coefficients should follow the following condition 
. So when he plots the lines he get an intersecting pair of lines.
For John to get no solution the coefficients should follow the following condition 
. When we plot in this case we get two parallel lines.
For John to get an infinite many solution the coefficients should follow the following condition 
. And when we plot the lines in this case we get one line superimposed on the other.
Since after graphing, John sees only one line, the lines must have superimposed on one another giving John an infinite number of solutions.

Answer:
The ratio of the areas of the smaller rectangle to the larger rectangle is 
Step-by-step explanation:
we know that
if two figures are similar, then the ratio of its areas is equal to the scale factor squared
Let
z-----> the scale factor
x-----> the area of the smaller rectangle
y----> the area of the larger rectangle
so
substitute the values
simplify
That means, the area of the larger rectangle is 9 times the area of the smaller rectangle
------> the scale factor
That means, the dimensions of the larger rectangle is 3 times the dimensions of the smaller rectangle
18a:16 18b:32 % means out of 100
If a ratio of skiers and snumboarders is 1:2, and if there are 1250 snowboarders more than skiers, it means that is that there 2500 snowboarders and 1250 skiers.
How to check it? 2500 is 1250 more than 1250 and the ratio is still 1:2 (there are two times more snowboarders than skiers). Both conditions are fulfiled, so it's correct.
