Answer:
Option C is correct.
System of equation which will produce infinitely many solutions:
3x - y = 14
-9x +3y = -42
Step-by-step explanation:
From the options
Only equation which is infinitely many solutions is
3x - y = 14 ......[1]
-9x +3y = -42 ......[2]
For infinitely many solutions, we are looking for linearly dependent equations, which means one equation is an exact multiple or sub-multiple of the other.
Multiply [1] by -3 we get
or
-9x + 3y = -42 which is same equation as [2]
therefore. by definition of infinitely many solution,
equation 2 is -3 times(or multiple) of equation 1
Answer:
school day
Step-by-step explanation:
When drawing a chart or a graph:
- x-axis: Independent variable
- y-axis: Dependent variable
The two given variables are:
- number of students who wear blue shirts
- days of the week
Therefore, in this scenario the <u>independent variable</u> is the <u>school day</u> and the <u>dependent variable</u> is the <u>number of students</u> since the former effects the latter.
So the data on the horizontal axis (x-axis) is: school day
