Which is not a function
An ordered pair is represented as:
However, for the ordered pair to be a function; all the x values must be unique (i.e. not repeated)
<em>From options (a) to (d), option (b) has -6 repeated twice. Hence, it is not a function.</em>
Answer:
D) infinitely many solutions
Step-by-step explanation:
5 ( x-3 ) - 3x = 8x - 15 - 6x
5x - 3x - 15 = 8x - 6x - 15
2x - 15 = 2x - 15
2x = 2x
Since, equations of both lines are same. Therefore, there are infinitely many solutions.
Brazil population: 1.907×
Mexico population 1.123×
To find how much more the population was in Brazil than in mexico, you would subtract the Brazil population to Mexico's population:
The 's would not cancel out because they are representing further decimal places that aren't written, so you would subtract 1.907 and 1.123.
1.907 - 1.123= 0.784
Brazil's population is 0.784× larger than Mexico.
to calculate y intercept we need to put x = 0 in equation.
3x + 2y = 14
3×0 + 2y = 14
y = 14/2 = 7
so point is
(0, 7)
option B
