So, the correct choice is G.
If p is an integer, which of the following is the solution set for 2| p | = 16?
{0, 8}
{ 8, 0}
{ 8, 8}
{ 8, 0, 8}
By definition of absolute value, p could be 8 or
So, the correct choice is C.
Graph each system and determine how many solutions it has. If it has one solution, name it.
y = 5
3x + y = 1
To graph the system, write both equations in slope-intercept form.
y = 5
y = 3x + 1
The graph appears to intersect at the point (2, 5). You can check this by substituting 2 for x and 5 for y.
The solution is (2, 5).
