Answer:
Terry was charged for 4.5 hours of labor.
Step-by-step explanation:
50x + 150 = 375
Where x = hours
50x = 375 - 150
50x = 225
Divide both sides by 50 to isolate x
x = 4.5
The solution is (4,-6) and it is that point because a solution is the intersection point of the two lines.
Answer: 12 pounds
Step-by-step explanation:
0.80x + 3 = $12.60
-3 -3
0.80x = $9.60
9.60 / 0.80 = 12
x = 12 pounds
Answer:
Total Number of lines will be 28
Step-by-step explanation:
We can use combinations to solve this question.
Let the two Collinear points be denoted by A and B and the other other points be denoted by x1,x2,x3,x4, x5 and x6.
Suppose that only A and B are collinear.
The number of lines determined by any two of x1 to x6 are given by 6C2= 15
The number of lines from A or B and x1---x6 is given by 6C1 * 2C1= 12
The number of lines from A to B is 1.
Total Number of lines = 15+ 12+ 1= 28
