Answer:
B. Infinitely Many
Step-by-step explanation:
Step 1: Distribute
5x + 48 + 7x = 12x + 48
Step 2: Combine like terms
12x + 148 = 12x + 48
If the 2 lines are the same, which they are, they are the same lines. That means there are an infinite amount of solutions. If they had the same slope but different y-intercepts, there would be no solutions because the lines are parallel. Any other pair of equations would have 1 solution.
Answer: x = -7
Step-by-step explanation:
x = -7 will be a vertical line passing through all y values, and perpendicular to y = 5
The attached graph shows the lines and the point.
Let x be the number of miles EXCLUDING the first
Amount of money paid (excluding the first : $(0.1).x
Total money paid (INCLUDING the 1st mile):
0.90 + (0.1)x = $3.2
0.1.x = 3.2 -0.90
0.1.x = 2.3
x = 2.3/0.1 = 23 miles
Now we have to add the 1st mile, then the total of miles = 23+1 = 24 Miles
the other point at x=-1 is (-1,0)
this fails the vertical line test so it is a relation not a function
