Answer:
one solution
Step-by-step explanation:
A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line). This article reviews all three cases. One solution. A system of linear equations has one solution when the graphs intersect at a point.
Answer:
- sign = negative, degree = 5
Step-by-step explanation:
<u>The graph has negative leading coefficient as </u>
It is of the odd degree, and the degree is most probably 5
The answer is <u>C: Income tax</u>
The distance is the same. So the two conditions (driving there and driving back) can be equated.
There
t = 3 hours
d = d
r = 54 mph
Back
t = ?
d = d
r = 60 mph
Basic Formula
d = r * t
Solution
54 * 3 = 60 * t Combine the left side
162 = 60 * t Divide by 60 on both sides
162 / 60 = t Combine
2.7 hours = time coming back.
0.7 hours = 60 * 0.7 = 42 which is in minutes.
2 hours and 42 minutes. Answer
