The equation is not linear. It is a parabola.
Hope this helped☺☺
1 day = 24 hours:
58 days x 24 hours per day = 1,392 hours
1 hour = 60 minutes:
30 minutes / 60 minutes per hour = 0.5 hours.
1392 + 15 + 0.5 = 1,407.5 total hours.
Answer:
A
Step-by-step explanation:
3x-y=-10
y=3x+10
so the equation “x+2y=6” is “x+2(3x+10)=6” so we have:
x+6x+20=6
7x=6-20
7x=-14
x=-14/7=-2
to get y we can replace x with its value “-2” in the equation”y=3x+10” so we have:
y=3(-2)+10=-6+10=4
Let the time that you caught up with your friend be t, then
8.5 - 3.4t = 8 - 3t
3.4t - 3t = 8.5 - 8
0.4t = 0.5
t = 0.5/0.4 = 1.25
therefore, you will catch up with your friend after 1.25 hours.
b.) time it will take you to cross the finnish line = 8.5/3.4 = 2.5 hours
After 2.5 hours, distance covered by your friend = 3 x 2.5 = 7.5 miles
Therefore, when you cross the finish line, you are 8 - 7.5 = 0.5 miles ahead of your friend.
