Answer:11x
Step-by-step explanation:
Answer:
Step-by-step explanation:
Plug in the given value of y, -2, and solve for x:
-2 + 2 = -3x + 4 and
0 = -3x + 4 and
-4 = -3x so
x = 4/3
Basiclaly, when will total distance equal distance they are apart
distance apart=280
distance=speed times time
assuming they travel sasme amount of time
time=t
distance=speed times time
d1=95 times t
d2=105 times t
total distance=d1+d2
280=d1+d2
280=95t+105t
280=200t
divide both sides by 200
1.4=t
answer is 1.4 hours or 84 mins
Allow me to review before I start. Inconsistent means there's no solution to the system of simultaneous equations, i.e. parallel lines. Consistent means there's at least one solution. Independent and dependent apply to consistent systems. The former means exactly one solution (two lines in different directions which meet). Dependent means an infinite number of solution; the two lines are really the same line.
1. We have two different slopes, lines in two different directions, so they'll meet in exactly one place. That system is consistent and independent, the usual case.
2. We can write the first one y-3x= -2 and the second y-3x=+2. These are parallel lines that are different, so no solution: inconsistent.
3. The first equation is x+2y=4, same as the second. An infinite number of solutions. Consistent and dependent.
