The path of the car and the limo are straight lines.
To determine the equation of the lines of the paths, the slopes must be determined.
Let m1 = slope of car
m2 = slope of limo
so,
m1 = (7 + 7)/(5 + 2) = 2
m2 = (-5 -9)/(3+4) = -2
therefore the equations are
car:
2x – y = 2(5) –(7)
2x – y = 3
Limo:
2x + y = 2(3) – 5
2x + y = 1
Solving the intersection of the equations (using a calculator)
x = 1
y = -1
Step-by-step explanation:
80:100=x:20
x=80×20/100=16
Answer:
0.5 = 3
1.5 = 9
4.5 = 27
Step-by-step explanation:
Answer:
i dont speak that good in spanish but i can try
Step-by-step explanation:
Expand
x²+6x-27=-27
add 27 both sides
x²+6x=0
factor
x(x+6)=0
set to zero
x=0
x+6=0
x=-6
x=0 or -6
answer is 0 since -6 is not listed
