Answer:
x = - 5, - 6
Step-by-step explanation:

Leila runs at 12 miles per hour. Find the number of miles she can travel if she runs for k less than 6 hours
Answer:
72-12k
Step-by-step explanation:
Our information:
Speed=12mph
Distance=x
Time=K less than 6 hours
Using the distance triangle, (Distance over speed and time,) We can use this equation.
TxS=D
12x(6xk)=D
72-12k
The number of miles she can travel if she runs for k less than 6 hours will be 12k-172.
What is the distance?Distance is a measurement of the separation between two things or places. When we talk about distance, we're talking about a physical length or an estimate based on other physics or practical usage factors.
It is given that,
Speed=12mph
Distance=x
Time, t= (K - 6) hours
The distance for the given condition is,
d = v × t
d = 12 (K - 6)
d = 12k - 72 miles
Thus, the number of miles she can travel if she runs for k less than 6 hours will be 12k-172.

can someone tell me how to find the perpendicular line and the parallel line of an equation
EX. y=2x+4
Answer:
Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6. Thus, the equation of the line is y = ½x + 6.
Step-by-step explanation:
