Answer:
y-3=1/4(x+7)
Step-by-step explanation:
y-y1=m(x-x1)
y-3=1/4(x-(-7))
y-3=1/4(x+7)
Answer: 120 people
Step-by-step explanation: To do this problem, you want to find common denominators. The lowest common denominator is 900. So to get the denominator to 900 from 30, multiply it by 30. 30 x 30=900. Multiply 4 by 30. 4 x 30=120. Another way to do this is to set up a proportion. It would be 4/30=x/900. Cross multiply and solve for x. 3600=30x. X=120.
To find each rate you could write each one as a fraction, in this case when the child runs against the sidewalk it can be expressed as 24/6. Simplify the fraction by dividing numerator and denominator both by 6 and you will get a rate of 4 ft in 1 second. When the child runs with the sidewalk's motion the fraction would be 24/2. Simplify the numerator and denominator by 2 and you will get a rate of 12 ft in 1 second.
