Two students set off traveling due north from their separate houses to go on a long distance bike ride. alex lives 20 miles north of jenna, and travels at 11 miles per hour. jenna travels at 13 miles per hour. select all of the equations that can be used to represent this situation, where x represents the number of hours and y represents the total distance traveled.

a. y=11x
b. y=11x-20
c. y=11x+20
d. y=13x+20
e. y=13x

Answer : The correct options are:

c. y = 11x + 20

e. y = 13x

Step-by-step explanation :

As we are given that distance between Alex and Jenna is, 20 miles.

Speed of Alex = 11 miles/hour

Speed of Jenna = 13 miles/hour

Total distance = y miles

Time = x hour

Distance traveled by Alex = (y-20) miles

Distance traveled by Jenna = y miles

As per question condition, there are two equations.

As we know that,

So,

    ............(1)

    ............(2)

Thus, the equations that can be used to represent this situation are, and

a. the residual plot for model 1 has a random pattern and is a good fit for the data.

step-by-step explanation:

a child is 12 years old, and his father is 32 years older. in how many years will the age of the father be 2 times the age of the child?

******************

this needs to be the answer format, or else your answer is incomplete.

if the number of years is x, then the equation is

in __ years
