Emily took 39 minutes to bike the biking section of a race. it then took her 9 minutes per mile to run the running section of the race. she represented this with the equation t= 39+9m, where t represents the total time she was racing in minutes and m represents the number of miles she ran in the running section. what is the slope and the y-intercept of this data

Slope=9, y-intercept= 39

Step-by-step explanation:

The equation is already in y=mx+b form, where m is the slope and b is the y-intercept

(rearrange positions of 9m and 39 to get t=9m + 39)

So, the slope is 9 and the y-intercept is 39

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
