<u>Answer:</u>
<u>Distance:</u> 6x + 15.5y > 55.5
<u>Time:</u> x + y > 4.5
<u>Step-by-step explanation:</u>
We are given that Martha is training for a duathlon and she covered a total distance of over 55.5 miles in more than than 4.5 hours of training.
Also, she runs at a speed of 6 mph and bikes at a rate of 15.5 mph.
We are to write inequalities representing the distance she traveled and the total time she spent training.
<u>Distance:</u> 6x + 15.5y > 55.5
(formula for distance = speed x time so speeds for running and biking are multiplied by their number of hours)
<u>Time:</u> x + y > 4.5
(she trained for more than 4.5 hours, x hours for running and y hours for biking.
Answer:
Parent Function: y = x^2
Vertex: (1,3)
Axis of Symmetry: x = 1
Y-Intercept(s): (0,1)
X-Intercept(s): (1−√62,0),(1+√62,0)
Step-by-step explanation:
hope this helps! =)
It’s D. 4 is the one next to X because that’s what is changing and -3 is the y intercept which comes after X
