Answer:
Please check the explanation.
Step-by-step explanation:
As we have to determine a positive angle less than 360 degrees that is conterminal with 540 degrees.
so
540° - 360° = 180°
The resulting angle of 180° is positive, less than 360°, and coterminal with 540°.
If it doesn't matter whether the points are integers or not you can just pick a number for either y or x and solve for the other variable. For example, if you pick 3 to be your x, plug it in and then solve for y. Start out with:
Plug in 3 for x:
. Then,
. Subtract 21 from both sides and then divide by -3 on both sides. You end up with y=-7 so one of your points is (3, -7)
Answer:
8 hours
Step-by-step explanation:
If Jackie wants to burn 2000 calories in one week but only burns 250 calories per hour
then, to solve how many hours you have to divide
2000/250= 8
therefor Jackie has to do aerobics for 8 hours that week to burn 2000 calories
