Answer:
undefined
Step-by-step explanation:
Sin(x) = 0 where x = 0
Cos(x) = 1 where x = 0
Cot(0) is undefined
Rearrange the equation so the left side starts out as y =
5x + 3y = -4
3y = -5x - 4
y = (-5/3)x - (4/3)
the slope is in front of the x and the y-intercept iis the other number
slope is -5/3
y-interxept = -4/3
Divide 15 by 3 then multiply that number by 5.
15/3=5
5 x 5 = 25 apple pies.
think of it like this:
How many small groups of [3 blueberry pies] was in the group of 15. the answer is 5. so if the baker makes 5 for every three, and there are 5 threes, then there will be 25 apple pies. because 5 times 5 is 25.
Answer:

Step-by-step explanation:
Answer:
63 kilometers per hour for train A and 83 kilometers for train B
Step-by-step explanation:
Same beginning
- Train A: 3 hours to North
- Train B: 2 hours and 15 minutes to South
but train B <em>2</em><em>0</em><em> </em><em>kilometers </em><em>per hour </em><em>faster</em>
15 minutes from 20 kilometers per hours are 5 kilometers
So, train B is 45 kilometers travel more far than train B.
= 360 kilometers - 45 kilometers
= 315 kilometers ÷ 5 hours
= 63 kilometers per hours
Hope it's right><
