Steps to solve:
2x - 7 > 3
~Add 7 to both sides
2x > 10
~Divide 2 to both sides
x > 5
Steps to solve:
4 - x <= -4
~Subtract 4 to both sides
-x <= -8
~Divide -1 to both sides
x >= 8
Best of Luck!
3 friends 5 pieces each is 15 total
She had 24 pieces -15= 9 pieces left for herself
For this case we have that by definition the time is given by:
Where the variable "d" represents the distance and "v" represents the speed.
So, first we need to know the total distance:
Then, the time for 75mph is given by:
Answer:
6,4 hours
Step-by-step explanation:
a) Tangent equals sine divided by cosine. Therefore:
tan(-t) = sin(-t) / cos(-t)
b) Using the fact that sin(-t) = -sin(t) and cos(-t) = cos(t):
tan(-t) = -sin(t) / cos(t)
tan(-t) = -tan(t)
c) A function is symmetric about the origin if f(-x) = -f(x) (in other words, if it's an odd function). Therefore, y = tan(t) is symmetric about the origin.
