It will take her 51.4 minutes.
Explanation:
You would do 12/7 and then multiply that answer by 30.
If you have a slope of -4 then it would be -4/1 because rise/run. If it were -4/-1 then the slope would be 4.
The request is to find the intersection of the two sets. By definition, the intersection of two sets is another set, composed by all the elements appearing in both sets.
In other words, 
is the set of all elements that P and Q have in common.
P contains all the numbers from 0 to 9, V contains all the odd numbers between 1 and 19. So, their intersection will be the odd numbers between 0 and 9, i.e.
Hello!
As you can see, the angles we are given make up a 90 degree angle. We have the equation below.
4x=90
To solve we just divide both sides by 4.
90/4=22.5
x=22.5
I hope this helps!
F(4)= -4-8=-12
F(-2)=-(-2)-8=2-8= -6
F(2)= -2-8=-10
F(0)=0-8=-8
F(-3)= -(-3)-8=3-8=5
