Answer:
-3
Step-by-step explanation:
m= 3-(-18)=21 , -3-4=-7
m = 21 / -7 = 3 / -1 = -3

every hour she travels 2 miles, so in 30 minutes she will travel 1 mile, hopefully that can help
Answer:
Step-by-step explanation:
Okay this is an odd question, but what i'm thinking is that
first you have
5x+5
To actually be able to solve we have to move the 5 to the other side.
To do this we subtract it.
Making the equation
5x = -5
Then you need to isolate the variable (X)
So divide 5X by 5, and then divide -5/5
Which leaves you with:
x=-1
Answer:
h = 4cm
Step-by-step explanation:
Diameter = 18cm
Radius = Diameter/2 = 18/2 = 9cm
V = 1/3*pi*r^2*h
We know that the volume is 108pi cm^3. We can just plug in 108pi cm^3 for V and we also know that our Radius (r) is 2.
So,
108 pi = 1/3*pi*9^2*h
108 pi = (81pi*h)/3
multiply 3 from both side
108pi*3 = (81pi*h)/3 *3
324pi = 81pi*h
Now divide the 81pi from both side
324pi/81pi = (81pi*h)/81pi
4 = h
So the height is 4cm
I pretty sure it’s a linear function
