Given that the function y=3.5x+2.8 represents the cost y (in dollars) of a taxi ride of x miles, and that <span>you have enough money to travel at most 20 miles.
The domain of a function is the set of possible values of x, given that the maximum number of miles you can travel is 20 miles, the domain of the function is from 0 to 20.
Domain = {x: 0 ≤ x ≤ 20}
The range of a function is the set of the possible values of the function.
For x = 0, y = 3.5(0) + 2.8 = 2.8
For x = 20, y = 3.5(20) + 2.8 = 72.8
Therefore, the range of the function is from $2.8 when no mile was covered and $72.8 when 20 miles was covered.
Therefore, range = {y: 2.8 ≤ y ≤ 72.8}

It's given in the question,
P, Q, V and K are collinear.
VP = 14x + 4
PK = x + 630
VQ = 17x + 6
KQ = 11x + 5
By segment addition postulate,
KQ + VQ + VP = KP
Substitute the values in the expression,
(11x + 5) + (17x + 6) + (14x + 4) = x + 630
(11x + 17x + 14x) + (5 + 6 + 4) = x + 630
42x + 15 = x + 630
42x - x = 630 - 15
41x = 615
x = 
x = 15
Therefore, value of VP = (14x + 4)
= 14(15) + 4
= 214 units

Answer:
3/4
Step-by-step explanation:
7/28 have blue eyes
So 28-7=21
21/28 don't have blue eyes
21/28 simplified=3/4
Depends how strong the bomb is. If the bomb is weak then you would most likely go up 20-30 floors. If the bomb is in the middle go to the stair case and prepare for impact. If the bomb is strong go down 40 floors if possible. If none of this is possible to do and you don't know what to do about it then you must do the following:
Cut all of the wires in the bomb. Get the bomb near of a wall or a window. If it is a window then throw the bomb out of the window. If it is a wall put it as close to the wall as possible gather all your coworkers and run off of the floor.
Hope this helps!
