Step-by-step explanation:
let's think about it logically :
|x| can only be positive, from 0 to +infinity.
but the second part "- 4" will bring the result for small x values into the negative realm.
x = 0 gives us f(x) = -4.
x = 4 gives us f(x) = 0
x = -4 gives us f(x) = 0
so, if is the 3rd graph (bottom left).
Answer:
10 < x < 20
Step-by-step explanation:
the sum of any two sides of a triangle has to be greater than the 3rd side, so the maximum value of the third side in this instance is 19.9999999 because 10 + 10 = 20
Answer: 3 1/3 miles
Step-by-step explanation:
Answer:
The final position of the ball is on the 16 yard line.
Step-by-step explanation:
The final position of the ball after the fourth play is given by the initial position, in this case the 27-yard line, followed by a succession of sums and subtractions depending on the outcome of each play. For gains we sum and for losses we subtract. So we have:
final position = 27 + 6 - 12 + 2 -7
final position = 27 - 11
final position = 16
The final position of the ball is on the 16 yard line.
