Solve the absolute value equation.<br>12 + 2x[ = [x - 6]​
Tom [10]

Answer:

x=−18

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

12+2x=x−6

12+2x=x+−6

2x+12=x−6

Step 2: Subtract x from both sides.

2x+12−x=x−6−x

x+12=−6

Step 3: Subtract 12 from both sides.

x+12−12=−6−12

x=−18

Help me with this problem please a and b

(a) Compare your quadratic for h to the general quadratic ax² +bx +c. Perhaps you can see that ...
  a = -16
  b = 128
You use these numbers in the given formula to find the time when the ball is highest.
  t = -b/(2a) = -128/(2(-16)) = 4 . . . . . . the time at which the ball is highest


(b) Evaluate the quadratic to find the height at t=4.
  h = -16(4)² +128(4) +21
  h = -256 +512 +21
  h = 277
The maximum height of the ball is 277 ft.
