Barry records the height of a balloon from the ground from 2 seconds after he left it go for 12 seconds. the function h(t)=|t+2|-1 models the height h over t seconds. a: What was the balloon’s height from the ground when Barry started recording the height ?

b: what was the balloons height from the ground when barry stopped recording the height

c: predict how high the balloon was when he let it go, even though he did not record the height.

d: is an absolute value function needed to model the height of the balloon from the ground?

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
