Answer:
A balloon rose 32 feet in the air then it fell down to the ground
Step-by-step explanation:
Y=-5x+8 I guess this is the y-intercept way
Answer:
D=24
Step-by-step explanation:
y inversely as x
x=k/y
By cross multiplication
k=xy
k=12*6
k=72
finding y
72=3y
y=24
Answer:
<em>( About ) 1.77 seconds; Option B</em>
Step-by-step explanation:
We are given the equation h ( t ) = - 16t^2 + 50, so in order to determine the time let us determine the x - intercept for y ⇒ 0;
- 16t^2 + 50 = 0,
- 16t^2 = - 50,
t^2 = 25 / 8,
Thus t ⇒ √ ( 25 / 8 ), and t ⇒ - √ ( 25 / 8 ),
t ⇒ ( 5√2 )/ 4, and - ( 5√2 )/ 4,
But time is represented only by a positive value, thus
t ⇒ ( 5√2 )/ 4 = 1.767766953......., ( About ) 1.77 seconds

Answer:
Let's solve!
Step-by-step explanation:
2x + 6x - 9 = 0
\____/
8x - 9 = 0
+ 9 + 9
<u>8x </u> = <u>9</u>
8 8
x = 9/8 --or-- 
x = 1.125
I hope this helps!
