The function h(t) = 150 – 9t represents the height of a ball dropped from 150 feet after t seconds. What will the height of the
Alekssandra [29.7K]
After 1.4 seconds, t = 1.4.
h(t) = 150 - 9(1.4)
Multiply 9 by 1.4 to get 12.6. 
h(t) = 150 - 12.6 
Subtract 12.6 from 150 to get 137.4. 
h(t) = 137.4.
The height of the ball would be 137.4 after 1.4 seconds. 
Hope this helps!

8x-11+5x+2x+6=180 what is the measurement for x.
Verizon [17]

I assume you're looking for the value of x?

Combine like terms: 8x+5x+2x-11+6=180 -> 15x-5=180

Add 5 to both sides: 15x=185

Divide both sides by 15: x=12 1/3

So x is 12 1/3 or 37/3

Hope this helped!

arlik [135]

Answer:

\boxed{\bold{\frac{x+5}{5x-3}}}

Explanation:

[ Step One ] Factor \bold{x^2+4x-5}

\bold{x\left(x-1\right)+5\left(x-1\right)}

[ Step Two ] Rewrite Equation

\bold{\frac{\left(x-1\right)\left(x+5\right)}{5x^2-8x+3}}

[ Step Three ] Factor \bold{5x^2-8x+3}

\bold{\left(x-1\right)\left(x+5\right)}

[ Step Four ] Rewrite Equation

\bold{\frac{\left(x-1\right)\left(x+5\right)}{\left(5x-3\right)\left(x-1\right)}}

[ Step Five ] Cancel Out Common Factor \bold{x-1}

\bold{\frac{x+5}{5x-3}}

\boxed{\bold{Mordancy}}
