Answer:
x = -9/22 or -0.409 to the nearest thousandth.
Step-by-step explanation:
Cross multiplying we get:
(3x + 1)(x - 5) = (3x + 2)(x + 2)
3x^2 - 14x - 5 = 3x^2 +8x + 4
3x^2 - 3x^2 - 14x - 8x = 4 + 5
-22x = 9
x = -9/22
Answer:
<h2>4x-5y+32=0 is the right answer.</h2>
The ball will be at height 19 feet first at 0.7 sec and then at 1.42 sec.
<u>Explanation:</u>
We need to find the time at which the ball will be at height 19 feet.
Equation:
h = 3 + 34t - 16t²
19 = 3 + 34t - 16t²
16 = -16t² + 34t
-16t² + 34t - 16 = 0
On solving the equation, we get
t1 = 0.7 s and t2 = 1.42s
Therefore, the ball will be at height 19 feet first at 0.7 sec and then at 1.42 sec.
