The equation that be used to determine possible locations of the origin of the sound [tex]\dfrac{ x^2}{680,625} - \dfrac{ y^2}{3,319,375 }= 1[/tex]
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
A pair of listening posts is 4,000 ft apart.
They both pick up a sound, but one listening post records the sound 1.5 seconds after the other listening post.
Assume sound travels at 1,100 ft/s.
The equation would become

Solve the equation:
7m+19/2=13
Answer:
1
Step-by-step explanation:
7m+19/2=13
7m +19 = 13 x 2
7m = 26 - 19
m = 7/7 = 1
Another way :
7m+19/2=13
7m = 26/2 - 19/2
7m = 7
m = 7/7 = 1
Both ways r correct !!
I hope im right!!

What is the value of x?
Answer:
B
Step-by-step explanation:
Since UV is a tangent then ∠ WUV = 90°
WZ = WU = x - 1 ( both radii of the circle ) , then
WV = x - 1 + 2 = x + 1
Using Pythagoras' identity in the right triangle
WU² + UV² = WV² , that is
(x - 1)² + (2x - 4)² = (x + 1)² ← expand factors using FOIL
x² - 2x + 1 + 4x² - 16x + 16 = x² + 2x + 1
5x² - 18x + 17 = x² + 2x + 1 ← subtract x² + 2x + 1 from both sides
4x² - 20x + 16 = 0 ← divide through by 4
x² - 5x + 4 = 0
(x - 1)(x - 4) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
x - 4 = 0 ⇒ x = 4
But x ≠ 1 as radius x - 1 = 0
Thus x = 4 → B
