Answer:

Option B - $y=5x+40$ and $y=3x+60$

Step-by-step explanation:

Given : The Thrill amusement park charges an entry fee of $40 and an additional $5 per ride, x. The Splash water park charges an entry fee of $60 and an additional $3 per ride, x.

To find : Which system of equations could be used to determine the solution where the cost per ride of the two amusement parks, y, is the same?

Solution :

Let x be the number of rides and

y be the cost per ride.

According to question,

The Thrill amusement park charges an entry fee of $40 and an additional $5 per ride.

The equation form is $y=40+5x$

The Splash water park charges an entry fee of $60 and an additional $3 per ride.

The equation form is $y=60+3x$

Therefore, The required system of equations form are

$y=5x+40$ and $y=3x+60$

So,Option B is correct.

Drupady [299]

Answer:

Time taken by the submarine to reach the cave is 10 seconds.

Step-by-step explanation:

We are given that,

The elevation of the underwater cave = -120 feet.

The rate at which the submarine descends to the cave = -12 feet per second

Thus, we have,

The time taken by the submarine to reach the cave = $\frac{-120}{-12}$ = 10 seconds.

Hence, the time taken by the submarine to reach the cave is 10 seconds.

Could someone pls help me out ???

professor190 [17]

Answer:

Option C.

Step-by-step explanation:

$\sf\:x^{2}-3x+7=0$

Use the biquadratic formula.

$\sf\:\x=\frac{-\left(-3\right)(+/-)\sqrt{\left(-3\right)^{2}-4\times 7}}{2}$

$\sf\:x=\frac{-\left(-3\right)(+/-)\sqrt{9-4\times 7}}{2}$

$\sf\:x=\frac{-\left(-3\right)(+/-)\sqrt{9-28}}{2}$

$\sf\:x=\frac{-\left(-3\right)(+/-)\sqrt{-19}}{2}$

$\sf\:x=\frac{3(+/-)\sqrt{19}}{2}$

Positive sign:

$\boxed{\sf\:x=\frac{3+\sqrt{19}}{2}}$

Negative sign:

$\boxed{\sf\:x=\frac{3-\sqrt{19}}{2}}$

Hope it helps ⚜
