Answer:
The domain of the function is defined as the possible x values that can be used in this function
So this problem would be written as this(:
so you start with 331 students together, but then you lose 7 who travel in the cars.
331-7=324
then it would be 324 divided by the 6 buses. that would look like this
324/6
that equals 54.
so in conclusion the answer is 54 students went into each bus:) hope that helps you!
The equation of the hyperbola with directrices at x = ±2 and foci at (5, 0) and (−5, 0) is
<h3>How to determine the equation of the hyperbola?</h3>
The given parameters are:
- Directrices at x = ±2
- Foci at (5, 0) and (−5, 0)
The foci of a hyperbola are represented as:
Foci = (k ± c, h)
The center is:
Center = (h,k)
And the directrix is:
Directrix, x = h ± a²/c
By comparison, we have:
k ± c = ±5
h = 0
h ± a²/c = ±2
Substitute h = 0 in h ± a²/c = ±2
0 ± a²/c = ±2
This gives
a²/c = 2
Multiply both sides by c
a² = 2c
k ± c = ±5 means that:
k ± c = 0 ± 5
By comparison, we have:
k = 0 and c = 5
Substitute c = 5 in a² = 2c
a² = 2 * 5
a² = 10
Next, we calculate b using:
b² = c² - a²
This gives
b² = 5² - 10
Evaluate
b² = 15
The hyperbola is represented as:
So, we have:
Evaluate
Hence, the equation of the hyperbola is

Answer:
(3,2)
Step-by-step explanation:
start off by plugging in 2x - 4 for every y in an equation then solve for x after plug in the number u got for x in an equation then solve for y afterwards an ordered pair is always x value first y value next
