Answer:

Rate of slower bus; 90 km/h

Rate of faster bus; 102 km/b

Step-by-step explanation:

We know that formula do distance is;

Distance = speed/time

We are told that One bus travels 12h slower than the other.

Let speed of slower bus be x.

Thus;

Speed of faster bus = x + 12

Speed of slower bus = x

After 3 hours, distance by faster bus = 3(x + 12)

Speed of slower bus = 3x

Since the towns are 576 km apart, then;

3(x + 12) + 3x = 576

Divide through by 3 to get;

x + 12 + x = 192

2x + 12 = 192

2x = 192 - 12

2x = 180

x = 180/2

x = 90 km/h

Faster bus speed = 90 + 12 = 102 km/h

Bond [772]

Answer:

k = 16 , (4, 0 )

Step-by-step explanation:

Using the discriminant Δ = b² - 4ac

• b² - 4ac = 0 , then 2 real and equal roots

Here

y = x² - 8x + k

with a = 1, b = - 8, c = k , then

b² - 4ac

= (- 8)² - (4 × 1 × k)

= 64 - 4k , and equating to zero

64 - 4k = 0 ( subtract 64 from both sides )

- 4k = - 64 ( divide both sides by - 4 )

k = 16

Then

y = x² - 8x + 16

Equate to zero to find the root

x² - 8x + 16 = 0 ← left side is a perfect square

(x - 4)² = 0

x - 4 = 0 ( add 4 to both sides )

x = 4

The point on the x- axis is (4, 0 )
