9. Which property is illustrated by (6 x 5) x 4 =6 x (5 x 4)?

Advocard [28]

For this case we have that by definition:

$(a * b) * c = a * (b * c)$

Indicates an example of the associative property of multiplication.

$(6 * 5) * 4 = 6 * (5 * 4)\\30 * 4 = 6 * 20\\120 = 120$

Similarly, we observe the associative property of multiplication

A truck driver who covers the interstate in 4 1/2hours traveling at the posted speed of 55 mph. If the speed limit is raised to

kotegsom [21]

Answer: The same trip will require 3.8 hours.

Step-by-step explanation:

Since we have given that

Time = $4\dfrac{1}{2}=\dfrac{9}{2}$

Speed = 55 mph

So, distance would be

$Speed\times time=55\times 4.5=247.5\ miles$

If the speed limit = 65 mph

So, time will be

$\dfrac{247.5}{65}=3.8\ hours$

Hence, the same trip will require 3.8 hours.

Determine the equation of the line with slope −2 that passes through the point M(−1, −3).

saveliy_v [14]

The slope formula: y = mx +b
m = -2, therefore we have: y = -2x + b
The line passes throught the point M(-1, -3) → x = -1, y = -3.
Substitute to the equation:
-3 = -2 · (-1) + b
-3 = 2 + b |-2
b = -5
y = -2x - 5 |+2x
Answer: 2x + y = -5
