Complete Question Statement:

QUESTION 4

Select the equation in which you use the zero property of multiplication to find the solution.

A.) (20 x 1/20) - 7 = -6

B.) (4/7 X 7/4) - 8 = -7

C.) (- 1/6 x 0) + 8 = 8

D.) [7 x (6/7 - 5/7)] + 4 = 5

Answer:

Option C i.e. C.) (- 1/6 x 0) + 8 = 8 is the correct option in which you use the zero property of multiplication to find the solution.

Step-by-Step Explanation:

The multiplication property is said to be the property which states that the result of any product number would be zero, if any number of the product is multiplied with zero.

For example, if you multiply 4 with zero, you answer will be zero.

i.e. 4 x 0 = 0

Whatever the number you have, the result will be always be zero if you multiply it with zero.

Out of all the given options, only option C a clear answer as it involves the zero multiplied with - 1/6.

So, the product of 0 and - 1/6 would be zero i.e. 0 x - 1/6 = 0

As - 1/6 x 0 = 0, hence, the complete equation would be computed as:

(- 1/6 x 0) + 8 = 8

0 + 8 = 8 ∵ - 1/6 x 0 = 0

8 = 8

So, the equation becomes true when substitute - 1/6 x 0 = 0 in it.

Therefore, Option C i.e. C.) (- 1/6 x 0) + 8 = 8 is the correct option in which you use the zero property of multiplication to find the solution.

(2x-1)(x+4)=0

Step-by-step explanation:

A random zero property of multiplication is taken to find the solution

(2x-1)(x+4)=0

consider a=2x-1 and b=x-4 a.b=0

either a or b or both must be 0

equating both the equations

2x-1=0 or x=4=0 x-4=0

2x-1=0 x=4

2x=1

x=1/2

substitute the values of x in the main equation

[2(1/2)-1][(1/2)+4]=0

Increase 15837.77 by 8.5% give your answer rounded to 2 D.P

artcher [175]

Given:

Increase 15837.77 by 8.5%.

To find:

The answer rounded to two decimal places.

Solution:

We have,

Initial value = 15837.77

Increasing percent = 8.5%

Now, the value after increasing by 8.5 % is

$\text{Required value}=15837.77+\dfrac{8.5}{100}(15837.77)$

$\text{Required value}=15837.77+1346.21045
$

$\text{Required value}=17183.98045
$

Round the value to two decimal places.

$\text{Required value}\approx 17183.98
$

Therefore, the required value is 17183.98.

Two lines intersect in more than one point always sometimes never

GuDViN [60]

The answer is never, that is, on a 2 dimensional plane. You can perform an experiment to see why it is the case. On curved surfaces though, two lines can intersect one another more than once. For instance, on the surface of planet Earth, two lines can intersect one another, both at the Earth's North Pole and South Pole.
