Subtracting a number is the same as adding its additive inverse. For which elevation do we need to find the additive inverse?. W
Andreyy89

Answer:

Learning to subtract rational numbers by adding the additive inverse can be explained to your child as being the same as finding the opposite. This can even be described to your child as being a similar concept to one that they have worked with in the past where subtraction is the opposite of addition.

Additive inverse can be defined as adding a number with the opposite or the negative of that number to equal zero. The additive inverse of 1 is (-1), the additive inverse of 2 is (-2) and so on.

Example: 5 + (-5) = 0

In this example, (-5) is the additive inverse.

You can then take additive inverse one step when finding the additive inverse when subtracting rational numbers.

Example: 7 - 4 = 7 + (-4)

3 = 3

When finding the inverse, it is important to keep in mind that what you do to one side, you must do the opposite to another. In the example above, because you subtracted a positive four on one side, you are going to add a negative four to the other. This will make the equation equal on both sides.

If ax^3+9x^2+4x-10 when divided by x-3 leaves the reminder 5,then a=​
FinnZ [79.3K]

Let f(x) = ax³ + 9x² + 4x – 10

g(x) = 0⇒x - 3 = 0

⇒ x = 0 + 3

⇒ x = 3

On dividing f(x) by x - 3, it leaves a remainder 5.

Now keeping, f(3) = 5

⇒a(3)³ + 9(3)² + 4(3) - 10 = 5

⇒ a × 27 + 9 × 9 + 4 × 3 - 10 = 5

⇒ 27a + 81 + 12 - 10 = 5

⇒ 81 + 12 - 10 - 5 = 27a

⇒ 81 + 12 - 15 = 27a

⇒ 93 - 15 = 27a

⇒ 78 = 27a

⇒ a = 27/78

⇒ a = 0.3461

The length of a rectangle is 5 in more than double the width
Mekhanik [1.2K]

Answer:

length of a rectangle is 5 more than twice the length. I believe

you mean the length of a rectangle is 5 more than twice the

width.

From the information given we can make two equations,

thus forming a system to solve. We know the perimeter

of a rectangle is 2(length + width) and area = length*width.

length of a rectangle is 5 more then twice the width:

L = 2w + 5

The perimeter is 130:

2(L+w) = 130

L+w = 65

Since we know L=2w+5 we can substitute that into 2nd equation

to solve for w

2w + 5 + w = 65

3w = 60

w = 20

L = 2w+5 = 45

The area is length*width = 20(45) = 900 square units
