The additive inverse of (-3 9) is (3 -9). This means that if you add the two numbers together, the result is zero.
(-3 9) + (3 -9) = 0
The additive inverse of a number is a number that when added to the original number produces a result of zero. In other words, the two numbers have the same absolute value, but one is the opposite sign of the other.
For example, the additive inverse of (-3 9) is (3 -9). This means that if you add the two numbers together, the result is zero. To demonstrate this mathematically, (-3 9) + (3 -9) = 0.
The concept of additive inverse is important in mathematics because it is used to solve equations. By understanding the concept, you can quickly find the solution to an equation by adding the opposite of the number in question.
Furthermore, additive inverse is also important in understanding the concept of subtraction. Subtraction can be thought of as addition of the inverse of the number being subtracted. For example, if you subtract 3 from 9, you can also think of it as adding the inverse of 3 to 9, which would be (-3). Therefore, 9 - 3 = 9 + (-3) = 6.

Step-by-step explanation:
By what percent will a fraction change if its numerator decreases by 85% and the denominator decreased by 25%
Let x/y be the original fraction.
After decreasing the numerator by 50% and decreasing the denominator by 25%, the fraction is:
(x - 0.5x) / (y - 0.25y) = (0.5x) / (0.75y)
= (2/3)(x/y) = 66 2/3% of x/y
So, the fraction decreased by 33 1/3%.
The correct answer is 80%

In order to solve the system of equations below, Harvey multiplies each equation by a constant to eliminate the x
terms.
7x+ 3y = 5
2x+5v=-11
What are the resulting equations?
Answer:
14x + 6y = 10
14x + 35y = -77
Step-by-step explanation:
Multiply the top one by 2
14x + 6y = 10
Multiply the bottom one by 7
14x + 35y = -77
His next step is to subtract. You could have done this by multiplying the top one by -2
-14x - 6y = - 10
14x + 35y = -77 Now all you need do is add. The question now becomes what do you do? What answer do you give? I think the expected answer is the top two equations, but if I was actually doing the problem, I'd use the bottom 2.
Answer:
A) 14x + 6y = 10
-14x - 35y = 77
Step-by-step explanation:
multiple the first equation by 2 and the second equation by -7
2( 7x + 3y = 5)
-7( 2x + 5y = -11)
14x + 6y = 10
-14x - 35y = 77

Answer:

Step-by-step explanation:
In geometry, a vertex form is a point where two or more curves, lines, or edges meet. As a consequence of this definition, the point where two lines meet to form an angle and the corners of polygons and polyhedra are vertices. For example, a square has four corners, each is called a vertex.

2. The lengths of the sides of a triangle are 4cm, 5cm and 6cm. Find, in degrees to one decimal
place, the size of the largest angle of the triangle.
Answer:
82.8 degrees.
Step-by-step explanation:
The largest angle is opposite the longest side.
So we find the angle opposite the 6cm line using The Cosine Rule:
6^2 = 4^2 + 5^2 - 2.4.5 cos A
cos A = (6^2 - 4^2 - 5^2) / (-2*4*5)
= -5/ -40
= 0.125.
So m angle A = 82.819 degrees.
