Answer:
Commutative Property of Addition: a + b = b + a
Step-by-step explanation:
The Commutative Property of Addition implies that even on changing the order of addition the final result (i.e. the sum) remains the same.
- Consider the addition of two numbers, say <em>a</em> and <em>b</em>:
a + b = b + a
Suppose <em>a</em> = 5 and <em>b</em> = 6, then:
<em>a</em> + <em>b</em> = 5 + 6 = 11
<em>b</em> + <em>a</em> = 6 + 5 = 11.
Thus, a + b = b + a.
- Consider the addition of three numbers, say <em>a, b</em> and <em>c</em>:
a + b + c= a + c + b = b + a + c = c + a + b
Suppose <em>a</em> = 4, <em>b</em> = 3 and <em>c</em> = 6, then:
a + b + c = 4 + 3 + 6 = 13
a + c + b = 4 + 6 + 3 = 13
b + a + c = 3 + 4 + 6 = 13
c + a + b = 6 + 4 + 3 = 13.
Thus, a + b + c= a + c + b = b + a + c = c + a + b.
For graphing make sure to shade the right portion and to make the line dotted like (— — — —)
the red is y>8x-4, the blue is y>-1/2x+1/2
2x-.25y < 1 is equal to 2x-1/4y < 1
multiply each side by 4:
8x-y < 4
add y to each side:
8x < 4+y
subtract 4 from each side:
8x-4 < y
rewrite:
y > 8x-4
4x+8y > 4
divide both sides by 8:
1/2x+y > 1/2
subtract -1/2x from each side:
y > -1/2x + 1/2
Answer: The approximate percent increase is 121.42857%. This is a rounded value. To get this, first you would need to find out which increased and in what direction. Of course, the 70 turned into an 85. So you can divide 85 by 70 and receive a number. Then in whatever form you found it, decimal, fraction, or even percent straight away, ensure the value is a percentage.
70 -> 85
85/70
About 1.21 [decimal]
1.21 x 100 = 121 [add the %]
121% [rounded]
