Answer:
17/20
Step-by-step explanation:
3/4 + 4/5 - 7/10
1. Find the LCD (Least Common Denominator). The LCD is 20.
2. 20/4=5. 5*3=15. So, 3/4 becomes 15/20.
3. 20/5=4. 4*4=16. So, 4/5 becomes 16/20.
4. 20/10=2. 2*7=14. So, 7/10 becomes 14/20.
5. Your new equation is 15/20 + 16/20 - 14/20.
6. Solve from left to right.
7. 15/20 + 16/20= 31/20.
8. 31/20 - 14/20= 17/20.
Rule: The sum of any integer and its opposite is equal to zero. Adding two positive integers always yields a positive sum; adding two negative integers always yields a negative sum. To find the sum of a positive and a negative integer, take the absolute value of each integer and then subtract these values.
The function is odd
Step-by-step explanation:
A function is odd when -f(x) = f(-x) for all values of x.
An odd function has the origin symmetry property .
Taking for example at x to be a point 1 unit to the right of the graph, then -x will be a point 1 unit left , a line joined from x to the curve downwards has the same length as a line joined from -x to the curve upwards.
