Answer:
C. √3
Step-by-step explanation:
When one of the factors is a rational number (0.5), the product will be irrational if, and only if, the other factor is irrational.
Of the numbers offered, only √3 is irrational.
√3 will produce an irrational product when multiplied by 0.5.
__
The other values are all rational:
A: 4
B: 5/9
D: 1/3
Answer:
See below
Step-by-step explanation:
Perpendicular lines have slopes which are negative reciprocals. When the slopes are multiplied like 3 and -1/3 is -1.
This means the line y = -6x + 7 which has slope -6 will have a perpendicular line that has slope 1/6.
Any equation which has slope 1/6 is a solution.
Example 1/6x - 1 or 1/6x + 7 or etc.
Answer: 10
Step-by-step explanation:
Since angle 2 is 120 degrees, the corresponding angle is 6, so 6 will also be 120 degrees
6 and 8 should form 180 degrees
180 - 120 = 60
so angle 8 is 60 degrees
