The given lines are perpendicular
Step-by-step explanation:
if Two lines are perpendicular then their slopes are
m
Where m₁ is slope of first line and m₂ is the slope of second line.
Since the lines are in slope-point form the standard form is:

where m is the slope
The slope of first line y= -9/5x + 1/5 is: m₁ = -9/5
The slope of second line y= 5/9x + 2/9 is: m₂= 5/9
So, m
i.e 
So, The given lines are perpendicular

Answer:
120.25
Step-by-step explanation:
4 to the third power is 64. so 64 + 9 = <u>83</u>. 20-8 = <u>18</u>. 6 + 2 = <u>8</u>.
so 83 + 18 + 8 = 109. so 8 divided by 18 = 2.25. 109 + 9 + 2.25 = <u>120.25.</u>
Answer:
Step-by-step explanation:
The rate of change is defined as the derivative of the function, or also known as the slope. The derivative here would be 3. Another function which has the same rate of change would be any function with a slope of 3. A few example are:
f(x) = 3x + 1
f(x) = 3x + 2
Answer:

Step-by-step explanation:
we would like to solve the following equation:

notice that, the fraction can be reduced therefore reduce fraction:


by trigonometric value table we obtain:

get rid of sin:

and we are done!
