Answer:
c is the answer pi/9
Step-by-step explanation:so we have from 1 to 6.28
so 3.14 is there
3 is there
pi/9 is about 1/3 or less than 1 so not in between
pi squared/9 is about 9.something/9 so more than 1 over 1 and in between
I would multiply 4/7 by 5 and 3/5 by 7 to get 20/35 and 21/35. The Least Common factor is 35
Answer:

Step-by-step explanation:
So we have the equation:

First, let's distribute the left side of our equation:

Multiply:

Now, let's isolate the y-variable. Subtract 4y from both sides:

The right side cancels. Subtract on the left. So:

Now, subtract 5 from both sides:

The left side cancels. Subtract on the right:

Now, divide both sides by 6. So:

The left will cancel. Therefore:

And we're done!
Two straight lines perpendicular to each other, the slope of which is negative reciprocal.
y=-4/3x+b
The known points are put into the linear equation
y=-4+b
b=13
y=-4/3x+13
Answer: Option B

Step-by-step explanation:
The equation of a line has the following form:

Where m is the slope of the line and b is the intersection with the y axis
So the slope of the line
is 
By definition if two lines are parallel then they will have the same slope. Therefore the line parallel to
will have the same slope:

To find b we substitute point (3, 4) in the equation and solve for b



Then the equation is:
