Answer:
is perpendicular to
and parallel to 
Step-by-step explanation:
First, convert the equation to standard form so that y is isolated.
x + 5y = 6 --> x - 6 = -5y (divide both sides by -5) --> 
A perpendicular line will have a slope that is the opposite reciprocal of the original slope (meaning you flip the numerator and denominator then make it negative).
is perpendicular to
which simplifies to 5.
A parallel line will have the same slope, but the y-intercept will be different. It can be pretty much any number as long as the original slope is used in the new equation.
is parallel to
just like
.
Answer:
12-9x
Step-by-step explanation:
Here, we want to write an algebraic expression from the given statement
Let us start with the product of 9 and a number x
What this mean is that we want to multiply 9 and x
That gives 9 * x = 9x
Now, 12 is decreased by this product means we are to subtract 12 from it
we have this finally as;
12-9x
125 degrees and 55 degrees
