Answer:
2
Step-by-step explanation:
The given equation of line is
We need to find the slope of a line which is perpendicular to the given line.
The given equation can be rewritten as
...(i)
If a line is defined as , then the slope of the line is
In equation (i), a=3, b=6 and c=18. So, slope of the line is
Let be the slope of perpendicular line.
We know that product of two perpendicular line is -1.
Multiply both sides by -2.
Therefore, the slope of perpendicular line is 2.
Answer:
Explanation:
Given:
To Find:
Value of p=?
Solution:
Before solving this equation, we will use the method of BODMAS which states that we first solve the Bracket then Off then Division then Multiplier then addition and at last subtraction.
Now we will solve the both right and left hand side of the equation
Gruoping the like terms we get,
After solving the both right hand and left hand side of the equation
And we get the value of p as
Translating the words into formula, we have
In fact, we have that the pay rate is the total payment divided by the number of hours worked.
We can solve this formula for w in two steps: starting from the formula above, multiply both sides by w:
And then divide both sides by r:
