Is this what you are asking?
To write a line that is perpendicular you have flip the slope and change the sign so it would be -1/2, then you carry on like normal. So the answer is:
y-6= -1/2(x-9)
Answer:
<em>s</em> = 87.5
Step-by-step explanation:
We start with 170 + 35 - 5 = 2<em>s</em> + 25
We want to find the value of <em>s. </em>Since one side of the expression (170 + 35 - 5) isn't simplified yet, that's what we should start with.
Evaluate: 170+ 35 - 5
170 + 35 - 5 = 200
Now our equation is 200 = 2<em>s</em> + 25
Solve using algebraic methods:
Start by subtracting 25 from both sides of the equation to get:
175 = 2<em>s</em>
Then, divide both sides by 2:
87.5 = <em>s</em>
The final answer you get should be <em>s </em>= 87.5
Hope this helps!
