(2,-2)(5,7)
7-(-2)= 9
5-2= 3
9/3= 3
slope = 3
(you could also calculate the slope by just counting up how many units it goes up/down when you pick a point from the x-axis and move left/right. basically counting the rise over run)
You're almost finished.
(sin/cos) times cos = 0
Look at the left side. You could write it as (sin x cos) / cos = 0
and simply divide numerator and denominator by the cosine (cancel it).
Then what do you have left ? . . . <u>sin(x) = 0</u> Do I need to finish this for you ?
Answer:
Orange ribbon Zoe use is 
Step-by-step explanation:
Given:
Zoe had 3 1 /8 feet of orange ribbon. She used some ribbon to make a bow for a gift now she has 1 3 /8 feet of orange ribbon left.
Now, to find the orange ribbon Zoe use.
Let the orange ribbon Zoe use be 
Total orange ribbon Zoe had = 
Ribbon Zoe had left = 
Now, to get the orange ribbon Zoe use:

<em>Subtracting both sides by </em>
<em> we get:</em>

<em>Adding both sides by </em>
<em> we get:</em>






Therefore, orange ribbon Zoe use is 
So 10 questions is 100% you missed 30% of the questions so you would do 100%-30% which is 70%
It has 4 extinct variables in the equation.
