Answer:
Step-by-step explanation:
We have the two points: (2, -3) and (k, 7).
And we want to find the value of k such that the slope between these two points is -1.
So, we can use the slope formula:
Let (2, -3) be (x₁, y₁) and let (k, 7) be (x₂, y₂). Let's also substitute the slope m for -1. This gives us:
So, let's solve for k. Add in the numerator:
Notice that we can rewrite the left side as:
Now, we can cross-multiply:
Divide both sides by -1. This removes the negative on the left:
Finally, add 2 to both sides. So, the value of k is:
And we're done!
Answer:
The fraction is 470/1000, which can be simplified to 47/100, and that is 47%.
Step-by-step explanation:
Basically you take what is asked for and you divide it by the total amount.
470 is the amount of girls as contestants.
1000 is the total amount of contestants.
And that gives you the ratio 470/1000.
