Slope is the difference in y over the difference in x, or 23--21 / -4-7 = 44/-11 = -4
using the first point we get
y--21=-4(x-7)
y+24 -4(x+ -7)
-7 goes in the? box
The answer to this expression is 40. Why? Well, we can use PEMDAS in this expression.
P: Parenthesis
So this is our first step:
28 / 4 = 7
Next step: Simplify.
7 + 3 + 6 x 5
Then: E stands for Exponents but we have none so we can move on.
M stands for Multiply so we have our next step:
6 x 5 = 30
Now: Simplify.
7 + 3 + 30
Now that we have a simple equation, we can add the values to get our answer.
7 + 3 = 10
10 + 30 = 40
Therefore, your answer is 40. Whenever you see problems like this, be sure to use PEMDAS for a faster and more accurate evaluation.
Your final answer: 40.
In a circle, a radius perpendicular to a chord bisects the chord.
So
BC = CA
BC = 6 (given)
x (or AC) = 6
Answer = 6 plz tell me if this helps you.
