Answer:
-1/3
Step-by-step explanation:
To find the slope, we can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( 9-10)/(10-7)
= -1/3
The missing number is 20
<h3>How to determine the number</h3>
We can see that the values at the top must be made equal to that at the bottom
For the top, we have
30 + 11 = 41
For the bottom, we should have:
21 + x = 41
Now, let's solve for 'x' to determine the missing figure;
21 + x = 41
collect like terms
x = 41 - 21
x = 20
Thus, the missing number is 20

I believe they compare because both butterflies can have a wingspan of 3.5 in. Hope this helps
You get imaginary roots for this equation.
x=4-5i
x=4+5i
