Answer:
-8b-11w+10
Step-by-step explanation:
The first term has a variable b
The second term has a variable w
The third term is a constant
They cannot be combined
1/5, 5/8, 2/3 from least to greatest.
1/5 = 0.20 x 100% = 20%
5/8 = 0.625 x 100% = 62.50%
2/3 = 0.667 x 100% = 66.70%
It is easier to convert dissimilar fractions into decimals to know which fraction has greater or lesser value compared to the other fractions.
When in point-slope form, the number next to the y and the x by themselves will be the opposite of what they would actually be as coordinates. This means that the y-coordinate, -1, will show up as y+1. This eliminates A and B out of the choices.
The slope is -3, which will be the number outside of the parentheses, which is what we see in C’s answer or -3(x-10).
Therefore, the answer is C: y+1 = -3(x-10).
Answer:
12 cm
Step-by-step explanation:
The rule regarding secants and/or tangents is that the product of distances from their common point to the two intersection points with the circle is the same.
For the tangent the "two" intersection points with the circle are the same point, so ...
product of tangent lengths = product of secant lengths
(8 cm)(8 cm) = (4 cm)(4 cm +x)
Dividing by 4 cm gives ...
16 cm = 4 cm + x
12 cm = x
