-9 because 2+7=9 so the negative part oh then must be -9
If x=1 and y=5 we get as 4product of 1+5=9
=4+5=9
9=9
lhs=rhs
The correct answer is C. One
Answer:
10y mm
Step-by-step explanation:
We would need to know the conversion of cm to mm.
We know
1 cm = 10 mm
If we are given a certain amount of centimeters (cm), to get the answer in millimeters (mm), we multiply that by 10. Example:
1 cm = 10 mm
4 cm would be 4 * 10 = 40 mm
23 cm would be 23 * 10 = 230 mm
Now, we are given "y" centimeters.
So, we multiply by "10" to get the answer in millimeters.
Hence,
y * 10 = 10y millimeters (mm)
The line is 10y mm
Answer:
- 1.375
Step-by-step explanation:
Each dot is worth -1/8 of a unit when moving left.
So the coordinates of the dark dot are - 1 and - 3/8
or - 1.375 . The word coordinates (plural) bothers me. It all depends on how you have been asked to represent these points. Another possibility is (-1.375,0). You have to choose from the examples you have been given. I wouldn't do that because you have not been given and xy graph.
