The pattern of the signs follows the acronym SOAP
S = same sign as the cubes
O = opposite sins of the cubes
AP = always positive

Step-by-step explanation:
Martha has 103 and together Sandra and Martha have 170 coins.
Well, first you need to decide what place you want to round it TO.
Example: Round it to the nearest hundredth:
The next larger hundredth is 186.29 .
The next smaller hundredth is 186.28 .
Now look at it.
186.282 is closer to 186.28 than it is to 186.29 .
So the nearest hundredth is 186.28 .
-- When 186.282 is rounded to the nearest hundredth, it becomes 186.28 .
Similarly . . .
-- When 186.282 is rounded to the nearest tenth, it becomes 186.3 .
-- When 186.282 is rounded to the nearest whole number, it becomes 186 .
-- When 186.282 is rounded to the nearest ten, it becomes 190 .
-- When 186.282 is rounded to the nearest hundred, it becomes 200 .
-- When 186.282 is rounded to the nearest thousand or anything larger,
it becomes zero.
I'm curious . . . where did this number come from ?
It happens to be one thousandth of the speed of light, in miles per hour.
Did it come up in science class, or did a science geek use it for
one of the problems in math ?
The answer is B because 40 goes into 220 5.5 times...
Answer:
Step-by-step explanation:
We know that f(-2)=7
x+4 = -2 <=> x = -6
so f(-6+4) = f(-2)=7
then the corresponding point is (-6,7)
