Remark
This is an excellent question. Estimation is a powerful skill to have. People should always shop using estimates. Try it to see what happens.
x = 11.7 which rounds up to which we will call x1 and that is 12
y = 6.03 which round down to 6 which we will call y1 and that is 6
Now x - y = 5.67
If you do the rounded subtraction x1 - y1 = 12 - 6 = 6
The estimate is not zero. D is not correct.
There is enough information E is not the answer.
B is wrong, her estimate is larger than x - y
C is wrong the two subtractions are not equal.
A is correct and always will be no matter what numbers are chosen
A <<<< Answer
Answer:
90%
Step-by-step explanation:
If you are going to find out the percent of the car that do not have 4 wheel drive, you take the total amount of car that passed though the stoplight which is 100% . You take this 100% and then subtract the 10% to get the final answer 90%. 90% of the cars do not have 4 wheel drive.
When a line is given in the form
The slope of the line is m. So, in this case, the slope of 
is 1.
Given a slope 
, you find the slope of a perpendicular line 
by imposing
So, if the given line has slope 1, a perpendicular line has slope given by
and thus 
So, we want a line with slope -1 and passing through (12,-1). Using the fomula
we get
Answer:
y= 4x + -6
