Answer:
it is a because you subtract the ten from both side and that makes the -8 into a -18 then you divide by 3 and your answer is -6
-8 3/8 = -8 15/40
-12 4/5 = -12 32/40 ,because you had to get a common denominator.
Since you are subtracting from a negative the negative turns into a positive.
-8 15/40 + 12 32/40 = 4 17/40
Answer: O 2 units left and 3 units down
Answer:
given statement is false
Step-by-step explanation:
given data
first time = 100 minutes
fourth time = 81 minutes
solution
as here time for 1st unit is multiply by learning percentage for obtain time for 2nd unit
so here time for 2nd unit divide by time of 1st unit so 100 is here learning curve
so 
× 100 = 81 percent
but it say 90 percent learning curve
so given statement is false
Answer:
c
Step-by-step explanation:
First, from A to B, x=6, but y ranges from 8 to -8. From B to C, y=-8, but x ranges from 6 to -6. From C to D, x=-6, but y ranges from -8 to 8. From D to A, y=8, but x ranges from -6 to 6.
The ranges are as follows:
- x goes from -6 to 6
- y goes from -8 to 8
There are no x values less than -6, no x values greater than 6, no y values less than -8, and no y values greater than 8. x is always greater than or equal to -6 and less than or equal to 6. y is always greater than or equal to -8 and less than or equal to 8. We can write these as inequalities as follows:
x ≥ -6
x ≤ 6
y ≥ -8
y ≤ 8
The answer that is not in these 4 is c. y ≤ -8. y is never less than -8, so this is wrong
