Absolute value is a term which is used to indicate the distance of a point or number from the origin of a number line or coordinate system.
Suppose x is a real number. Then the absolute value of x is defined as follows:
For x = 0 or x > 0, | x | = x
For x < 0, | x | = - x
Now, we have to find the absolute value of the given number 
that means we have to find the distance of from the origin of a number line.
Distance of 
from the origin is 
. As distance can never be negative.
Therefore, the absolute value of is .
If a toy that costs $2.99 is at a 30% discount then you first need to make 30% a decimal.
30% = .3
Now multiply $2.99 by .3 to find the discount which is .897
Since .897 has a thousandths place we need to round that which would make it 90 cents.
Now we know there is a 90 cent discount on a $2.99 toy.
take $2.99 - 90 cents = $2.09
The toy costs $2.09 after a 30% discount
Answer:
875
Step-by-step explanation:
The given expression is
-2x² + 17 - 15x + 7xy
The algebraic expression may be written as
-2x² + 7xy - 15x + 17
The constant term does not contain either x or y.
Therefore 17 is the constant term.
Answer: 17
Answer:
Step-by-step explanation:
The center is at (2,-7). The radius is 2.
(x-2)² + (y+7)² = 2²
