Answer: $4.50
Step-by-step explanation:
If she spent 10.50, and had 7.50 left, her total was 18.
$18/4=$4.50
Answer:
-429/629
Step-by-step explanation:
Use angle difference formula:
sin(x − y) = sin x cos y − sin y cos x
Assuming x and y are in the first quadrant:
sin(x − y) = sin x cos y − √(1 − cos²y)√(1 − sin²x)
Plugging in values:
sin(x − y) = (8/17) (12/37) − √(1 − (12/37)²)√(1 − (8/17)²)
sin(x − y) = (8/17) (12/37) − (35/37)(15/17)
sin(x − y) = -429/629
Answer: |x+2|={x+2;x≥−2−(x+2)
Step-by-step explanation:
: The absolute value function |x+2| can be defined as the piecewise function.
Combine like terms
a^2-4a^2=-3a^2
7a^3+11a^3=18a^3
Then put them back together from greatest exponent to smallest exponent
18^3-3a^2-a
The absolute value for -5 is 5 on a number line and 5 on a number line for absolute value is 5 if it is a negative number is is the same number but positive if it is a positive number the answer is that number
