Answer:
$3.50
Step-by-step explanation:
Given:
1 sharpener + 2 posters = $28.99
1 sharpener = $21.99
1 poster = ?
Solve:
1 sharpener + 2 posters = $28.99
$21.99 + 2 posters = $28.99
2 posters = $28.99 - $21.99
2 posters = $7
1 poster = $7/ 2 = $3.5
The repair amount ($5800) is less than 80% of the blue book value of Michelle's car.
Answer:
6 units
Step-by-step explanation:
the horizontal difference is the distance between the x values of both points. we know the distance between 4 and -2 is 6.

Amplitutde:

Normally for sinx amplitude is 2 (1 +1). In the case when it is half sine amplitude is halved, therefore 0.5 +0.5 = 1 Paramers alpha = 2x does not matter because it only stretches the graph horizontally.
The domain of the function is all real numbers except 2 and -1
Step-by-step explanation:
Domain is the set of inputs of a function on which the function is defined.
Given function is:

In case of a function involving fraction, the function is undefined if the denominator is zero so in order to find the domain of the function algebraically , we have to find the values on which the function will be undefined

The function will be undefined on x=-1 and x=2
So,
The domain of the function is all real numbers except 2 and -1
