Answer:
xy < 60
Where x is the amount of subscription per month and y is the number of months
Step-by-step explanation:
Given Anna wants to spend less than $60 for the subscription
Let the amount of subscription per month be x
Let the number of months which Anna can enjoy her music be y
The total amount of money spent by Anna on subscription = ( The amount of subscription per month )( Number of months )
Total amount = xy
Given total amount < 60
So xy < 60
Therefore the above is the inequality recquired.
The answer to 392,196=4,508
Answer:
B. rotation 90° counterclockwise about the origin.
Step-by-step explanation:
Transformation is the process by which the size or orientation of a given figure is altered without any effect on its shape. Examples are; rotation, reflection, translation and dilation.
Rotation is the process of turning a figure about a reference point called the origin. While reflection is turning a figure about a line to produce its image.
In the given question, ∆ABC is mapped onto ∆A'B'C' by rotating it at 90° counterclockwise about the origin.
The radicand of a quadratic is b^2-4ac.
If it is greater than zero, there are two real solutions
If it is equal to zero, there is one real solution
If it is less than zero, there are no real solutions (though there are two imaginary solutions)
In this case the discriminant is 256-2160 so it is less than zero.
Therefore there are no real solutions, though there are two imaginary solutions, specifically (16±i√-1904)/18
