The cost of hot dog is $1.25
Step-by-step explanation:
Consider the provided information.
Seven hot dog (s )and two hamburger (s )cost $12.25;
Let the cost of hot dog is x.
The cost of hamburger is y.
Therefore,
......(1)
Two hot dog (s )and seven hamburger (s )cost $14.75.
......(2)
Use elimination method to solve the above equation.
Multiply equation 1 by 2 and multiply equation 2 by 7 and subtract them as shown:
Hence, the cost of hamburger is $1.75.
Now substitute the value of y in equation 1.
Hence, the cost of hot dog is $1.25
(-2,8) is the image point of A(8,2)
<h3>What is Rotation ?</h3>A rotation is a type of transformation which takes each point in a figure and rotates it a certain number of degrees around a given point.
As we know , the rule for rotation of is given by :-
(x,y)⇒(-y,x)
In the above formula (x,y) is the point of pre-image and (-y,x) is a point of image.
Since ,given point of pre-image : A(8,2)
After the rotation of , the image point are :-
(8,2) ⇒ (-2,8)
Therefore,
The image point of A(8,2) is (-2,8) .
