Answer:
Step-by-step explanation:
walkway along diagonal=√(45²+28²)=√(2025+784)=√2809=53 ft
The transformation is done to y=1/x to get y=1/4x-12. We defined a turning point in the equation which will indicate the point in the graph.
We changed the form from y=x to y=x+c. In this case, we use 1/2 for the and constant C value which is -12.
In this task, we use the ratio. If amount of the discount is $ 79.80, the original price is much higher than the discount. Therefore, arrange the appropriate ratio as below and multiply on the cross:
y --> price (original)
x --> amount of discount
0,21x ----- 79,80$
x ----- y
0,21xy = 79,80x |:x
0,21y=79,80 |:0,21
y=380
The oryginal price is 380$
