Answer:
The cost of each pair of shoes before the discount=$67.65
Step-by-step explanation:
Step 1
Use the expression below to determine original cost of the 2 pairs of shoes as follows;
A=O-R
where;
A=total bill after discount
O=original cost of 2 pairs of shoe
R=discount amount
In our case;
A=$110.50
O=unknown=x
R=15% of O=(15/100)×x=0.15 x
replacing;
115=x-0.15 x
115=0.85 x
x=115/0.85
x=135.294
Original cost of the 2 pairs of shoes=$135.294
Original cost of a pair of shoes=135.294/2=$67.65
The cost of each pair of shoes before the discount=$67.65
If you had 25 buttons ( red coloured) and 77 buttons (blue coloured). Half of the blue ones melted due to a supernova in the Atlantic ocean. Multiply red and blue buttons :)
Answer:
3
Step-by-step explanation:
The X-intercepts are the places where the line crosses the x axis which is the one that goes along so they would be 5 and -5.
the Y-intercepts is the place where the lines cross the y axis which is the one that goes up. so for this question it is 5.
i’m not sure about the domain or the range.
