Answer: $31.25
altogether she spends... 12.5×$4.50= $56.25
in total, she makes 5 beds ( 12.5÷2.5=5)
so she makes 5×$17.50= $87.50 from selling the beds.
however, $87.50-$56.25= $31.25
Using the slope concept, it is found that the distance the plane traveled from point A to point B is of 14,475 feet.
<h3>What is a slope?</h3>
- The slope is given by the <u>vertical change divided by the horizontal change</u>.
- It's also the tangent of the angle of depression.
At point A:
- Altitude of 6700 feet, which is the vertical change.
- The horizontal position we want to find is
.
Hence:



At point B:
- Altitude of 6700 feet, which is the vertical change.
- The horizontal position we want to find is
.
Hence:



Then, the distance is of:

Answer:
-y^2
Step-by-step explanation:
x(x-2y)-(y-x)^2=
Distribute
x^2 -2xy -(y-x)^2=
Foil
x^2 -2xy -(y^2 -2xy+x^2)=
Distribute the minus sign
x^2 -2xy -y^2 +2xy-x^2=
Combine like terms
-y^2
The answer is 7, because 0.875*8= 7
