chad wants to buy some books over the internet. each book costs $10.01 and has a shipping cost of $9.96 per order. if chad wants
Serga [27]
If you would like to find the inequality that shows the maximum number of books that he can buy, you can do this using the following steps:

p ... number of books

$10.01 * p + $9.96 <= $50
10.01 * p + 9.96 <= 50
10.01 * p <= 50 - 9.96
10.01 * p <= 40.04
p <= 40.04 / 10.01
p <= 4 books

The correct result would be <span>9.96 + 10.01p ≤ 50, so p ≤ 4.</span>

Find two numbers whose difference is 13 and whose squares when added is 449.

X, y - the numbers

x-y=13 \\&#10;x^2+y^2=449 \\ \\&#10;\hbox{solve the first equation for x:} \\&#10;x-y=13 \\&#10;x=13+y \\ \\&#10;\hbox{substitute the result for x in the second equation:} \\&#10;(13+y)^2+y^2=449 \\&#10;169+26y+y^2+y^2=449 \\&#10;2y^2+26y+169-449=0 \\&#10;2y^2+26y-280=0 \ \ \ \ \ \ \ \ \ \ \ |\div 2 \\&#10;y^2+13y-140=0 \\&#10;y^2+20y-7y-140=0 \\&#10;y(y+20)-7(y+20)=0 \\&#10;(y-7)(y+20)=0 \\&#10;y-7=0 \ \lor \ y+20=0 \\&#10;y=7 \ \lor \ y=-20

x=13+y \\ \Downarrow \\ \hbox{for } y=7: \\&#10;x=13+7 \\&#10;x=20 \\ \\&#10;\hbox{for } y=-20: \\&#10;x=13-20 \\&#10;x=-7 \\ \\&#10;(x,y)=(20,7) \hbox{ or } (x,y)=(-7,-20)

The numbers are 20 and 7 or -7 and -20.

Answer:

  8

Step-by-step explanation:

The Pythagorean theorem tells you of the relation ...

  x² + 6² = 10² . . . . . . . . . squares of sides total to the square of hypotenuse

  x² = 100 -36 = 64 . . . . . subtract 6²

  x = √64 = 8 . . . . . . . . . . square root

The length of side x is 8 units.
