5 I think, cause if your 3/4 ways done you need to walk 1/2 more kilometers to be finished... So if you add 1/2 to 41/2 it equals 5

The ordered pair (a,b) satisfies the inequality y>x+10. Which statement is true?

Morgarella [4.7K]

Answer:

$b-a>10\\\\Difference\ of\ b\ and\ a\ is\ greater\ than\ 10.$

Step-by-step explanation:

Ordered Pair: In an ordered pair (p,q) first value that is p represents x-value and second value(q) represents y-value.

$Given\ inequality\ y>x+10\\\\Ordered\ pair (a,b)\ satisfies\ the\ inequality\\\\Hence\ x=a,\ y=b\\\\Substitute\ these\ values\ in\ the\ inequality.\\\\b>a+10\\\\\Rightarrow b-a>10\\\\That\ means\ difference\ of\ b\ and\ a\ is\ greater\ than\ 10.$

Hello from MrBillDoesMath!

Answer:

The fourth choice, b = +\- sqrt( sg + a^2)

Discussion:

s = (b^2 - a^2)/g => multiply both sides by "g"

sg = b^2 - a^2 => add a^2 to both sides

sg + a^2 = b^2 => take the square root of each side

b = +\- sqrt( sg + a^2)

which is the fourth choice.

Thank you,

MrB
