Two bikers, Derek and Tina, start riding from the same location. Derek rides due west for x miles. Tina goes due south and cover
kirza4 [7]

Answer: Tina rides 4 miles and Derek rides 3 miles.

Explanation:

Since we have given that

Distance covered by Derek in west direction be x

Distance covered by Tina in south direction be x+1

Distance between the bikers when they both stop is x+2

Since it forms right triangle, so we will apply "Pythagorus theorem":

H^2=P^2+B^2\\\\(x+2)^2=x^2+(x+1)^2\\\\x^2+4x+4=x^2+x^2+1+2x\\\\x^2+4x+4=2x^2+2x+1\\\\x^2-2x^2+4x-2x+4-1=0\\\\-x^2+2x+3=0\\\\x^2-2x-3=0\\\\x^2-3x+x-3=0\\\\x(x-3)+1(x-3)=0\\\\(x+1)(x-3)=0\\\\x=-1,3

Since distance can't be in negative sign, so we take x=3 miles

Derek rides 3 miles

Tina rides is given by

x+1=3+1=4\ miles

Hence, Tina rides 4 miles and Derek rides 3 miles.

Which set of ordered pairs does not represent a function?
Vesna [10]

Answer:

C

Step-by-step explanation:

In a function, each domain has one range. But a range can have many domains.

Think about it like this:

Patty is eating dinner

Patty is swimming

<em>Both can't happen at the same time. </em>

<em>But:</em>

Patty is eating dinner

Leo is eating dinner

C has two domains of -3, each having different ranges.

Hope that helps, tell me if you need further info. =)
