A wild horse runs at a rate of 8 miles per hour for 6 hours. Let yy be the distance, in miles, the horse travels for a given amo

spin [16.1K]

Answer:

$0\leq x\leq 6$

$0\leq y\leq 48$

Step-by-step explanation:

we are given

speed =8 mph

time = 6 hours

so, we have

$x=6$

now, we can find distance

distance = (speed)*(time)

$distance=8\times 6 miles$

$distance=48 miles$

so, we have

$y=48 miles$

so, our range for x and y can be

$0\leq x\leq 6$

$0\leq y\leq 48$

Help me on number 15 please

Deffense [45]

You've already correctly labeled everything you need.

-- Ignore the lines YZ and YT .

-- That leaves you with the right triangle XYW .

-- Its legs are 8 and (12+3) = 15 .

-- XY is its hypotenuse.

I'm SURE you can finish it off from here.
