Question

If Ralph skis 4 km during week 7 and jake is at his goal which statements true

Answer 1

Answer:

Option 2 is correct.

Step-by-step explanation:

We have been give the graph of the skis

x axis represents number of weeks.

And y-axis represents kilometers.

Purple line showing ski of Jake

Ad blue line showing ski of Ralph.

Ralph was uniform during the week.

So we ca see that the Jake skiing more than Ralph.

Or Ralph is skiing less than Jake

Therefore, Option 2 is correct.

Answer 2

Answer with explanation:

⇒Equation of curve which represent Jake

 Equation of Line Passing through , (0,2) and (2,3).

$\frac{y-2}{x-0}=\frac{3-2}{2-0}\\\\2 \times (y-2)=1 \times x\\\\ 2 y -4 =x\\\\x-2 y +4=0$

x -2 y +4=0,is the Linear equation which represent Jake.

⇒⇒⇒Equation of curve which represent Ralph

Line Passing through , (0,4) .

→y=4,is the equation which represent Ralph.

Ralph is moving with Constant Speed.

If you compare Ralph and Jake

X axis =Number of Weeks

Y axis =Distance in Kilometers

⇒For Ralph ⇒At, x=0, y=4,

at, x=1 ,y=4,.......at, x=7,8..., y=4.

⇒For Jake ⇒At,x=0, y=2, at,x=2, y=3,at,x=8,y=6.

Option B:

Ralph is skiing less than Jake.
