One kilometers is 1000 meters. so 2 times 1000 is 2000 meters. And since Sally rode 3000 meters she rode 1000 meters further.

Answer:

r=6

Step-by-step explanation:

$m=\frac{y2-y1}{x2-x1}$

m= -3

(2,8) (r,-4)

$-3=\frac{-4-8}{r-2}$

$-3r+6=-12$

$-3r=-18$

This is most likely C. The number of siblings doesn't really impact the test grade they got, for example, the first person had 1 sibling and got a 70, while the third person also has 1 sibling but got a higher score, a 93.

Answer:

d(t)=-10t-520

Step-by-step explanation:

First you have to find the gradient (m) using the formula $m=\frac{d(t)2-d(t)1}{t2-t1}$

using the two points you have been given: 1(3,-550) and 2(8,-600)

so you substitute these points into the equation $m=\frac{-600+500}{8-3}$

m=-10

Now that you have found the m-value you need to find the b-value by using one of the points you already have, I will use Point 2 (8,-600), and substitute it into the equation and solve

d(t)=-10t+b

-600=-10*8+b

-600=-80+b

-520=b

Therefore, the equation is d(t)=-10t-520

Courtney works at the local shoe store and receives $150 a week plus 3% of all sales over $1000. This week her sales were $3200.

The equation you would use to find her earning for the week would be:

y=0.03(x-1000)+150

This would mean she made $66 from commissions and $216 total.
