Helen borrowed money from her aunt to pay for college expenses. The graph below shows the amount left
enot [183]

Answer:

y = -100x + 13000

Step-by-step explanation:

See attachment for graph

First, we need to take any corresponding values of x and y

(x_1,y_1) = (0,13000)

(x_2,y_2) = (130,0)

Next, we calculate the slope (m)

m = \frac{y_2 - y_1}{x_2 - x_1}

m = \frac{0 - 13000}{130 - 0}

m = \frac{- 13000}{130}

m = -100

Next, we calculate the line equation using:

y - y_1=m(x-x_1)

y - 13000 = -100(x - 0)

y - 13000 = -100x

Make y the subject

y = -100x + 13000

Hence, the line equation is:

y = -100x + 13000

Brandons backpack weighs 3140 grams. Brandon weighs 22 kg 610 grams more than his backpack. if Brandon got on a scale how much w
Doss [256]

Brandon's backpack weighs = 3140 grams.

We know, 1000 grams in a kilogram.

Therefore, 3140 grams = 3000 grams + 140 grams = 3 kilogram 140 grams.

Brandon weighs(without backpack) = 22 kg 610 grams more than his backpack.

More than pharse represents addition.

22 kg 610 grams more than backpack weighs = 22 kg 610 grams + 3 Kg 140 = 25 Kg 750 grams.

Therefore, Brandon weighs(without backpack) = 25 Kg 750 grams.

Total weight of Brandon weighs and backpack weighs = Brandon weighs(without backpack) + backpack weighs.

= 25 Kg 750 grams + 3 Kg 140 grams

= 28 Kg 890 grams.

Therefore, Brandon got 28 Kg 890 grams on a scale when wearing his backpack.
