Answer:

consider : (7, 0)  \: and  \: (0, 70) \\ m =  \frac{(70 - 0)}{(0 - 7)}  \\ m =  - 10 \\ y = mx + c \\ 0 = ( - 10 \times 7) + c \\ c = 70 \\  \therefore \:  \: y =  - 10x + 70

The graph of a proportional relationship is shown. What is the
arlik [135]

Answer:  B) $47/week

===========================================================

Explanation:

Because the graph goes through the origin, we can simply divide the y value over the x value. Do so for any point on the diagonal line.

For example, picking (x,y) = (2, 94) leads to k = y/x = 94/2 = 47 being the constant of proportionality and also the amount of savings per week.

You can think of it like this:

2 weeks = $94 in savings

2/2 weeks = $94/2 in savings ... divide both sides by 2

1 week = $47 in savings

leading to the savings rate of $47 per week

----------

Side note: This linear equation is y = 47x. It is in the form y = kx with k = 47. It is a direct proportion equation. The constant of proportionality is also the slope. All direct proportion equations are linear and go through the origin.

Bruno's Bakery uses 4/9 of a barrel of raisins each day. Cosmo's Bakery uses 6/5 as many raisins as Bruno's Bakery. How many bar
alexgriva [62]
First of 3/7 of a week is 3 days because there are 7 days in a week e out of seven so you get it?

1. The question is asking you how much barrels of raisins is used in three days but first you need to find out how much they use in 1 day (this is how I would do it) so turn all the fractions into a decimal

4/9 = 0.4444...
6/5= 1.20
3/7= 0.43

So now you got your decimals

2. Multiply 0.4444 by 1.20 now you got how much you get a day for cosmos bakery which is 0.53

3. Now go back to the 3/7 of a week which is 3 days and now you need to multiply 0.53 by 3 and you will get your answer

ANSWER!

1.59 a day for cosmos bakery

I HOPE THIS HELPED YOU TO SOLVE THIS PROBLEM AND SOME FUTURE ONES!
