On a recent day 8 euros were worth $9 and 24 euros were worth $27 write an equation of the form y equals kx to show the relation
attashe74 [19]

Answer:

y=8x/9

Step-by-step explanation:

Given that 8 euros were worth $9 and

24 euros were worth $27.

Let y represent the number of Euros and x no of dollars.

Given that the relation is of the form y = kx+C

When x=0 y =0,

i.e. C =0

Hence equation is of the form y = kx

Substitute x=8 and y =9

We get 9 = 8k

Or k =8/9

Hence relation is y=8x/9 is the relation between x and y.

WE can verify this for 27 dollars worth 24 euros.

24 =8/9(27) is true.

Thus equation is verified.

Kim's recipe for fruit punch calls for 3 cups fruit punch syrup to 4 cups of water. Tammy's recipe for fruit punch calls for 5 c
zhannawk [14.2K]
Tammy's recipe makes a sweeter fruit punch. This is because 3/4 (Kim's recipe) equals 18/24 (Tammy's recipe) and 5/6 equals 20/24 and since 20/24 is the bigger ratio, Tammy's recipe will make a sweeter fruit punch. I hope this helps. (:

What are the intercepts of y = 4x − 2?
maw [93]

Answer: y = −2

Step-by-step explanation:

  • To find the y-intercept, substitute in 0 for x and solve for y. Y = − 4 * 0 −2
  • Which then gives you y = - 2
