<span>xy = k

solve for k...

(8) * (8/3) = (64/3) = k

y = k / x

when x = 4,

y = (64/3) * (1/4) = (16/3)


Hope this helps!

Marys family had to pay 3$ for the car plus 2$ for each number of people in the car.
Gala2k [10]

Answer:

y=2x+3

Step-by-step explanation:

Y is the total amount that the family pays. 2x represents 2 dollars for every person (so, 2 multiplied by the number of people). Finally, 3 represents the initial amount that they must pay, no matter how many are in the car.

Write the vertex form of the equation and find the necessary coefficient to make it work.
.. y = a*(x +3)^2 -2
.. = ax^2 +6ax +9a -2

You require the y-intercept to be 7. So, for x=0, you have
.. 9a -2 = 7
.. 9a = 9
.. a = 1

The equation you seek is
.. y = x^2 +6x +7

What do the differences between the points (as shown on the graph) represent?
artcher [175]
The first one 7/2 represents the change in y over change in x.

For those kinds of questions I would refer to the change in y over change in x method.

Bullet 3 would work because 7/2 doesn’t result to 1. So that’s not the answer.

I hope that helps
