Evaluate the expression when x = 4 and y = 9.

1. xy
— =
3x

2. y + 19
——— =
x + 3

3. 5y - 6x =

4. 3xy - xy =

5. x + y
-—— =
y - x

6. x + y
——- =
2xy

7. 4x + 6y =

9x
8. 5xy + —— =
y

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts

is there a picture

step-by-step explanation:

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)

step-by-step explanation:

on the middle line
