The value of y varies directly with the value of x, and y = –21 when x = 3.Which equations represent the relationship between y and x?

Choose exactly two answers that are correct.

Answers

directly means when x goes up by 3 then y goes up by 3
it is represented by
y/x=k where k stay the same
so y=-21
x=3

the equation is -21/3=-7
k=-7

so k =-7

therfor
y/x=-7
then manipulate the equation
multiply boht sides by x
y=-7x
subsitute valuse for x and get values for y
 if (x,y)
(1,-7)
(2,-14)
(3,-21)

so posiible equationscould be
-7/1=-7
-14/2=-7
-21/3=-7
and so on

Answer:

X=17

Y=62

Can someone help me with this? :)

Answers

C is the answer
Step by step explanation:
To get the answer you must expand the brackets (multiply the number or numbers outside the brackets with the ones within to remove them)
To do this you must first in 2(8+6) multiply 2 times 8 which is 16
Then you would multiply 2 times 6 which is 12
As the operation is a + that would mean the answer is 16+12
Hope this helps!
