Answer:
C.
yes; y = 1.8x
Step-by-step explanation:
Answer for the question :
Yes, Y varies directly with X, and the equation is :
Y = 1.8X
NOTE : For every value of X, when you multiply them with 1.8, you will get the corresponding Y.
Y = 1.8 x X
5.4 = 1.8 x 3
12.6 = 1.8 x 7
21.6 = 1.8 x 12 (Q.E.D.)
That’s the answer, good luck in solving the question!
:-)
ideal all you ought to do is to divide the y via potential of x and u get the equation working occasion #a million y=32 / x=4 then u have y/x=32/4 ----> y=8x and do the comparable indoors something so #2 y=-20 & x=-20 so y/x=-20/-20 y=x etc
The slope is -10, I used a graph for this.
Answer:
Tree c
Step-by-step explanation:
For this case we have that an inverse variation in a function is given by:

For this case, we must find the value of the constant k.
To do this, we substitute the values of x = -4, y = 8.
We have then:

Clearing k we have:

Substituting the value of k we have that the inverse variation is:
