2r + 2 = 10
r=?

Hurry Please!!

2r+2=10

Step-by-step explanation:

R is 4

u would do 2*4

that equals 8

next add 2+8

you get 10

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

graph of this function as shown below:

the discriminant is 64 + 4*1*12 = 112

this is prime.
