A bank records deposits as positive numbers and withdrawals as negative numbers. Mike withdrew $50 dollars from his account three times one day. The next day he deposited 20 dollars 4 times. How much money does Mike have in his bank account?

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:

it could be 1,3 and more others to create a cylinder.

step-by-step explanation:

answer for #1 is c

answer for #2 is d

can i get brainliest

you can't solve x because it is 2 linear equation and you only have one equation
