Yesterday, two friends went into a bank to open savings accounts. Zack started by putting $38 in his account, and he will deposit an additional $387 each week. Jamal made no initial
deposit, but he will add $406 more each week. In a few weeks, the friends will have the same
account balance. How many weeks will that take? What is that account balance?

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

lockers 1, 4, 9, 16, 25, 40, and 49 are open

i ran through it by the other answer is wrong

898.1666667

step-by-step explanation:

5389/6 = 898.1666667

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
