3. Describe how to create the graph of the direct-variation relationship "y varies directly with x where y = -8.4 when x = 4."

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)
