2 x 5= 10
Answer:When x=16 , y=36 . Explanation: If y varies directly as x , then if y increases, x increases, and if y decreases, x decreases.
Step-by-step explanation: because
The input is the x value. The output is the y value. The question is asking for a function which will give you the output when the x value is plugged in. The input is increasing by 1 each time. The output is decreasing by 3 each time. -3÷1=-3. Therefore, x is going to be multiplied by -3. However, -3x does not equal the Y-value so one must determine if something is being added. -3×1=-3 =/= -1. However, (-3×1)+2=-1. -3x+2 is a possible function of Y. To check, one can plug in the rest of the X values to determine if the answer will be equal to the Y value given in the table.
Therefore: Y=-3x+2.
First, calculate the ones that is in the bracket, 4/5×1/3 = 4/15 (make the denominator the same), second finish the question, 7 - 4/15.
Answer, 6&11/15. (six and eleven over fifteen.
