Frederick is working on a number puzzle and discovers that the product of the two base numbers is exactly twice as large as the sum of those same base numbers. on this, ?

Let two base numbers that is any of the digit from [0-9] be x and y.

  It is given that,  the product of the two base numbers is exactly twice as large as the sum of those same base numbers.

→xy=2×(x+y)

There are two variables in the equation , and there is only one equation.So, we have to use Hit and Trial method to evaluate the value of x and y.

 → 0≤ x≤9 and 0≤ y≤9

⇒ Integral Solution of the above equation can be evaluated by drawing the graph  (Drawn the graph using Desmos)

1.⇒ x=4 and , y=4.

2.⇒ x=6 and y=3

3.⇒x=3 and y=6

4.⇒x=0 and y=0

this is answer of 144 cubic meters

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
