Create 2 lines thatare parallel to 8x + 2y = 7?
Alinara [238K]

d1 = ax + by + c = 0 and d2= mx + ky + f = 0

if they are parallel :

\frac{a}{m} = \frac{b}{k} \neq \frac{c}{f}

8x + 2y = 7

8x + 2y - 7 = 0

  • 8x + 2y -9 = 0
  • 4x + y -6 = 0
  • 16x + 4y - 19 = 0

you can create more whatever you want =)

Hope this helps ^-^

an open box is to be made from a two-foot by three-foot rectangular piece of metal by cutting equal squares from the corners and
tensa zangetsu [6.8K]

The volume for the largest box will be 1.056 foot³. This can find out by application of differentiation.

What is AOD?

AOD is nothing but application of differentiation. It implies scopes where we can use differentiation to make our calculations easy.

Here, given

Length and breadth = 2,3 foot

Let us consider length of side of square = x

So, after cutting squares left sides of rectangular sheet = 2-2x , 3-2x

So, volume = (2-2x)*(3-2x)*x

                v = 4x³ - 10x² + 6x

To find largest volume , \frac{dv}{dx} = 0

                 \frac{dv}{dx} = 12x² - 20x + 6

                12x² - 20x + 6 = 0

                x = 0.4 , 1.3

But, for 1.3 volume will be negative i.e. not possible.

So, volume = 2.2*1.2*0.4

                   = 1.056 foot³

if thrice my age 6 years ago be subtracted from twice my present age the result is present age then my present age is what​
aleksley [76]

Answer:

9 years

Step-by-step explanation:

Let the present age = x

Age 6 years ago = x - 6

Thrice my age 6 years ago = 3*(x -6) =3x - 3*6 = 3x - 18

Twice my present age = 2 *x = 2x

Thrice my age 6 years ago be subtracted from

twice my present age  = 2x -  (3x - 18)

2x - (3x - 18) = x

2x - 3x  + 18 = x                  

    -x  + 18 = x              {Add x to both sides}

             18 = x + x

              18 = 2x              {Divide both sides by 2}

           18/2 = x

x = 9 years
