Answer

-4y - 67 = y - 17


Step by step explanation

Let y be the unknown number.

-4 times a number minus 67 is equal to 17 less than the number.

The number is y

times means multiplication

-4y - 67 = y - 17

Hope you will understand the concept.

Thank you.

<u>Answer:</u>

-4y - 67 = y - 17

<u>Step-by-step explanation:</u>

We are given y to be assumed as the unknown number here in this word problem.

So we will establish the equation step by step.

-4 times a number: the number y is multiplied by -4 to give -4y

minus 67: 67 is subtracted from -4x to give -4y - 67

is equal to 17 less than the number: it means that half of the already constructed equation is equal to y - 17

so the full equation will be:

-4y - 67 = y - 17

jenna's rectangular garden borders a wall. she buys 80 ft of fencing. what are the dimensions of the garden that will maximize i
FrozenT [24]

Answer:

The  dimensions are x =20 and y=20 of the garden that will maximize its area is 400

Step-by-step explanation:

Step 1:-

let 'x' be the length  and the 'y' be the width of the rectangle

given Jenna's buys 80ft of fencing of rectangle so the perimeter of the rectangle is    2(x +y) = 80

                         x + y =40

                               y = 40 -x

now the area of the rectangle A = length X width

                                                  A = x y

substitute 'y' value in above A = x (40 - x)

                                              A = 40 x - x^2 .....(1)

<u>Step :2</u>

now differentiating equation (1) with respective to 'x'

                                      \frac{dA}{dx} = 40 -2x     ........(2)

<u>Find the dimensions</u>

<u></u>\frac{dA}{dx} = 0<u></u>

40 - 2x =0

40 = 2x

x = 20

and y = 40 - x = 40 -20 =20

The dimensions are x =20 and y=20

length = 20 and breadth = 20

<u>Step 3</u>:-

we have to find maximum area

Again differentiating equation (2) with respective to 'x' we get

\frac{d^2A}{dx^2} = -2

Now the maximum area A =  x y at x =20 and y=20

                                        A = 20 X 20 = 400

                                         

<u>Conclusion</u>:-

The  dimensions are x =20 and y=20 of the garden that will maximize its area is 400

<u>verification</u>:-

The perimeter = 2(x +y) =80

                           2(20 +20) =80

                              2(40) =80

                              80 =80

If EG = 2u + 9 and EI = 5u - 48, find EI in parallelogram FGHI.
zalisa [80]

Answer:

47

Step-by-step explanation:

The diagonals of a parallelogram bisect in their middle point, so :

2u + 9 = 5u - 48

3u = 57

u = 19

EI = 5* 19 - 48 = 47
