Make Y the subject of 3(y+2x-1)=x+5y

LekaFEV [45]

Answer:

y = $\frac{5x-3}{2}$

Step-by-step explanation:

Given

3(y + 2x - 1) = x + 5y ← distribute left side

3y + 6x - 3 = x + 5y ( subtract 5y from both sides )

- 2y + 6x - 3 = x ( subtract 6x - 3 from both sides )

- 2y = - 5x + 3 ( multiply through by - 1 )

2y = 5x - 3 ( divide both sides by 2 )

y = $\frac{5x-3}{2}$

The perimeter of a rectangle is 40 inches. The table shows some of the possible dimensions for the length and area of the rectan

Mama L [17]

Answer:

Therefore the Dimensions are

Length =18 inches and Width = 2 inches

OR

Length =2 inches and Width = 18 inches

Step-by-step explanation:

Let the Width of rectangle be 'W' inches.

The length of a rectangle be 'L' inches.

Area of rectangle given is 36 square inches.

Perimeter of Rectangle is 40 inches.

To Find:

Length = L = ?

Width = W = ?

Solution:

Perimeter of Rectangle is given as

$\textrm{Perimeter of Rectangle}=2\times (Length +Width)$

Substituting we get

$40=2(L+W)\\\\L+W=20\\\therefore L=20-W$

We have area of rectangle given as

$\textrm{Area of Rectangle}=Length\times Width)$

Substituting the given values we get

$36=(20-W)\times W\\W^{2}-20W+36=0$

Which is a Quadratic Equation, So by Splitting the middle term we get

$W^{2}-18W-2W+36=0\\W(W-18)-2(W-18)=0\\(W-2)(W-18)=0\\\therefore W=2\ inches\ or\ W =18\ inches$

Therefore the Length will be

$L=20-W=20-2=18\ inches\\OR\\L=20-18=2\ inches$

Therefore the Dimensions are

Length =18 inches and Width = 2 inches

OR

Length =2 inches and Width = 18 inches

-x + y = 5

diamong [38]

Answer:

A. -(5y+2) + y = 5

Step-by-step explanation:

Solving the above Equation given to us in the Question,

-x + y = 5...... Equation 1

x - 5y = 2....... Equation 2

Step 1

We make x subject of the formula in Equation 2

---> x= 5y + 2

Step 2

This would be to substitute 5y + 2 for x in Equation 1

-x + y = 5...... Equation 1

-(5y+2) + y = 5

Hence, Option A is the correct option

The light intensity I (in lumens) at a depth of x feet in Lake Elizabeth is given by the formula log (StartFraction Upper I Ove

antiseptic1488 [7]

Answer:

The light intensity at a depth of 24 feet is 3.0143 lumens.

The light intensity will be 7 lumenus at the depth of 9.3732 feet approximately.

Step-by-step explanation:

Consider the provided formula.

$log(\frac{I}{12})=-0.025x$

Where I is the intensity of light and x is the depth.

Part (A) Find the light intensity at a depth of 24 feet.

Substitute x=24 in above formula.

$log(\frac{I}{12})=-0.025(24)$

$log(\frac{I}{12})=-0.6$

$\frac{I}{12}=10^{-0.6}$

$\frac{I}{12}=0.2512$

$I=3.0143$

Hence, the light intensity at a depth of 24 feet is 3.0143 lumens.

Part (B) At what depth is the light intensity 7 lumens

Substitute I=7 in above formula.

$log(\frac{7}{12})=-0.025x$

$-0.23433=-0.025x$

$0.23433=0.025x$

$x=\frac{0.23433}{0.025}$

$x=9.3732$

Hence, the light intensity will be 7 lumenus at the depth of 9.3732 feet approximately.
