Answer:

$- 39xy + 12 {y}^{2}$

Step-by-step explanation:

1) Simplify 6x × 2y to to 12xy.

$12xy - 3xy - 24xy \times 2 + 12 {y}^{2}$

2) Simplify 24xy × 2 to 48xy.

$12xy - 3xy - 48xy + 12 {y}^{2}$

3) Collect like terms.

$(12xy - 3xy - 48xy) + 12 {y}^{2}$

4) Simplify.

$- 39xy + 12 {y}^{2}$

<u>Thus</u><u>,</u><u> </u><u>The</u><u> </u><u>answer</u><u> </u><u>is</u><u> </u><u>-39xy</u><u> </u><u>+</u><u> </u><u>12y</u><u>²</u>.

Y = 7x + 7<br> y = -7x + 19<br><br> Solve the system algebraically.

shtirl [24]

Hello,

To this question, It's only directly sum the equations:

y + y = 7x - 7x +7+19

2y = 0x + 26

2y = 26

y = 26 ÷ 2

y = 13

Now only to replace y = 13 in the equation of up or of down.

Then stay:

y = 7x + 7

13 = 7x + 7

7x = 13 -7

7x = 6

x = 6 / 7

Suppose a home improvement contractor is painting the walls and ceiling of a rectangular room. The volume of the room is 288 cub

ratelena [41]

Answer:

The minimum cost is $17.30c

Step-by-step explanation:

Given

$V = 288$ --- Volume

$C_1 = 0.06$ --- cost of wall paint

$C_2 = 0.16$ ---cost of ceiling paint

Required

Minimum cost of paint

The volume is calculated as:

$V =xyz$

Substitute 288 for V

$288 =xyz$

Make z the subject

$z = \frac{288}{xy}$

The surface area is calculated as:

$Area = 2(yz + xz) + xy$

Because xy represent the dimension of the ceiling and the opposite of the ceiling (the floor) will not be painted. Hence, it does not require a coefficient of 2

The cost is:

$C = 0.06 * 2(yz + xz) + 0.16 * xy$

Substitute $z = \frac{288}{xy}$

$C = 0.06 * 2(y*\frac{288}{xy} + x*\frac{288}{xy}) + 0.16 * xy$

$C = 0.06 * 2(\frac{288}{x} + \frac{288}{y}) + 0.16 * xy$

$C = 0.12(\frac{288}{x} + \frac{288}{y}) + 0.16 * xy$

$C = (\frac{34.56}{x} + \frac{34.56}{y}) + 0.16 * xy$

$C = (\frac{34.56}{x} + \frac{34.56}{y}) + 0.16 xy$

Differentiate w.r.t x and y

$C_x = -\frac{34.56}{x^2} + 0.16y$

$C_y = -\frac{34.56}{y^2} + 0.16x$

By comparison: $x = y$

Set them equal to 0

$C_y = -\frac{34.56}{y^2} + 0.16x=0$

$-\frac{34.56}{y^2} + 0.16x=0\\$

Substitute x for y

$-\frac{34.56}{x^2} + 0.16x=0$

$0.16x=\frac{34.56}{x^2}$

Cross multiply

$0.16x^3 = 34.56$

$x^3 = \frac{34.56}{0.16}$

$x^3 = 216$

Take the cube root of both sides

$x = \sqrt[3]{216}$

$x = 6$

$x=y= 6$

Substitute 6 for x and for y in $C = (\frac{34.56}{x} + \frac{34.56}{y}) + 0.16 xy$

$C = (\frac{34.56}{6} + \frac{34.56}{6}) + 0.16 * 6* 6$

$C = (\frac{2*34.56}{6}) + 5.76$

$C = 11.52 + 5.76$

$C = 17.28$

$C = 17.3$ --- approximated
