Answer:

(23/27, 11/9)

Step-by-step explanation:

Given the simultaneous equation;

-6x+5y=1..... 1

6x+4y=10.... 2

Add both equations

5y + 4y = 1+10

9y = 11

y = 11/9

Substitute y = 11/9 into 1;

From 1;

-6x+5y=1.

-6x + 5(11/9) = 1

-6x + 55/9 = 1

-6x = 1- 55/9

-6x = (9-55)/9

-6x = -46/9

x = -46/-54

x = 23/27

The solution to the system of equation is (23/27, 11/9)

Step-by-step explanation:

u multiply one length by it widgth so 48 x 48

Answer:

144 m

Step-by-step explanation:

Here , The perimeter of a square=48 m.

Area=?

Since,each side of a square= perimeter/4

=48/4

=12m.

Hence, the area of the square=(side)²

=(12)².

=144 m² Ans.

Answer:

846.06 units

Step-by-step explanation:

The amount of profit, y, made by the  company, is related to the selling price of each widget, x, by the given  equation as follows :

[tex]y = -4x^2 + 183x- 1247[/tex] ...(1)

We need to find out the maximum amount of profit  the company can make.

For maximum profit put dy/dx = 0

So,

[tex]\dfrac{d}{dx}(-4x^2 + 183x- 1247)=0\\\\-8x+183=0\\\\x=\dfrac{183}{8}\\\\x=22.87[/tex]

Put x = 22.87 in equation (1). So,

[tex]y = -4(22.87)^2 + 183(22.87)- 1247\\\\=846.06[/tex]

So, the maximum profit is 846.06 units.

In set theory, De Morgan's Laws relate the intersection and union of sets through complements. In propositional logic, De Morgan's Laws relate conjunctions and disjunctions of propositions through negation. De Morgan's Laws are also applicable in computer engineering for developing logic gates.

Answer:

CE= 32

QS= 14

Step-by-step explanation:

Since the C=R and the E=Q, and the RQ is 16, the CE is 2x that value. (Since the CDE is 2x bigger than RSQ)

You also want to flip the triangles until they are in the same positions as each other so you can analyze it easier

Answer:

Some examples

Step-by-step explanation:

1.The vertices of triangle ABC are A(2,-3), B(-3,-5), and C(4,1). For each translation, give the vertices of triangle A'B'C'. When the transformation (-2,3). When the T (-4,-1) and T

C

2.Triangle ABC has vertices A(-3,0) B(0,6) C(4,6). Find the equations of the three medians of triangle ABC

Triangle ABC has vertices A(-3,0) B(0,6) C(4,6). Find the equations of the three altitudes of the same triangle

Triangle ABC has vertices A(-3,0) B(0,6) C(4,6). Find the equations of the three perpendicular bisectors of the same triangle.

A(−3, 0), B(0, 6), and C(4, 6)

using the midpoint formula:  we can find all of their midpoint which is necessary to complete question 1 and 2

Mid AB=(-1.5, 3), Mid BC=(2, 6), Mid AC=(0.5,3)

Next, we have to find the slope of from the vertex and the midpoint of each side. We use the slope formula: .

You would get -6, 6/5, and 6/11.

Next you substitute in the coordinates for the equation of each for example: y=-6x, you switch in the set of cords AB which is (-1.5, 3). 3=-6(-1.5)+z and find that z=6, so the equation is y=-6x+6. As for the rest, repeat the same process until you find all 3 cords. You should get an answer of

For question 2,

The line has to be perpendicular bisector to the midpoint, signifying that it has to split 2 angles into congruent angles and a side into half. In order to do that we need to first find the opposite reciprocal of each side's slope. Which means we need to once again use the slope formula and get the opposite reciprocal by . For all the opposite reciprocal slopes you get will be incorporated into the final formulas. That gives us the slopes of -1/2, 0 and -7/6.

I hope this helps! :)

Answer:

V = 6x^3 - 9x^2 - 6x (which matches the third answer choice)

Step-by-step explanation:

The volume of a rectangular prism of length L, depth W and height H is

V = L * W * H.

Thus,

in this case,

V = (2x + 1)(x - 2)(3x).

The order in which we multiply these quantities together is immaterial.

Working from left to right, we get:

V = (2x^2 - 3x - 2)(3x), and then:

V = 6x^3 - 9x^2 - 6x (which matches the third answer choice)

Answer:

7.9

Step-by-step explanation:

y2-y1\x2-x1

Answer:

DC = 3

Step-by-step explanation:

Based on triangle similarity theorem, we would have the following equation:

[tex] \frac{AD}{AC} = \frac{AE}{AB} [/tex]

Plug in the values

[tex] \frac{9}{9 + DC} = \frac{12}{12 + 4} [/tex]

[tex] \frac{9}{9 + DC} = \frac{12}{16} [/tex]

[tex] \frac{9}{9 + DC} = \frac{3}{4} [/tex]

Cross multiply

3(9 + DC) = 9×4

27 + 3DC = 36

Subtract 27 from each side

3DC = 36 - 27

3DC = 9

Divide both sides by 3

DC = 9/3

DC = 3

[tex] - 12 - 3y \geq - 6x \\ - 12 - 3y + 12 \geq - 6x + 12 \\ - 3y \geq - 6x + 12 \\ = \frac{ - 3y}{ - 3} \geq \frac{ - 6x + 12 }{ - 3} \\ y = 2x - 4 [/tex]

Correct me if I'm wrong

Answer:

can i see the rest of it

Step-by-step explanation:

Answer:

Step-by-step explanation:

Example 1:

Evaluate the following expression:

4 + (3x +y)

When x = 2 and y = 9

3 x 2 is 6 after that you just add 6+9+4 which is 19

Example 2:

Evaluate the expression when x=8 and y=9

x(y - 9)^3 + 2

=8(9-9)^3+2

=8(0)^3+2

=8(0)+2

=0+2

=0

Answer:

(d) They may be combines

Step-by-step explanation:

Given

[tex]6\sqrt{32} - 12\sqrt{72}[/tex]

Required

Which option is true

Express 32 as 16 * 2 and 72 as 36 * 2

[tex]6\sqrt{32} - 12\sqrt{72} = 6\sqrt{16 * 2} - 12\sqrt{36 * 2}[/tex]

Split

[tex]6\sqrt{32} - 12\sqrt{72} = 6\sqrt{16} * \sqrt{2} - 12\sqrt{36} * \sqrt{2}[/tex]

This gives:

[tex]6\sqrt{32} - 12\sqrt{72} = 6*4 * \sqrt{2} - 12*6 * \sqrt{2}[/tex]

[tex]6\sqrt{32} - 12\sqrt{72} = 24 * \sqrt{2} - 72 * \sqrt{2}[/tex]

[tex]6\sqrt{32} - 12\sqrt{72} = 24 \sqrt{2} - 72 \sqrt{2}[/tex]

Since both term have the same radicand, then:

[tex]6\sqrt{32} - 12\sqrt{72} =( 24 - 72 )\sqrt{2}[/tex]

[tex]6\sqrt{32} - 12\sqrt{72} =-48\sqrt{2}[/tex]

Option (d) is correct
