Answer:

The solutions to the system of equations will be:

[tex]y=6,\:x=0[/tex]

Step-by-step explanation:

Given the equation

[tex]-6y+11x=-36[/tex]

[tex]-4y+7x=-24[/tex]

solving the system of equations

[tex]\begin{bmatrix}-6y+11x=-36\\ -4y+7x=-24\end{bmatrix}[/tex]

[tex]\mathrm{Multiply\:}-6y+11x=-36\mathrm{\:by\:}2\:\mathrm{:}\:\quad \:-12y+22x=-72[/tex]

[tex]\mathrm{Multiply\:}-4y+7x=-24\mathrm{\:by\:}3\:\mathrm{:}\:\quad \:-12y+21x=-72[/tex]

[tex]\begin{bmatrix}-12y+22x=-72\\ -12y+21x=-72\end{bmatrix}[/tex]

[tex]-12y+21x=-72[/tex]

[tex]-[/tex]

[tex]\underline{-12y+22x=-72}[/tex]

[tex]-x=0[/tex]

[tex]\begin{bmatrix}-12y+22x=-72\\ -x=0\end{bmatrix}[/tex]

solving for x

[tex]-x=0[/tex]

[tex]\mathrm{Divide\:both\:sides\:by\:}-1[/tex]

[tex]\frac{-x}{-1}=\frac{0}{-1}[/tex]

[tex]x=0[/tex]

[tex]\mathrm{For\:}-12y+22x=-72\mathrm{\:plug\:in\:}x=0[/tex]

[tex]-12y+22\cdot \:0=-72[/tex]

[tex]-12y+0=-72[/tex]

[tex]-12y=-72[/tex]

[tex]\mathrm{Divide\:both\:sides\:by\:}-12[/tex]

[tex]\frac{-12y}{-12}=\frac{-72}{-12}[/tex]

[tex]y=6[/tex]

Therefore, the solutions to the system of equations will be:

[tex]y=6,\:x=0[/tex]

F. Square root of 39

Step-by-step explanation:

Value of [tex]\boldsymbol{x}[/tex] is [tex]\boldsymbol{\sqrt{39}}[/tex] units.

Option F. is correct.

Two triangles are said to be similar if their sides are proportional and their corresponding angles are equal.

[tex]\bigtriangleup ABD \sim \bigtriangleup CAD[/tex]

[tex]\boldsymbol{\frac{AD}{CD}=\frac{BD}{AD} }[/tex]

  [tex]\frac{x}{13}=\frac{3}{x}[/tex]

  [tex]x^2=39[/tex]

   [tex]x=\sqrt{39}[/tex] units.

Value of [tex]\boldsymbol{x}[/tex] is [tex]\boldsymbol{\sqrt{39}}[/tex] units.

Option F. is correct.

Answer:

^{3} + 3x

Step-by-step explanation:

^{3} means x cubed.

Answer:

10x + 2.

Step-by-step explanation:

Perimeter = 2*2x + 2 *(3x + 1)

= 4x + 6x + 2

= 10x + 2.

Answer:

Step-by-step explanation:

a)  

4x - 3 = 2x + 7

4x - 2x = 7 + 3

2x = 10

x = 10 / 2

x = 5

b)

2x + 6 = 7x - 14

6 + 14 = 7x - 2x

20 = 5x

x = 20 / 5

x = 4

Answer:

0.0576 ft2

Step-by-step explanation:

If the scale factor between a front door's blueprint and the actual front door is 0,04 The front door's actual area is 36 ft2, while its area on the blueprint will be 1.44 ft².

The ratio among comparable dimensions of an object and a model with that object is known as an exponent in algebra. The replica will be larger if the scale factor is a whole number. The duplicate will be lowered if the step size is a fraction.

It is given that, the scale factor of the blueprint of a front door to the actual front door is 0.04. The area of the actual front door is 36 ft².

Scale factor =Area of the new shape ÷ Area of the original shape

0.04= Area of the front door on the blueprint÷36 ft²

Area of the front door on the blueprint=0.04×36

Area of the front door on the blueprint=1.44 ft²

Thus, if the scale factor between a front door's blueprint and the actual front door is 0,04 The front door's actual area is 36 ft2, while its area on the blueprint will be 1.44 ft².

Answer:

B and $684

Step-by-step explanation:

B, because wednesday is three days after sunday so 4 times 3 because she walks 4 more laps each day until saturday. Add the 24 laps she already walks 4(3)=12+24=36

By saturday she would've walked 48 laps, so 48 times 3 for the 3 dollars each lap. 48(3)=144 now u have to find the other days so the equation you would use is 3(24 + 4x), x for the day until saturday. 3(24+4(1))=3(28)=84,just do that for each day and then add all them together because the question asked by the end of the week, saturday, how much money so yea. 84+96+108+120+132+144=684

(honestly u could just keep adding 12 to the previous number as that's what it's increasing by.) haha rlly hope I'm not wrong on the second one. Have a nice day!

Answer:

x = 12

Step-by-step explanation:

9x - 20 - 4x = 40

Combine like terms

5x -20 = 40

Add 20 to each side

5x -20+20 = 40+20

5x = 60

Divide by 5

5x/5 = 60/5

x = 12

9x - 20 - 4x = 40

By transposition method, we get

9x - 4x = 40 + 20

By simplifying the like terms, we get

5x = 60

or, x = 60/5 = 12

The value of x is 12.

Answer:

2[tex]x^3[/tex] - 7[tex]x^2[/tex] + 8x -3

Step-by-step explanation:

To multiply a binomial (2 terms) by a trinomial (3 terms):

Multiply the first term of the binomial by the each term of the trinomial.

Multiply the second term of the binomial by each term of the trinomial.

Combine the expressions and simplify.

(2x-3)*([tex]x^2[/tex]-2x+1)

(2x * [tex]x^2[/tex]) + (2x * -2x) + (2x * 1)

(2[tex]x^3[/tex]) + (-4[tex]x^2[/tex]) + (2x)

(2x-3) * ([tex]x^2[/tex]-2x+1)

(-3 * [tex]x^2[/tex]) + (-3 * -2x) + (-3 * 1)
