Step-by-step explanation:

First of all, if the system of equations has exactly one solution, then the graph of these two equations will intersect at exactly one point, which means their slopes will be different. If the slopes are the same, there could be infinitely many solutions or no solution.

Rearrange the first equation to solve for slope of  [tex]-2x+ky=26[/tex]

y = (2/k)x + 26/k

The slope is 2/k.

The slope of the second equation is 13/6

as long as 2/k does not equal to 13/6, we have exactly one solution.

SO, the last step:

[tex]\dfrac{2}{k} \neq \dfrac{13}{6}\\[/tex]

[tex]k \neq \dfrac{2}{\dfrac{13}{6}}[/tex]

[tex]k\neq \dfrac{12}{13}[/tex]

Step-by-step explanation:

irst note that 6/8=6/8=9/12, which shows that these are similar triangles. Any of these fractions is the ratio of corresponding sides. Reduce it and find the denominator

Two triangles are known to be similar if the ratio of the similar sides and angles are equal. The value of n, if the two triangles are similar is 3.75

Two triangles are known to be similar if the ratio of the similar sides and angles are equal.

From the given triangles, we have the following

Scale factor  = 3/n

Determine the ratio of the sides

Ratio = 12/15 = 3/n

Cross multiply

12n = 15 * 3
12n = 45

n = 3.75

Hence the value of n, if the two triangles are similar is 3.75

for a ratonal, the expression only makes sense if the denominator is not 0, since if that occurs then the expression becomes undefined, a division by 0 is always undefined, for this case, when does that occur?  Let's set the denominator to 0 and solve for "x".

[tex]\cfrac{\sqrt{2}}{\sqrt{x-1}} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{setting the denominator to 0}}{\sqrt{x-1}=0\implies (\sqrt{x-1})^2=0^2}\implies x-1=0\implies x=1[/tex]

well then, let's see what happens when x = 1

[tex]\cfrac{\sqrt{2}}{\sqrt{x-1}}\implies \cfrac{\sqrt{2(1)}}{\sqrt{1-1}}\implies \cfrac{\sqrt{2}}{\sqrt{0}}\implies \cfrac{\sqrt{2}}{0}\leftarrow und efined[/tex]

so the only values that makes sense is anything but x < 1, because a smaller value of 1 will give us an imaginary value from the root, so the only values that makes sense are namely { x | x ∈ ℝ; x > 1 }

Answer:

Graphs of reciprocal functions reflect against their original functions. For example, y=arcsinx reflects against y=sinx. To graph trigonomoetric functions, simply use a graphing calculator, like Desmos. It's easy. go to Desmos and type y=sinx. It will make a graph for you. Then on a line below the function, type y=arcsinx. You will notice how the inverse of sine reflects against sine. I would teach a visual person by not saying as much and just writing out the equations and using Desmos. To an auditory person, I'd explain as I do the math. I don't know what some of these words mean, but if someone wants a physical example, I'd give them a realistic world problem. I'd ask them to stand up and imagine they are this many feet away from an object that is this many feet tall. We will set up a realistic equation together.

Answer:

Step-by-step explanation:

even (2, 4, 6, 8, 10, 12) = 6/12 = 1/2

cube (1, 8) = 2/12 = 1/6     (although all numbers are a cube of something, just not a whole, or even rational, number)

prime (1, 2, 3, 5, 7, 11) = 6/12 = 1/2

odd (1, 3, 5, 7, 9, 11) = 6/12 = 1/2

Answer:

1.5 or 1 1/2

Step-by-step explanation:

2x+7=10 (subtract 7 from both sides)

2x=10-7

2x=3 (divide both sides by 2)

X=3/2  

Simplify

X= 1.5 or 1 1/2

B.)y+1= -1(x+10)

Step-by-step explanation:

y+1= -1(x+10) so the correct choice would be B.

Answer:

B. y + 1 = -(x + 10)

Step-by-step explanation:

Use the given slope and point to substitute into the point-slope formula  y − y 1 = m ( x − x 1 ) .

Slope-intercept form:  y = − x − 11

Point-slope form:  y + 1 = − 1 ⋅ ( x + 10 )

Answer:

m∠ABD = 24°, m∠CBD = 24°, m∠ABC = 48°

Step-by-step explanation:

3x+6=7x-18

3x-7x=-18-6

   -4x=-24

      x=24÷4

        =6

Hence, ∠ABD = (3x+6)°

                       = [3(6)+6]°

                       = (18+6)°

                       = 24°

Hence, ∠CBD = 24°

Hence, ∠ABC = 24°×2

                       = 48°

Answer:

Step-by-step explanation:

The distributive property tells you the factor outside parentheses multiplies each of the terms inside parentheses.

The difference 6 -3 inside parentheses has two terms, and there is a factor of 5 outside those parentheses. The setup for the distributive property is there, so the distributive property can be used.

__

The outside factor multiplies each inside term. The sign can be left with the inside term, or can be placed between the products.

  5 × (6 - 3) = (5×6) - (5×3)

__

or

  5 × (6 - 3) = (5×6) +(5×(-3))

Step-by-step explanation:

[tex] = 47.000[/tex]

[tex] = 4,7 \times 10.000 [/tex]

[tex] = 4,7 \times {10}^{1+1+1+1} [/tex]

[tex] = 4,7 \times 10^4 [/tex]

Answer:

no

Step-by-step explanation:

a) The function that is parallel to the function [tex]y = 0.5\cdot x + 10[/tex] and intercept the function [tex]y = -1.5\cdot x[/tex] is [tex]y = 0.5\cdot x - 6[/tex].

b) The functions that are parallel to the function [tex]y = 0.5\cdot x + 10[/tex] and intercept the function [tex]y = -1.5\cdot x[/tex]  are [tex]y = 0.5\cdot x + 4[/tex] and [tex]y = 0.5\cdot x[/tex].

Linear functions are expressions of the following form:

[tex]y = m\cdot x + b[/tex] (1)

Where:

Two lines are parallel if and only if they have the same slope but distinct intercepts. and two lines intercept each other when they have distinct slopes. Now we proceed to present the solution for each point:

a) The function that is parallel to the function [tex]y = 0.5\cdot x + 10[/tex] and intercept the function [tex]y = -1.5\cdot x[/tex] is [tex]y = 0.5\cdot x - 6[/tex].

b) The functions that are parallel to the function [tex]y = 0.5\cdot x + 10[/tex] and intercept the function [tex]y = -1.5\cdot x[/tex]  are [tex]y = 0.5\cdot x + 4[/tex] and [tex]y = 0.5\cdot x[/tex].
