Answer:

CD = 25 ft

Step-by-step explanation:

[tex] \triangle CDE \sim \triangle RST[/tex]

[tex]\therefore \frac{CD}{20}=\frac{40}{32}[/tex]

(Corresponding sides of similar triangles are in proportion)

[tex]\therefore \frac{CD}{20}=\frac{5}{4}[/tex]

[tex]\therefore CD = \frac{5}{\cancel 4}\times \cancel {20} \:\:\blue{\bold{5}} [/tex]

[tex]\therefore CD = 5\times 5[/tex]

[tex]\therefore CD = 25\: ft[/tex]

Answer:

CD = 25 ft

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{CD}{RS}[/tex] = [tex]\frac{CE}{RT}[/tex] , substitute values

[tex]\frac{CD}{20}[/tex] = [tex]\frac{40}{32}[/tex]  ( cross- multiply )

32CD = 800 ( divide both sides by 32 )

CD = 25

Answer:

Step-by-step explanation:

set jk and kl equal to each other bc they are the same length (we know this bc of the midpoint)

3x - 1 = 2x + 8

x = 9

substitute 9 in an equation

2(9) = 8 = KL

18 + 8

26 = KL

since KL is the same length as JK we can just multiply 26 * 2

JL = 52

Answer:

[tex]-\frac{8}{x-a}[/tex]

Step-by-step explanation:

[tex]\frac{8}{a-x}[/tex]

we can take common factor of -1 in the denominator

[tex]\frac{8}{-(-a+x)}=\frac{8}{-(x-a)}[/tex]

and now multiply and divide by -1

[tex]\frac{8}{-(x-a)}\cdot \frac{-1}{-1}=\frac{-8}{x-a}=-\frac{8}{x-a}[/tex]

Answer:

The equation of perpendicular bisector of the line segment passing through  (-5,3) and (3,7) is: [tex]y = -2x+3[/tex]

Step-by-step explanation:

Given points are:

(-5,3) and (3,7)

The perpendicular bisector of line segment formed by given points will pass through the mid-point of the line segment.

First of all we have to find the slope and mid-point of given line

Here

(x1,y1) = (-5,3)

(x2,y2) = (3,7)

The slope will be:

[tex]m = \frac{y_2-y_1}{x_2-x_1}\\m = \frac{7-3}{3+5}\\m = \frac{4}{8}\\m = \frac{1}{2}[/tex]

The mid-point will be:

[tex](x,y) = (\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2})\\ = (\frac{-5+3}{2},\frac{3+7}{2})\\= (\frac{-2}{2},\frac{10}{2})\\=(-1,5)[/tex]

Let m1 be the slope of the perpendicular bisector

Then using, "Product of slopes of perpendicular lines is -1"

[tex]m.m_1 = -1\\\frac{1}{2}.m_1 = -1\\m_1 = -1*2\\m_1 = -2[/tex]

We have to find the equation of a line with slope -2 and passing through (-1,5)

The slope-intercept form is given by:

[tex]y = mx+b\\y = -2x+b[/tex]

Putting the point (-1,5) in the equation

[tex]5 = -2(-1)+b\\5 = 2+b\\b = 5-2\\b = 3[/tex]

The final equation is:

[tex]y = -2x+3[/tex]

Hence,

The equation of perpendicular bisector of the line segment passing through  (-5,3) and (3,7) is: [tex]y = -2x+3[/tex]

Step-by-step explanation:

Domain of a graph or function is defined by the x-values (Input values).

From the graph attached,

Since, the graph starts from x = -5 and ends at x = 11,

(Shown as the dark points)

Therefore, domain of the graph will be represented by,

Answer:

Step-by-step explanation:

The number of Jefferson students and the number of non-Jefferson students if A student attending Jefferson pays $5, A student attending a different school pays $10 is 373 and 127 respectively.

Equation: A declaration that two expressions with variables or integers are equal. In essence, equations are questions and attempts to systematically identify the solutions to these questions have been the driving forces behind the creation of mathematics.

Given:

A student attending Jefferson pays $5,

A student attending a different school pays $10,

The total number of tickets = 500,

The total money earned = $3135,

Write the equation of the given statement as shown below,

x + y = 500

5x + 10y = 3135

Here, x is the number of Jefferson students and y is the number of non-Jefferson students,

Solve the equation by elimination method as shown below,

y = 127,

x = 500 - 127 = 373

Thus, the number of Jefferson students is 373 and the number of non-Jefferson students is 127.

Step-by-step explanation:

Answer:

its (c) and (d)

Step-by-step explanation:

Answer:

5x + 2y = 7

3x � y = 2

multiply the second equation by 2 and leave the first equation as is to get:

5x + 2y = 7

6x � 2y = 4

add the second equation to the first equation to get:

11x = 11

divide both sides of that equation by 11 to get:

x = 1

replace x with 11 in the first original equation to get:

5x + 2y = 7 becomes 5 + 2y = 7

solve for y to get y = 1

your solution is x = 1 and y = 1

confirm by replacing x and y with 1 and 1 in both original equations to get:

5x + 2y = 7 becomes 5 + 2 = 7 which is true.

3x � y = 2 becomes 3 - 1 = 2 which is true.

Step-by-step explanation:

Given a system of two equations in two variables, replacing one equation by the sum of that equation and a multiple of the other produces a system with the same solution. Show why this is true by solving the system of equations given. Justify the reason for each step. HINT: Use addition property of equality and multiplication property of equality in your answers.

5x + 2y = 7

3x � y = 2
