can you help me find this

Answer:

D. 3

Step-by-step explanation:

The scale factor used to transform right triangle ABC into right triangle A'B'C' is the ratio of any corresponding side length of ∆A'B'C' and ∆ABC.

Thus, using the ratio of side length A'B' to side length A'B', we can get the scale factor as follows:

A'B' = 12 - 6 = 6 units

AB = 4 - 2 = 2 units

Scale factor = A'B' : AB = 6 : 2 = 6/2 = 3

Answer:

The equation 5x + y = 0  represents a direct variation

The  constant of variation is k=-5

Step-by-step explanation:

We need to tell if the equation 5x+y=0 represents a direction variation or not.

The equation for direct variation is: [tex]\mathbf{y=kx}[/tex]

where k is constant of variation.

In the given equation:

[tex]5x+y=0\\y=-5x[/tex]

Comparing it with general equation for direct variation [tex]\mathbf{y=kx}[/tex] we get [tex]y=-5x[/tex] so equation represents direct variation.

Value of k is -5

So, the  constant of variation is k=-5

Answer:

CE = 35

Step-by-step explanation:

Δ CBD and Δ CAE are similar thus ratios of corresponding sides are equal, that is

[tex]\frac{CB}{CA}[/tex] = [tex]\frac{CD}{CE}[/tex] , substitute values

[tex]\frac{x-5}{x-5+6}[/tex] = [tex]\frac{14}{14+2x + 3}[/tex] , then

[tex]\frac{x-5}{x+1}[/tex] = [tex]\frac{14}{2x +17}[/tex] ( cross- multiply )

(x - 5)(2x + 17) = 14(x + 1) ← distribute both sides

2x² + 7x - 85 = 14x + 14 ( subtract 14x + 14 from both sides )

2x² - 7x - 99 = 0 ← in standard form

(x - 9)(2x + 11) = 0 ← in factored form

quate each factor to zero and solve for x

x - 9 = 0 ⇒ x = 9

2x + 11 = 0 ⇒ 2x = - 11 ⇒ x = - [tex]\frac{11}{2}[/tex]

but x > 0 , thus x = 9

Hence

CE = 2x + 17 = 2(9) + 17 = 18 + 17 = 35

Answer:

3

Step-by-step explanation:

Answer:

5

Step-by-step explanation:

First the question said that two equal sides of the isosceles triangles is thrice the third side. This means that the two equal sides is 3x while the third side should be represented as x

Secondly, add the three parts together which = 3x+3x+x =7x

Thirdly, then divide both sides by 7= 7x/7 *35/7

Making x=5

Answer:

k = 12

Step-by-step explanation:

Given in the question,

Cost of the the movie tickets is proportional to the number of tickets sold.

Cost of movie tickets (C) ∝ number of tickets sold (T)

C ∝ T

C = kT

Here 'k' is a proportionality constant.

Since, line given in the graph passes through a point (5, 60)

60 = k(5)

k = [tex]\frac{60}{5}[/tex]

k = 12

Therefore, value of proportionality constant is 12.

B is the answer

Step-by-step explanation:

you are given two points (0,6) and (2,1)

the equation is y=mx+b it says that the graph has a y-intercept (0,6) from this point you take the y-value which is also ur b-value in the equation to find m you need to do y2-y1/x2-x1

Answer:

Step-by-step explanation:

Segment BD is a leg of the right triangles. It is congruent to itself (whether or not it is marked). Angles A and C are corresponding acute angles in the right triangles. They are marked as congruent to each other.

The triangles are congruent by the LA theorem, applicable to right triangles. The congruency statement can be written as ...

Answer in short, 1.32 x 10^5 is your answer.

Step-by-step explanation:

Take the first number, or 136000 and subtract it by 4000 (the second number.

Answer:

[tex]1.32*10^5[/tex]

Answer: 3/2

Step-by-step explanation:

The first one: y=2x+5

X=2y+5.Then solve for y after switching x and y

X-5=2y, X-5/2=y

Since F-1= X-5/ 2, we plug the value of X in

8-5/2, so it should be 3/2

Step-by-step explanation:

you would do 5-2=3 ,

5/3

and then multiply by 100

Answer:

We have the equations:

1.15x + 0.65y = 8.90

and

x − 3y = -15

First, let's write them in the slope-intercept form:

The first one will be:

y = -(1.15/0.65)*x + 8.90/0.65  

The second:

y = (1/3)*x + 15/3 = (1/3)*x + 5.

then our system is:

y = -(1.15/0.65)*x + 8.90/0.65  

y  = (1/3)*x + 5.

To graph each line, you can just evaluate the line in two points (for x = 0 and x = 1, for example) and then locate those points in the coordinate axis, and then draw a line that connects them.

For example with the second line:

y(0) = (1/3)*0 + 5 = 5

then we have the point (0,5)

and

y(3) = (1/3)*3 + 5 = 8

Then we have the point (3,8)

With the first equation may be a little harder, as the coefficients are not whole numbers, we can rewrite it as:

y = (1.15/0.65)*x + 8.90/0.65  = (115/65)*x + (890/65)

Where i multiplied and divided by 100 the numerators and denominators in the right side, so now is easier to work with it.

The points you can use are:

y(0) =  (115/65)*0 + (890/65) = 13.7

the point is (0, 13.7)

and:

y(1) = (115/65)*1 + (890/65) = 15.5

The point is (1, 15.5)

Below you can see the graphs of both functions:

blue: y = -(1.15/0.65)*x + 8.90/0.65

red: y  = (1/3)*x + 5

The answer is in the picture below!
