Answer:

The statement is slope of WX and YW are opposite reciprocals

Step-by-step explanation:

Given the graph in which triangle is shown

we have to choose the statement that verifies that triangle WXY is a right triangle.

Coordinates of W, X and Y are

W=(-2,3)

X=(2,1.4)

Y=(-4,-2)

To verify the triangle WXY a right triangle, we have to find the slope of these lines

\text{Slope of line joining the points }(x_1,y_1), (x_2, y_2)\text{ is }

slope=\frac{y_2-y_1}{x_2-x_1}

\text{Slope of WX=}\frac{1.4-3}{2-(-2)}=\frac{-2}{5}

\text{Slope of XY=}\frac{-2-1.4}{-4-2}=\frac{17}{30}

\text{Slope of YW=}\frac{-2-3}{-4-(-2)}=\frac{5}{2}

We see slope of WX and YW are opposite reciprocals that means these two lines are perpendicular which verifies that triangle WXY is a right triangle.

Hence, option 1 is correct

If the scale of a flag from the image to the actual were 1 inch = 63.75 ft, what is the scale factor? What is an equation that c
Luden [163]

Answer:

  • Scale Factor from the image to the actual= 765
  • y=765x

Step-by-step explanation:

The scale of the flag from the image to the actual were 1 inch = 63.75 ft.

Now,  1 foot = 12 inches

63.75 feet = k inches

k= 63.75 X 12 =765 inches

Therefore: 1 Inch represents 765 Inches

Scale Factor from the image to the actual= 765

If y is the length of the actual and x is the length of the image, then:

y=765x

devlian [24]

Answer:

Children: $13

Adults: $18

Step-by-step explanation:

Well for both sets we can set up the following system of equations,

\left \{ {{3a + 4c = 106} \atop {2a + 3c = 75}} \right.

So first we need to solve for a in the first equation.

3a + 4c = 106

-4c to both sides

3a = -4c + 106

Divide 3 by both sides

<u>a = -4/3c + 35 1/3</u>

Now we plug in that a for a in 2a + 3c = 75.

2(-4/3c + 35 1/3) + 3c = 75

-8/3c + 70 2/3 + 3c = 75

Combine like terms

1/3c + 70 2/3 = 75

-70 2/3 to both sides

1/3c = 4 1/3

Divide 1/3 to both sides

c = 13

Now we can plug in 13 for c in 3a + 4c = 106,

3a + 4(13) = 106

3a + 52 = 106

-52 to both sides

3a = 54

Divide 3 by both sides.

a = 18

<em>Thus,</em>

<em>an adult ticket is $18 and a children's ticket is $13.</em>

<em />

<em>Hope this helps :)</em>
