Answer:

Option C.

Step-by-step explanation:

Two trapezoids W'X'Y'Z' and WXYZ have been given in the figure attached.

Trapezoid WXYZ has been dilated to form another trapezoid W'X'Y'Z'.

We have to find the scale factor by which WXYZ was dilated.

Dilation factor = $\frac{\text{Trapezoid W'X'Y'Z'}}{\text{Trapezoid WXYZ}} = \frac{W'X'}{WX}$

= $\frac{6}{8}$

= $\frac{3}{4}$

Therefore, $\frac{3}{4}$ is the dilation factor by which trapezoid WXYZ was dilated.

Option C is the answer.

6. Write the equation of the line in slope-intercept form given the following:

Juliette [100K]

Answer:

$y=\dfrac{5}{4}x+1$

Step-by-step explanation:

Slope intercept form a equation of a line is given by the following formula:

Slope intercept form:

$y=mx+c$

Given that, a point is (-4,-4)

i.e.

$x=-4,\\y=-4$

Slope, $m =\frac{5}{4}$

Putting the given values in the Slope intercept form equation:

$-4=-4\times \dfrac{5}{4}+c\\\Rightarrow -4=-5+c\\\Rightarrow c =1$

Putting the value of $c$ and $m$ in the slope intercept form:

$y=\dfrac{5}{4}x+1$

The Natchez Trace Bridge in Franklin, Tennessee, is 1,500 feet long. Suppose you build a model of the bridge using a scale of 1

noname [10]

Set this up as a ratio putting inches on top and feet on bottom. Then your first ratio would be 1/25 since 1 inch is the same as 25 feet. In between them goes an equals sign and the the other ratio has an x on top (because inches is what we are looking for) and the 1500 on the bottom. Cross multiply to solve for x:
1(1500) = x(25). Divide both sides by 25 to get 60

Find the equation of a line that contains the points (3,7) and (-6, 4). Write the equation in slope-intercept form, using

NikAS [45]

Answer:

$y=\frac{1}{3} x+6$

Step-by-step explanation:

$(3,7)(-6,4)$

Step 1. Find the slope (by using the slope-formula)

m = slope

$m=\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{4-7}{-6-3}$

$m=\frac{-3}{-9}$

$m=\frac{3}{9}$

$m=\frac{1}{3}$

Step 2. Write the equation (using the slope and the points)

Here's how to do it:

Slope-intercept Formula $y=mx+b$ whrere m = slope and b = y-intercept

Plug in the slope into the Slope-intercept Formula

$y=\frac{1}{3} x+b$

Find the y-intercept (b) by using a point and substituting their x and y values

$y=\frac{1}{3} x+b$

Point: (3, 7)

$7=\frac{1}{3} (3)+b$

$7=1+b$

$b=7-1$

$b=6$

Step 3. Write the equation in Slope-intercept form

$y=mx+b$

$y=\frac{1}{3} x+6$
