Answer:

x = 3.76 ft

Step-by-step explanation:

To find the missing side, "x", solve using proportions.

In similar polygons, the 'new' polygon was created by multiplying every side of the 'old' polygon by the same number. Every side was multiply by the scale factor, "k", which tells you how much a polygon grew (k>1) or shrunk (0<k<1).

Therefore, if you divided the pairs of corresponding sides, they would be equal.

From the diagram, you can tell that the following sides correspond:

CB ~ GF

AB ~ EF

Use the proportion

$\frac{EF}{AB} = \frac{GF}{CB}$

$\frac{x}{6ft} = \frac{3.3ft}{5ft}$ Substitute values from diagram

$6ft*\frac{x}{6ft} = 6ft*\frac{3.3ft}{5ft}$ Multiply both sides by 6 ft

$x = \frac{6ft*3.3ft}{5ft}$ "x" is isolated. Multiply fraction by combining into numerator

$x = \frac{19.8ft}{5ft}$ Solved numerator. Divide for decimal answer.

$x = 3.76ft$

The value of 'x' is 3.76 ft.

Graph the linear equation x-3y=-6

TEA [102]

Answer:

Step-by-step explanation:

One of the easier approaches to graphing a linear equation such as this one is to solve it for y, which gives us both the slope of the line and the y-intercept.

x-3y=-6 → -3y = -x - 6, or 3y = x + 6.

Dividing both sides by 3, we get y = (1/3)x + 2.

So the slope of this line is 1/3 and the y-intercept is 2.

Plot a dot at (0, 2). This is the y-intercept. Now move your pencil point from that dot 3 spaces to the right and then 1 space up. Draw a line thru these two dots. End.

Alternatively, you could use the intercept method. We have already found that the y-intercept is (0, 2). To find the x-intercept, let y = 0. Then x = -6, and the x-intercept is (-6, 0).

Plot both (0, 2) and (-6, 0) and draw a line thru these points. Same graph.
