Are the two triangles in the figure Similar? Justify the answer.what is the distance d across the lake?
Delicious77 [7]

Two triangles are Similar if the only difference is size (and possibly the need to turn or flip one around). Therefore would be answer B.

Find the ratio

\begin{gathered} \frac{80}{30}=\frac{d}{180} \\ d=180\cdot\frac{80}{30} \\ d=480\text{ ft} \end{gathered}

The distance would be 480 ft

How do you graph the inequality of 4x-2y≤6 ?
Orlov [11]

4x - 2y ≤ 6      <em>subtract 4x from both sides</em>

-2y ≤ -4x + 6     <em>change the signs</em>

2y ≥ 4x - 6     <em>divide both sides by 2</em>

<h3>y ≥ 2x - 3</h3>

y = 2x - 3 - it's a linear function. We need only two points to plot the graph.

Choose any two values of x and calculate the values of y:

for x = 0 → y = 2(0) - 3 = 0 - 3 = -3 → (0, -3)

for x = 2 → y = 2(2) - 3 = 4 - 3 = 1 → (2, 1)
