In the diagram below segment DEF is shown(since all three letters are shown, they are collinear). If DE=3x+2, EF= x+5, and DF= 2

The value of $x$ is 4.

By Geometry, we know that line segment $DF = DE + EF$ , which is equivalent to:

$DF = 3\cdot x + 2 + x + 5$

$DF = 4\cdot x + 7$ (1)

Now we solve algebraically the resulting expression.

If we know that $DF = 23$ , then we solve the equation for $x$ :

$4\cdot x + 7 = 23$

$4\cdot x = 16$

$x = 4$

The value of $x$ is 4.

A peregrine falcon can fly 322 kilometers per hour.how many meters per hour can the falcon fly

vivado [14]

The falcon can fly 322,000 meters per hour.

1 kilometer is 1000 meters, meaning you would multiply 322 by 1000 equaling 322,000.

Write the coordinates of the vertices after a translation 4 units right and 4 units down.

m_a_m_a [10]

Answer:

T'(1, -2)
U'(1, -1)
V'(2, -1)
W'(2,-2)

Step-by-step explanation:

Translation 4 right adds 4 to each x-coordinate.

Translation 4 down subtracts 4 from each y-coordinate.

Doing this arithmetic gives you the results above.
