The formula of a midpoint:

\left(\dfrac{x_1+x_2}{2};\ \dfrac{y_1+y_2}{2}\right)

D is midpoint of TR.

We have T(-2a, 0) and R(-2b, 2c). Substitute:

x=\dfrac{-2a+(-2b)}{2}=\dfrac{-2a-2b}{2}=\dfrac{2(-a-b)}{2}=-a-b\\\\y=\dfrac{0+2c}{2}=\dfrac{2C}{2}=c

<h3>Answer: b.  (-a - b, c)</h3>

The graph of f(x) =sqrt of x is reflected across the x-axis and then across the y-axis to create the graph of function g(x). Whi
pickupchik [31]

The original function is

f(x)=√x

As this is condition for √x function, x≥ 0

So,

Domain= [0, infinity)

Range= [0, infinity)


After the reflection across x-axis and y-axis, we get a function,

g(x)=-√-x

-x≥ 0 means x≤ 0,

So,

Domain= (-infinity, 0]

Range= (-infinity, 0]


From this you can see that

-The only value that is in the domains of both functions is 0.

-The range of g(x) is all values less than or equal to 0.


only these points are correct and all other points are wrong.


See the attached graphs for both functions.

Sam's truck weighs 4725 lb the truck can carry 7500 lb what is the total weight of the truck and full load
MA_775_DIABLO [31]
Since we need to find the final weight, we simply need to add the weight of the truck and the load.

4725 + 7500 = 12225

Your final answer should be 12225 pounds. Hope this helps!

The measure of an inscribed angle in a circle is ______ the measure of the intercepted arc.
xxMikexx [17]

C. Half

<u>Explanation:</u>

An inscribed angle is an angle with its vertex on the circle and whose sides are chords. The intercepted arc is the arc that is inside the inscribed angle and whose endpoints are on the angle.

The Inscribed Angle Theorem states that the measure of an inscribed angle is half the measure of its intercepted arc.

Inscribed angles that intercept the same arc are congruent.
