Answer:

(-4, -1/2)

Step-by-step explanation:

to calculate the midpoints bt of the line use the ormula:

( \frac{x1 + x2}{2} \frac{y1 + y2}{2} )

Where (x1, x2) is one coordinate point and (y1, y2) is anither coordinate point. Any two points will work, but I chose A (-5,-4) and B (-3, 3).

( \frac{ - 5 + ( - 3)}{2}  \frac{ - 4 + 3}{2} )

(-4, -1/2)

The table shows a linear function. <br><br> Which equation represents the function.
mote1985 [20]

Answer:

\large\boxed{f(x)=\dfrac{3}{2}x-1}

Step-by-step explanation:

\text{The slope-intercept formula:}\\\\y=mx+b\\\\m\ -\ slope\\b\ -\ y-intercept\\\\\text{The formula of a slope:}\\\\m=\dfrac{y_2-y_1}{x_2-x_1}\\\\\text{From the table we hve two points (0, -1) and (2, 2). Substitute:}\\\\m=\dfrac{2-(-1)}{2-0}=\dfrac{3}{2}

\text{Therefore the equation is}\ f(x)=\dfrac{3}{2}x-1\\\\\text{Check for  the point (4, 5):}\\\\f(4)=\dfrac{3}{2}(4)-1=(3)(2)-1=6-1=5\qquad\ CORRECT

State of the triangles in each pair are similar. If so, State how you know they are similar and complete the similarity statemen
leonid [27]

Answer:

Similar, SSS similarity, ΔLRS

Step-by-step explanation:

First, compare the ratios of the shortest sides:

LN / LS = 112 / 24 = 4⅔

And the longest sides:

LM / LR = 168 / 36 = 4⅔

And the middle:

MN / RS = 154 / 33 = 4⅔

The triangles' sides are proportional.  Therefore, by SSS similarity, the triangles are similar.

If it takes 3,127 feet of computer cable to wire an office building, how much cable will be left if the wire is taken from a 5,0
anyanavicka [17]
This is one of the most complex problems I've seen on Brainly. If you don't understand after reading my lengthy explanation, just tell me.

You have 5000 feet of reel. The office building uses 3127 feet of cable.
So you do 5000-3127 to find the remaining amount of reel.

5000 - 3127 = 1873

Whew! That was quite difficult, wasn't it?
