Lydia graphed ΔDEF at the coordinates D (−2, −1), E (−2, 2), and F (0, 0). She thinks ΔDEF is a right triangle. Is Lydia's asser
alukav5142 [94]

Answer:

No; the slopes of segment EF and segment DF are not opposite reciprocals.

Step-by-step explanation:

The slope between two points O(e, f) and X (g,h) is given as:

slope\ of\ |OX|=\frac{h-f}{g-e}

The slopes of segment EF and segment DF are given below:

slope\ of\ |EF|=\frac{0-2}{0-(-2)}=-1\\\\slope\ of\ |DF|=\frac{0-(-2)}{0-(-1)}=2\\

For triangle DEF to be a right triangle, DF and EF are supposed to be perpendicular to each other. Two line are said to be perpendicular if the product of their slope is -1, i.e the slope of one line is the negative reciprocal (opposite reciprocal) of the other line.

Since the slope of DF and EF are not opposite reciprocals,  ΔDEF is not a right triangle.

dimaraw [331]

Answer:

\frac{12}{n}

Step-by-step explanation:

Since the numerator are like terms so you just add them together and leave the denominator the same.

Multiply the binomials and simplify so that they are in standard form. Show all your work.
tatuchka [14]

Answer: The answer is = 2x^2 -11x-40

Step-by-step explanation: a= 2x, b=5, c= x, d =8

= 2xx + 2x (-8) + 5x +5(-8)

+ (-a)=-a

then simplify =2xx-2 -8x+5x.8

2xx=2x^2

2.8x=16x

5.8=40

=2x - 16x + 5x- 40
