In if GS ⊥ XJ and XJ⊥EA what is true about GS and EA
svlad2 [7]

Answer:

(GS) || (EA)

Step-by-step explanation:

When two lines are parallel, all four angles formed by the intersection of the two lines are right angles, meaning their angle measures are (90°). This means that alternate interior angles are congruent because all alternate interior angles measures equal (90°). Therefore, by the alternate interior angles converse theorem, lines (GS) and (EA) are parallel.

The alternate interior angles converse theorem states if two angles are congruent and they have the relation of being a part of two lines intersected by a third line, then the two non-intersecting lines are parallel.

An English teacher needs to pick 9 books to put on his reading list for the next school year, and he needs to plan the order in
Nikitich [7]

Answer:   4.37\times10^3

Step-by-step explanation:

Given : Number of choices for novels = 4

Number of choices for plays = 6

Number of choices for poetry books = 5

Number of choices for nonfiction books = 5

Total books =4+6+5+5=20

If he wants to include all 4 novels, then the number of books left to select = 9-4=5

Remaining choices for books = 20-4=16

Number of combinations of n things taking r at a time : \dfrac{n!}{r!(n-r)!}

Then, the number of different reading schedules are possible :_

^4C_4\times^{16}C_5\\\\=\dfrac{4!}{4!(4-4)!}\times\dfrac{16!}{5!(16-5)!}\\\\=(1)\times\dfrac{16\times15\times14\times13\times12\times11!}{120\times11!}\\\\=4368=4.368\times10^3\approx4.37\times10^3

Hence, the required answer is 4.37\times10^3.

Please help meeee I don't know this
Vanyuwa [196]

Answer:

\boxed {m = -\frac{5}{7}}

Step-by-step explanation:

Use the <u>Slope Formula</u> to determine the slope of two given points:

m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}

First Point: (x_{1} , y_{1})

Second Point: (x_{2}, y_{2})

-Substitute both points:

First Point: (5, 11)

Second Point: (19, -1)

m = \frac{-1 - 11}{19 - 5}

-Solve for the slope:

m = \frac{-1 - 11}{19 - 5}

m = \frac{-10}{14}

\boxed {m = -\frac{5}{7}}

Therefore, the slope is -\frac{5}{7}

Complete the proof by providing the missing reasons. given:cb bisects bd,de bisects ec, cb=de. prove dbc=ced. . . CB=DE,CB BISEC
Alexus [3.1K]
Base on your question were the are proofs that is given are this are: CB bisects BD, DE bisects EC, CB=DE. So answer your question you must understand first your given statements and realize that CBD and DEC are both right triangles because they are a perpendicular segment so i conclude that the answer should be CBD=DEC because they are both right angles
