Answer:

Step-by-step explanation:

We need all three sides to be congruent to use the SSS theorem of congruency. Either the sides are marked on the picture congruent or are congruent by reflexive property -a side is congruent with itself. Other wise the sides are not congruent.

a)Yes (AB≅CD, BC≅DA, CA≅CA)

b) ΔABC≅ΔCDA

a)No ( AC≅BC, CD≅CD, AD not ≅ BD)

b) ΔACD is not ≅ ΔBCD

a)NO (DM≅CM, AD not ≅BC, AM not ≅BM)

b)ΔADM is not≅ΔBCM

a) Yes (AC≅EG, CR≅GO, RA≅OE )

b) ΔACR≅ΔEGO

a) No (QR≅SD, QS≅QS, RS is not≅ DQ)

b)ΔQRS is not≅Δ SDQ

How do I determine if a math question is statistical or not

Naddik [55]

A statistical question will have more than one answer. Questions like, “How old are the students in my school?”or “What time did the students in this class get up this morning?” are examples of a statistical question. Pretty much if it involves asking more the one people it’s a statistical question because it will lead to more than one answer.

Based on the table of values below, find the slope between points where x = 5 and where x = 10.

horsena [70]

Hello!

$\large\boxed{m = 1}$

Use the slope formula to determine the slope between the points:

m = (y2 - y1) / (x2 - x1)

Plug in the values:

m = (7 - 2) / (10 - 5)

m = 5 / 5

m = 1

Confirm that f and g are inverses by showing that f(g(x)) = x and g(f(x)) = x. (5 points)

lara31 [8.8K]

F(x)=(x-8)/(x+7). g(x)=(-7x-8)/(x-1). Plug in g(x) into f(x), f(g(x))=[(-7x-8)/(x-1)-8]/[-7x-8)/(x-1)+7], which can be simplified as (-7x-8-8x+8)/(-7x-8+7x-7)=-15x/-15=x. Plug in f(x) into g(x), g(f(x))=[-7*(x-8)/(x+7)-8]/[(x-8)/(x+7)-1]=(-7x+56-8x-56)/(x-8-x-7)=-15x/-15=x, as desired.
