Answer:

20 = EB

10 = DB

10 = ED

Step-by-step explanation:

By definition, according to this cross-section model, point D is the segment bisector of all segments, according to which segments they are in congruence with. Anyway, here is how it is done:

3x - 8 = x + 4

-3x - 3x

_____________

−8 = −2x + 4

-4 - 4

_____________

−12 = −2x

____ ____

−2 −2

6 = x[Plug this back into all expressions above to get the measurements of 20 = EB, 10 = DB, 10 = ED]

* Since point D the segment bisector, you set the given equations equal to each other, then in the end, plug the x-value back into all expressions to get the length of EB.

I am joyous to assist you anytime.

Answer:

Part 1) ED=10\ units

Part 2) DB=10\ units

Part 3) EB=20\ units

Step-by-step explanation:

we know that

EB=ED+DB

ED=DB -----> given problem

Substitute the given values and solve for x

x+4=3x-8

3x-x=4+8

2x=12

x=6

<em>Find the value of ED</em>

ED=x+4

substitute the value of x

ED=6+4=10\ units

<em>Find the value of DB</em>

Remember that

ED=DB

therefore

DB=10\ units

<em>Find the value of EB</em>

EB=ED+DB

EB=10+10=20\ units

Use the formula d=rt Find t for r = 48.3 m/h and d = 545.79 m.
djyliett [7]
D = 545.79
r = 48.3

Plug in numbers to corresponding variables

545.79 = t(48.3)

Isolate the t, divide 48.3 from both sides

(545.79)/48.3 = 48.3t/48.3

t = 545.79/48.3
t = 11.3

t = A) 11.3 h

hope this helps

Which is a possible number of distinct real roots for a cubic function? Select all that apply.
Neko [114]

Answer:

3

Step-by-step explanation:

3 is a possible number of distinct real roots for a cubic function.

The maximum possible number of distinct roots are equal to the degree of any polynomial function.

Hence quadratic function has 2 roots

Cubic has 3

Linear has 1

Solve for the indicated variable in each scientific formula. c=wtc/1000 for w
Hitman42 [59]
First, multiply both sides by 1000
1000*c = w*t*c

Since c is on both sides, they would cancel each other out
1000 = w*t

Divide both sides by t.
w = 1000*t
