HELP PLEASE ASAP I WILL MARK BRAINLIEST
prisoha [69]

Answer:

BC = 24

Step-by-step explanation:

FD = 36, FE = 15 and CD = 18

By secant theorem.

DE • DF = CD • DB

(36 - 15) • 36 = 18 • DB

DB = 42

BC = DB - CD

BC = 42 - 18

BC = 24

PLEASE MARK ME AS BRAINLIEST AND HAVE A NICE DAY :)

How do I find the slope from a table if the value added onto each (x,y) value is different? Please help!!! I need the slope!
Bess [88]
ANSWER:
________

Line q = 3
Line v = -1/2

FORMULA
__________

y2 - y1 / x2 - x1

EXPLANATION:
_____________

First, we need to find the slope for line a only

We need to select two points from line q. The ones I selected are (-3,18) and (2,33)

y2 = 33
y1 = 18

x2 = 2
x1 = -3

33 - 18 = 15
2 - -3 = 5

15/5 = 3

Next, we need to find the slope for line v.

The two points I picked are (0,8) and (10,3)

y2 = 8
y1 = 3

x2 = 0
x1 = 10

8 - 3 = 5
0 - 10 = -10

5/-10 = -1/2

And that’s how you get your answer :)

Factor the following using GCF and show work. 6x^2+42x-18
aniked [119]
The greatest common factor is 6. Thus means we divide every part of the expression by 6.

6x^2/6 = x^2
42x/6 = 7x
-18/6 = -3

Your new expression is 6(x^2 + 7x -3).
