The slope of the line below is -1/7 use the coordinates of the labeled point to find a point-slope equation of the line A. y-3=1/7(x-3)
B. y+3=1/7(x+3)
C. y-3=-1/7(x-3)
D. y+3=-1/7(x+3)

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius

: )

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.

idk idk idk idk idk

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
