Answer:
18
Step-by-step explanation:
Answer:
y=-3/13x-89/13
Step-by-step explanation:
m=y²-y¹/x²-x¹
m=(-8)-(-5)/5-(-8)
m=-3/13
y-y=m(x-x1)
y-(-8)=-3/13(x-5)
y+8= -3/13x+15/13
-8 -8
y=-3/13x-89/13
Answer:
28
Step-by-step explanation:
P(red marbles) = 3/7
no. if red marbles = 12
12/x = 3/7
3x = 12 x 7
3x = 84
x = 28
the total number of marbles are 28.
hope it helps .
all the best
Answer: y=x
The slope of the perpendicular line is the opposite reciprocal. So you do -(-1/1) which equals 1. So now we have y=x+b. Plug (3,3) into this and you get 3=3+b. So b=0 and the equation is y=x
