Answer:
KM = 4
Step-by-step explanation:
(segment addition postulate)
(substitution)
Solve for x
Combine like terms
Plug in the value of x
48/6 = 8
each bead weighs 8 grams.
72/8 = 9
9 beads weigh 72 grams.
Answer:
(x+9)^2 + (y-4)^2 = 4
Step-by-step explanation:
The equation for a circle is (x-h)^2 + (y-k)^2 = r^2
I got this graph for 4x = -4x
A) parallel, same slope
Y = 3x + b
9 = 3(5) + b
9 = 15 + b, b = -6
Equation: y = 3x - 6x
B) y = -7x + b
11 = -7 + b, b = 18
Y = -7x + 18
c) y = 9x + b
-16 = 18 + b, b = -34
d) y = -x + b
9 = 2 + b, b = 7
Y = -x + 7
