The value of the circumference of circle A with a diameter of 27 cm is three times the value of the area of circle B. What is th
Leya [2.2K]
The answer is 3 cm.

Circle A's diameter is 27, right? However, circle A is 3 times the value of the area of B. Because of that, you need to do 27/3, the inverse, in order to get the diameter of circle B. 

Next, because radius is half of the diameter, you do 9 divided by 3 or 9 times 1/2.

Write a compound inequality that the graph could represent.
Dmitry_Shevchenko [17]
A solid dot on the graph of an inequality indicates that the number is contained within the inequality, so yo should use \leq or \geq to represent that situation, whereas a white dot indicates that the number is not contained within the inequality. 

Our graph is telling us that x is greater or equal than -1, and also x is less than 3. So our inequality will be:

-1 \leq x \leq 3

Find equations for the lines through the point (a,
Free_Kalibri [48]
The line y = mx + c has a slope of m.

Parallel line:
A parallel line will also have a slope of m, and should be of the form
y = mx + k
Because the line passes through the point (a,b), therefore
ma + k = b
k = b - ma
The equation of a parallel line is
y = mx + b - ma
   = m(x-a) + b

Perpendicular line:
A perpendicular line will have a slope of -1/m, because the product of slopes should be -1.
The equation for a perpendicular line is of the form
y = -(1/m)x + k
Because the line passes through (a,b), therefore
-(1/m)a + k = b
k = b + a/m
The equation for a perpendicular line is
y = -(x/m) + b + a/m 
   = -(1/m)(x-a) + b

Answer:
Parallel line: y=m(x-a)+b
Perpendicular line: y=- \frac{1}{m}(x-a)+b
