A=pir^2
C=2pir
=>r=C/2pi
g(c)=pi(C/pi)^2
Answer:
Step-by-step explanation:
If A then B is a conditional statement.
Answer:

Step-by-step explanation:
Notice that with the provided information they are given you not ust the slope of the line (-2), but also the y-intercept (the point where the line crosses the y-axis which happens when x=0).
So you can directly write the equation of the line in slope-intercept form [
where "m" is the slope and "b" the y-value when x=0].
Such gives us:

Answer:
x = -172
Step-by-step explanation:
x + y = -11 and 161 - y = 0
hence using elimination method :
161 + x = -11
x = -11 - 161
x = - 172
