Answer:
Step-by-step explanation:
A = pi r^2....divide both sides by pi
A / pi = r^2....take the square root of both sides, eliminating the ^2
√ A / pi = r
Answer:
Look at the explanation.
Step-by-step explanation:
Start y=-2x-3 at the Y -3 and X 0, then go up two and to the right one, like a staircase. For y=-x+3 start on Y 3 and X 0 and go down 1 x and 1 y like a downstair staircase with 1 unit down.
Simple,
x+7= 18-2x
you want isolate the variable, x, to find what it's value is...
x+7=18-2x
+2x +2x
Making it..
3x+7=18
still not done...finish isolating the variable...
3x+7=18
-7 -7
3x=11
=
Thus, your answer is, x=
.
Answer:
(1, 0.5)
Step-by-step explanation:
From the graph attached,
x-values are representing the number of games downloaded,
y - values are representing the total cost.
Unit rate means rate of 1 game downloaded.
If we represent this in terms of coordinates,
x- value (game downloaded) = 1
y - value (price of one game download) = $0.5
Therefore, point (1, 0.5) will represent the unit rate.
Option (2) on the top row will be the answer.
