Help me find the area of this circle
ch4aika [34]
The area would be approximately 153.94.

The area of a circle is pie multiplied by r^2. 

So you have the radius, which is r. Plug in r. Technically you have two numbers because pie equals approximately 3.14.

A=3.14(7)^2

Y = 4x-9<br> y = x-3<br> Which method and why? Solve, shoving all work
vodomira [7]

Answer:

(2,-1)

Step-by-step explanation:

The ys in both questions are isolated on one side of the equation in both. The numerical coefficient of both is 1. Therefore you should equate the the left side of each equation to the other left side. The solution is the easiest one to solve because there is only 1 unknown on both sides.

4x - 9 = x - 3                      Subtract x from both sides.

4x-x - 9 = -3                       Combine

3x -9 = - 3                          Add 9 to both sides

3x - 9+9 = - 3+9

3x = 6                                Divide by 3

3x/3 = 6/3

x = 2

===============

Now use the second equation to solve for y

y = x - 3

y = 2 - 3

y = -1

==============

The solution is (2,-1)
