Question

djjo · Answer

Part A: Explain why the x-coordinates of the points where the graphs of the equations y = 4–x and y = 2x + 3 intersect are the solutions of the equation 4–x = 2x + 3. 

Part B: Make tables to find the solution to 4–x = 2x + 3. Take the integer values of x between −3 and 3.

djjo · Answer

I have part A I'm just confused with Part B

djjo · Answer

Is this right?:

x        y
-3      64 = 2
-2      16 = -2
-1       4 = .25
0        0 = 8
1        -4 = 16
2        1/16 = 32
3         1/64 = 64

I believe what B is saying is make tables and it has to range between -3 and 3

anonymous · Answer

Make 3 columns on your table: x, 4-x, and 2x+3

anonymous · Answer

Use x value from -3 to 3, and look to where 4-x is equal to 2x+3. That value of x will be your solution.

ok thx

anonymous · Answer

Eg.

x     4-x     2x+3
-3     7          -3

and so on
