Answer:

6

Step-by-step explanation:

XY = 3x – 1, YZ = 5, and XZ = 5x – 8,

We know that XY + YZ = XZ, so

3x - 1 + 5 = 5x - 8

3x + 4 = 5x - 8

3x + 12 = 5x

12 = 2x

6 = x

\\ 1. (3x ^{2}  + 2xy + 7) - (6x ^{2}  - 4xy + 3) \\  = 3x ^{2}  + 2xy + 7 - 6x ^{2}  + 4xy - 3 \\  = 3x ^{2}  -  {6x}^{2}  + 2xy + 4xy + 7 - 3 \\  =   { - 3x}^{2}  + 6xy + 4 \\ 2. \:  {9x}^{2}  - 2x + 3 - ( {4x}^{2}  + 7x - 5) \\  = 9x ^{2}  - 2x + 3 - 4x ^{2}  - 7x  + 5 \\  = {9x}^{2}  -  {4x}^{2}  - 2x - 7x + 3 + 5 \\  =  {5x}^{2}  - 9x  + 8 \\ 3. \:  {x}^{2}  - 5x + 6 \\  =  {x}^{2}  - (3 + 2)x + 6 \\   = {x}^{2}  - 3x - 2x + 6 \\  = x(x - 3) - 2(x - 3) \\  = (x - 3)(x - 2) \\ hope \: it \: helps \\ good \: luck \: on \: your \: assignment

Is this right ? Im honestly confused
fgiga [73]

Answer:

In step by step

Step-by-step explanation:

For #1, everything is perfect.

For #2, you wrote your functions out incorrectly, but your x input and y output are correct

#3 is a little messed up.

Your function is f(x)=-3x+1. Your given x's are -3, -1, 0, 1, 2, and 3. Plug all of these in.

1. f(-3)=-3(-3)+1

  • f(-3)=9+1
  • f(-3)=1

2. f(-1)=-3(-1)+1

  • f(-1)=3+1
  • f(-1)=4

3. f(0)=-3(0)+1

  • f(0)=0+1
  • f(0)=1

4. f(1)=-3(1)+1

  • f(1)=-3+1
  • f(1)=-3

5. f(2)=-3(2)+1

  • f(2)=-6+1
  • f(2)=-5
