Answer:

<u>Given </u>

  • f(x) = 4/(x - 2)

<u>Find</u>

  • [f(x + h) - f(x)] / h

<u>Solution</u>

  • [4/(x + h - 2) - 4/(x - 2)]/h =
  • 4/h[(x - 2) - (x + h - 2)]/[(x + h - 2)(x - 2)] =
  • - 4/h*h/[(x + h - 2)(x - 2)]  =
  • 4/[(x + h - 2)(2 - x)]

Solve the following system of linear equations.
andrey2020 [161]
To solve a problem like this, you will need to use substitution or elimination. For the sake of an example I will solve this using substitution.

First, solve one of the equations for x or y:
3x-5y=-39
3x=-39+5y
X=(-39+5y)/3

Then substitute for the value of x in the second equation:
6x+2y=-42
6((-39+5y)/3)+2y=-42

Solve for y:
-78+10y +2y=-42
-78+12y=-42
12y=36
Y=3

Once you've solved for y, you can plug in it's value to find x:
X=-39+5(3)/3
X=-24/3
X=-8

So, we can conclude that the correct answer is B. (-8,3)

How many soulutions does 4(x+3)-4=8x+10-4x have ?
melamori03 [73]

Answer:

No solutions

Step-by-step explanation:

4(x + 3) - 4 = 8x + 10 - 4x

4x + 12 - 4 = 8x + 10 - 4x

4x + 8 = 4x + 10

4x = 4x + 2

0 ≠ 2

Best of Luck!
