Side 1 = x

Side 2 = 3x+3

There are two of each side so the total is:
54 = 2(x) + 2(3x+3)

From here, just solve for x.

Simplify the expression3(4-x)-3(2-x)
castortr0y [4]

Answer:

1= X

Step-by-step explanation:

Start with PEMDAS

3 x 4 is 12

3x -X is -3X

-3 x 2 is -6

-3 x -X is 3 X NEGITIVE X NEGATIVE = +

so now you got

12 - -3X -6 +3X

again - × - = +

so know you got 12 + 3X -6 +3X

Additions is next in PEMDAS

so 12 -6 is 6 and 3X + 3X is 6X

so 6X =6 so Divide by 6 and you get 1 =X

1) The graph of g(x) is shown below. Which statement given below is FALSE?
Mnenie [13.5K]
<h3>Answer: Choice D </h3>

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

Explanation:

Let's go through the answer choices one by one to see which are true, and which are false.

  • Choice A) This is true because as we approach x = 2 from the left hand side, the y values get closer to y = 1 from the top
  • Choice B) This is true. As we get closer to x = 4 on the left side, the blue curve is heading downward forever toward negative infinity. So this is what y is approaching when x approaches 4 from the left side.
  • Choice C) This is true also. The function is continuous at x = -3 due to no gaps or holes at this location, so that means its limit here is equal to the function value.
  • Choice D) This is false. The limit does exist and we find it by approaching x = -4 from either side, and we'll find that the y values are approaching y = -2. In contrast, the limit at x = 2 does not exist because we approach two different y values when we approach x = 2 from the left and right sides (approach x = 2 from the left and you get closer to y = 1; approach x = 2 from the right and you get closer to y = -2). So again, the limit does exist at x = -4; however, the function is not continuous here because its limiting value differs from its function value.
  • Choice E) This is true because the function curve approaches the same y value from either side of x = 6. Therefore, the limit at x = 6 exists.
