If you would like to simplify <span>7x − 4y + 5z − 2x − 10y + z, you can do this using the following steps:

</span><span>7x − 4y + 5z − 2x − 10y + z = 7x - 2x - 4y - 10y + 5z + z = 5x - 14y + 6z
</span>
The correct result would be <span>5x - 14y + 6z.</span>

Which of the following equations has no solution?
Ronch [10]

Answer:

B and D

Step-by-step explanation:

Equations with the same x- term on both sides will have no solution

A

4x - 13 = 5(x + 4) = 5x + 20

4x ≠ 5x

This equation has a solution

B

5(3 + 2x) = 10x + 4

15 + 10x = 10x + 4

10x on both sides ⇒ no solution

C

2(3 - 5x) = 8(x + 1)

6 - 10x = 8x + 8

- 10x ≠ 8x

This equation has a solution

D

9x - 6 = 3(3x - 2) = 9x - 6

9x on both sides ⇒ no solution

The following graphs are transformations of f(x) = x^2.
KiRa [710]

Step-by-step explanation:

Let's look at A(x) and see how it is different from f(x)

  1. it is shifted downwards by 8 units
  2. it is not shifted to the left or the right

Therefore A(x) = f(x) - 8

Let's look at B(x) and see how it is different from f(x)

  1. it is not shifted downwards or upwards
  2. it is shifted to the left 7 units

Therefore B(x) = f(x + 7)

Let's look at C(x) and see how it is different from f(x)

  1. it is shifted upwards by 4 units
  2. it is shifted to right by 5 units

Therefore C(x) = f(x - 5) + 4

Let's look at D(x) and see how it is different from f(x)

  1. it is not shifted downwards or upwards
  2. it is not shifted to right by 12  units

Therefore D(x) = f(x - 12)
