Mathematics
1 answer:
Neporo4naja [7]3 years ago
7 0

Answer:

x = -3

Step-by-step explanation:

To solve this, you need to isolate the variable x, this means only one side of the equation should have the variable x. To do this, you need to do the opposite operation from what's given (if it's addition, use subraction; if it's multiplication, use division; these work vise versa)

  • Subtract 9 from both sides of the equation. This gives you 10x = 4x - 18.
  • Subtract 4x from both sides of the equation. This gives you 6x = -18.
  • Divide both sides by 6. This gives you x = -3

The final answer is x = -3

Consider the arithmetic sequence:
prisoha [69]

Answer:

<em>Answer: D</em>

Step-by-step explanation:

<u>Arithmetic Sequences </u>

The arithmetic sequences are those where any term n is obtained by adding or subtracting a fixed number to the previous term. That number is called the common difference.

The equation to calculate the nth term of an arithmetic sequence is:

a_n=a_1+(n-1)r

Where

an = nth term

a1 = first term

r   = common difference

n  = number of the term

We are given the arithmetic sequence:

10, 12, 14, 16, ...

Where a1=10 and

r = 12 - 10 = 2

Thus the general term is:

a_n=10+(n-1)2

Operating:

a_n=10+2n-2

a_n=8+2n

Answer: D

The line with equation y = 2 x + 3 is reflected in the x -axis. Which of the following is the equation of the new line?
aliina [53]

Answer:

The equation of the new line is y = -2x - 3

Step-by-step explanation:

Reflecting a function over the x-axis:

Suppose we have a function y = f(x)

Suppose y' is the function y, reflected over the x-axis. Their relation is:

y' = -y

In this question:

Line with equation y = 2x + 3

Reflection over the x-axis:

We have that:

y = -(2x + 3) = -2x - 3

The equation of the new line is y = -2x - 3
