A set of equations is given below:Equation C: y = 2x + 6


Equation D: y = 2x + 2

Which of the following best describes the solution to the given set of equations

Answers

Answer 1
Answer:

If you would like to know what best describes the solution to the given set of equations, you can calculate this using the following steps:

y = 2x + 6
y = 2x + 2
____________
y = y
2x + 6 = 2x + 2
6 = 2
6 - 2 = 0
4 = 0 ... no solution

The correct result would be no solution.

Use the given graph to determine the limit, if it exists. A coordinate graph is shown with a horizontal line crossing the y axis at three that ends at the open point 2, 3, a closed point at 2, 1, and another horizontal line starting at the open point 2, -2.

Find limit as x approaches two from the left of f of x. and limit as x approaches two from the right of f of x..

Answers

The limit is the value of the function when you approach the closest possible  to the x value without getting to that x value.

The closed point (2,1) is not used to calculate the limit. The closed point (2,1) represents the value of the function at x = 1, but the limit is not the value of the function.

Use the horizontal line that comes from the left and ends at the open point (2,3) to find the limit of f(x) when x approaches to 2 from the left.

That limit is 3, because you can get as close as you want to 3 when you approach x = 2 from the left.

Use the horizontal line that starts at the open point (2-2) and goes to the right, to find the limit of f(x) when x approached to 2 from the right.

That limit is -2 because you can get as close to -2 when you approach x = 2 from the right.

It is important that you know that the definition of limits do not include the value of the function at the point where you want to state the limit.

This result, limit of f(x) when x approaches 2 from the left  = 3  and limit of f(x) when x approaches 2 from the right = -2, means that the limit of the function when x approaches 2 does not exist.

The limit exists if and only if the two lateral limits exists and are equal.

Help please?If sin O = -sqrt3 over 2 and n < O < 3 pi over 2, what are the values of cos O and tan O?​

Answers

Answer:

  • cos(θ) = -1/2
  • tan(θ) = √3

Step-by-step explanation:

You know that ...

  • cos(θ)² = 1 - sin(θ)²
  • tan(θ) = sin(θ)/cos(θ)
  • cosine is negative in the third quadrant (where π < θ < 3π/2)

Using what you know about the relationships of these trig functions, you can find ...

  cos(θ)² = 1 - ((-√3)/2)² = 1 - 3/4 = 1/4

  cos(θ) = -1/2 . . . . . negative square root of 1/4

__

  tan(θ) = sin(θ)/cos(θ) = ((-√3)/2)/(-1/2)

  tan(θ) = √3

Which of these is the algebraic expression for the verbal expression "ten times the difference of a number and twelve?"10(x − 12)
x − 12 ⋅ 10
12(x − 10)
10 ⋅ x − 12

Answers

Hello,

Answer A

10*(x-12)
first x-12 (parenthesis) : difference of some number and 12
second 10* the result before==> the product of 10 by the diffrence of x and 12.

Answer:

Step-by-step explanation:

10(x − 12)

x − 12 ⋅ 10

12(x − 10)

10 ⋅ x − 12

Solve the equation show all steps

Answers

Answer:

x= 5

Step-by-step explanation:

4x-6=x+9

Move the -6 to the other side of the equation by adding 6 to each side.

4x-6 + 6 =x+9 + 6

4x = x+15

Now move the x on the right side of the equation to the left side of the equation by subtracting x from each side.

4x - x = x + 15 - x

3x = 15

Now to isolate the x, divide both sides of the equation by 3.

3x/3 = 15/3

x = 5

Check your answer by substituting x = 5 into the original equation:

4x-6=x+9

4(5) - 6 = 5 + 9

20 - 6 = 14

14 = 14 >>> so this answer, x=5, is correct.
