What is the answer to the problem

Mathematics
1 answer:
Rom4ik [11]3 years ago
6 0

Answer:

1. Yes

2. Yes

3. No

6. Yes

7. No

See descriptions and reasons why below.

Step-by-step explanation:

A function is a rule that assigns exactly one output to every input. This means that no input value (x value) can repeat and have different output values *y values).

1. Output values repeat for different input values. This is a function still.

2. Quadratic equations for a U shape graph and do not have repeating inputs so it is still a function.

3. A circle is not a function. It has repeating inputs. Draw a vertical line down through the circle. It intersects at more than one point. Not a function.

4. Not readable in the picture.

5. Not readable in the picture.

6. Yes it is a function. Draw a vertical line and it intersects only once. Therefore, it has no repeating inputs.

7. Not a function. The x values or inputs repeat 25 and 36 with different output values each time.

3x-6y=6 in function notation
JulijaS [17]
Subtract 3x from both sides:

-6y = -3x + 6

divide both sides by -6 to get y by itself:

y = 1/2x - 1

function notation is rewriting y as a function:

f(x) = 1/2x -1

QUICK!!!
Svetlanka [38]

Answer:

Option B is the right choice.

Step-by-step explanation:

Given:

An are CE and an inscribed angle CBE.

Measure of inscribed angle CBE = 25 °

We have to find the measure of the arc CE.

Concept:

  • An inscribed angle is an angle with its vertex on the circle.
  • The measure of an inscribed angle is half the measure the intercepted arc.
  • Measure of inscribed angle = 1/2 × measure of intercepted arc .

To find the measure of arc CE.

⇒ \angle CBE = \frac{1}{2} \times m\ (arc\ CE)

⇒ 2\times \angle CBE = m\ (arc\ CE)

⇒ 2\times 25 = m\ (arc\ CE)

⇒ 50 = m\ (arc\ CE)

Measure of intercepted arc CE = 50 degrees.

The measure of arc CE = 50° so, option B is the right choice.

Which of the following is the solution set of the given equation?<br><br> (x - 3) - 2(x + 6) = -5
Vlad1618 [11]

Answer: x=−10

Step-by-step explanation:

x−3−2(x+6)=−5

x+−3+(−2)(x)+(−2)(6)=−5(Distribute)

x+−3+−2x+−12=−5

(x+−2x)+(−3+−12)=−5(Combine Like Terms)

−x+−15=−5

−x−15=−5

−x−15+15=−5+15

−x=10
