identify whether each if the following represents a quadratic function or not put yes or no
1. y = x² + 2
2. y = 2x - 10
3. y= 9 - 2x²
4. y = 2x + 2
5. y = 3x² + x² + 2​

Answers

Answer 1

9514 1404 393

Answer:

yesnoyesnoyes

Step-by-step explanation:

The function is quadratic if the highest degree of any term is 2. Equations 2 and 4 have degree 1, so are linear (not quadratic) functions. Equations 1, 3, and 5 have terms of degree 2 (at most), so are quadratic functions.

_____

We assume that two terms of degree 2 in equation 5 is intentional. If one of those is supposed to be of degree 3 (or more), then that function is not quadratic.

Alfredo purchased the following for breakfast:

5 bacons at $.55 each

2 eggs for $1.24

1 apple juice at $1.50 each

What was the total price in dollars and cents Alfredo paid for his breakfast?

Answers

Answer:

$6.73

Step-by-step explanation:

1 bacon = $0.55

5 x $0.55 = $2.75

1 egg = $1.24

2 x $1.24 = $2.48

1 apple juice = $1.50

  $2.75

  $2.48

+ $1.50

————

  $6.73

Therefore, your answer is $6.73.

Answer:

In total, Alfredo paid $6.73 for his meal.

Step-by-step explanation:

To find the cost of all of the food products, multiply the quantity of the food by the prices. So, for example:

Bacon: 5 x $. 55= $2.75

Eggs: 2 x $1.24 = $2.48

Apple Juice: 1 x $1.50 = $1.50.

Now, add.

$2.75+$2.48+$1.50= $6.73

Based on the lesson, identify the first operation needed to solve the following equation.

x/3 - 3 = 11

Answers

Answer:

The first operation is to add, and you are adding 3 to both sides of the equation to isolate the x.

Step-by-step explanation:

Note the equal sign, what you do to one side, you do to the other. You are solving for the variable, x, when solving this equation.

Remember to do the opposite of PEMDAS. PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

~

The first step is to add 3 to both sides of the equation:

(x/3) - 3 (+3) = 11 (+3)

(x/3) = 11 + 3

(x/3) = 14

The second step is to multiply 3 to both sides of the equation:

(x/3) * 3 = (14) * 3

x = 14 * 3

x = 42

42 would be your final answer.

Which statement explains the difference between the graphs of f(x) = 4x^2 and g(x) = -8x^2 ?

A) The graph of g(x) is obtained by flipping f(x) over the y-axis and stretching vertically by a factor of 2.

B) The graph of g(x) is obtained by flipping f(x) over the x-axis and compressing vertically by a factor of 2.

C) The graph of g(x) is obtained by flipping f(x) over the x-axis and stretching vertically by a factor of 2.

D) The graph of f(x) is obtained by flipping g(x) over the y-axis and compressing vertically by a factor of 2.

Answers

Answer:

I think C is best explains

The correct option is B.

The graph of g(x) is obtained by flipping f(x) over the x-axis and compressing vertically by a factor of 2.

What is transformation?

Transformation means to change. Hence, a geometric transformation would mean to make some changes in any given geometric shape.

Given are two functions f(x) = 4x² and g(x) = -8x², we need to see the transformation done in the function f(x) to give g(x).

So,

We can see that there is scale factor of 2, because it was 4 in f(x) and in g(x) it became -8 that means the graph have been compressing vertically by 2 units.

Also, the presence of minus sign, this is because the reflection has been done here about x-axis, so it becomes -8x².

According to our study we can say that the graph is reflected over x-axis and compressing vertically by 2 units.

Hence, the correct option is B.

Kevin made $342 for 18 hours of work. At the same rate, how many hours would he have to work to make $247?

Answers

Answer:

13 hours

Step-by-step explanation:

First you have to find the hourly rate at which money is being earned. To do so you divided the money earn ($342) by how many hours it took to earn (18 hours).

Once you do that you're given $19.00 per hour.

Now take the money earned with the unknown time ($247) and divide it by money being made per hour ($19)  and you're given 13 hours

Answer:

13

Step-by-step explanation:

First, you need to find out how much money he is making per hour. To do that, we need to do $342 divided by 18 hours. This gives us 19. We now know that Kevin is making $19 an hour. Next, do $247 divided by $19. This gives us 13. He would need to work 13 hours to make $247.

A bag contains 3 triangles, 4 squares, 5 pentagons, and 6 hexagons. If one shape is randomly chosen, what is the probability that a hexagon is chosen?​

I’d say that it’s definitely random choice for the squares, pentagons, and hexagons. But, if we are looking at how common it would be between the 3 of them, then I would say that it would be one of the hexagons, because there are more hexagons than any of the other shapes in the bag.
