Which of these is the quadratic parent function?

Answer:

y = -7x+34

Step-by-step explanation:

We have 2 points, so we can find the slope

m = (y2-y1)/(x2-x1)

    = (6--1)/(4-5)

    = (6+1)/(4-5)

     = 7/-1

    = -7

We can use point slope form to make an equation

y-y1 = m(x-x1)

y--1 = -7(x-5)

y+1 = -7(x-5)

Distribute

y+1 = -7x+35

Subtract 1 from each side

y+1-1 = -7x+35-1

y = -7x+34

Answer:

Step-by-step explanation:

- figure out slope intercept form and write an equation

- draw a graph

- go up positive two on the y axis and to the right one and mark the spot

- mark -3 on the y axis

- use a ruler t connect the two points

[tex]\large\boxed{59\,\text{years old}}[/tex]

In this question, it's asking you to figure how old the oldest person in the company is.

To solve this, we would need to gather some important information from the question.

Important information:

With the information above, we can get closer to our answer.

We need some prior knowledge to solve this. The "range" is the highest number subtracted by the lowest number.

This means that the the 22 was already subtracted to get 37.

What we would do is reverse to solution and add 22 to 37 to get our highest number (oldest person).

[tex]37+22=59[/tex]

When you add them together, you should get 59.

This means that the oldest person in the company is 59 years old.

Answer:

Age of oldest person = 59 years

Step-by-step explanation:

Points to remember

Range of a data set is the difference between smaller value and larger value value in the set.

It is given that, the youngest person in the company is 22 years old. The range of ages is 37 years.

To find the age of oldest person

Range = 37 years

Youngest age =  22 years

Range = oldest age  - youngest age

oldest age = range + youngest age

 = 37 + 22

 = 59

Age of oldest person = 59 years

Answer:

He needs to sell the rest of the oranges at 75 paisa each.

Step-by-step explanation:

Consider the given information that, Shishir bought 4000 orange at 70 paisa each.

Note: 1 rupees = 100 paisa

Thus, 70 paisa = 70/100 rupees = 0.70 rupees

Therefore, the cost price of 4000 oranges is:

4000×0.70 rupees = 2800 rupees

The selling price of 2000 oranges is:

2000×0.90 rupees = 1800 rupees

The number of oranges now Shishir have:

4000 - 2000 - 400 = 1600

He wants to make a profit of RS 200. Thus the selling price of 4000 oranges should be:

2800 rupees + 200 rupees = 3000 rupees

He earned 1800 rupees by selling 2000 oranges at 90 paisa. So, the remaining amount that he needs to make with 1600 oranges is:

3000 rupees - 1800 rupees = 1200 rupees

Therefore, the cost of one orange is:

1600 oranges = 1200 rupees

1 orange = 1200/1600 rupees

1 orange = 0.75 rupees

Hence, he needs to sell the rest of the oranges at 75 paisa each.

Answer:

Step-by-step explanation:

Put the values of x = 1 and y = -3 to the equations of a line and check the equality:

1. 4x - y = 7

4(1) - (-3) = 4 + 3 = 7   CORRECT

2. 2x + 5y = 4

2(1) + 5(-3) = 2 - 15 = -13 ≠ 7

3. 7x - y = 15

7(1) - (-3) = 7 + 3 = 10 ≠ 15

4. x + 5y = 21

1 + 5(-3) = 1 - 15 = -14 ≠ 21

Answer:

All of them are polynomials except c.

Step-by-step explanation:

Polynomials are in the form:

[tex]a_0+a_1x+a_2x^2+a_3x^3+a_4x^4+a_5x^5+a_6x^6+\cdots +a_nx^n[/tex]

You can see here there are no extra symbols like square root, cube root, absolute value, and so on on the variable x...

We also don't have division by a variable.  All the exponents are whole numbers.

a) While it has a square root, it is not on a variable so a is a polynomial.  The exponents on the variables are whole numbers.

b) b is a polynomial also because all the exponents are whole numbers.

c) This is not a polynomial because there is a square root on a variable.

d) This is a polynomial.  All the exponents are whole numbers.

Answer:

The correct option is A. The given statement is true.

Step-by-step explanation:

Given statement: If A and B are two points in the plane , the perpendicular bisector of AB is the set of all points equidistant from A and B.

Let a line is perpendicular bisector of AB at point D and C be a random point of perpendicular bisector.

In triangle ACD and BCD,

[tex]AD=BD[/tex]                          (Definition of perpendicular bisector)

[tex]\angle ADC=\angle BDC[/tex]                          (Definition of perpendicular bisector)

[tex]DC=DC[/tex]                       (Reflexive property)

By SAS postulate of congruence,

[tex]\triangle ACD\cong \triangle BCD[/tex]

The corresponding parts of congruent triangles are congruent.

[tex]AC\cong BC[/tex]               (CPCTC)

[tex]AC=BC[/tex]

The distance between A to C and B to C are same. So, the set of all points on perpendicular bisector are equidistant from A and B.

The given statement is true. Therefore the correct option is A.

Final answer:

The statement is True because the perpendicular bisector is defined as the line that divides a line segment into two equal parts at its midpoint and is perpendicular to the segment, making all points on it equidistant from both endpoints of the segment.

Explanation:

The statement 'If A and B are two points in the plane, the perpendicular bisector of AB is the set of all points equidistant from A and B' is True. The definition of a perpendicular bisector is that it is a line which is perpendicular to another line segment (AB in this case) and divides it into two equal parts at its midpoint. Therefore, any point on the perpendicular bisector is equidistant from points A and B, which is a direct consequence of the definition.

This is further supported by Theorem 11, which states that if two equal lines in a plane are erected perpendicular to a given line, the line joining their extremities makes equal angles with them and is bisected at right angles by a third perpendicular erected midway between them, ensuring that any point on this third perpendicular (the perpendicular bisector) is equidistant from A and B.

Answer:

d = 5 and a₁ = - 4

Step-by-step explanation:

The n th term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

Given a₃ = 6, then

a₁ + 2d = 6 → (1)

The sum to n terms of an arithmetic sequence is

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]

Given [tex]S_{12}[/tex] = 282, then

6 [ 2a₁ + 11d ] = 282 ( divide both sides by 6 )

2a₁ + 11d = 47 → (2)

We can now solve (1) and (2) for d and a₁

Multiply (1) by - 2

- 2a₁ - 4d = - 12 → (3)

Add (2) and (3) term by term

7d = 35 ( divide both sides by 7 )

d = 5

Substitute d = 5 in (1) and solve for a₁

a₁ + 10 = 6 ( subtract 10 from both sides )

a₁ = - 4

To eliminate one variable the coefficient of a variable should be same with opposite sign.

LEts check with each option

Multiply the first equation by -4 to get  [tex]-16x - 4y = -16[/tex]

the coefficient of x or y are not same when we compare with second equation

Multiply the second equation by -4 to get [tex]- 8x - 24y = -96[/tex]

the coefficient of x or y are not same when we compare with first equation

Multiply the first equation by -2 to get [tex]-8x - 2y = -8[/tex]

the coefficient of x or y are not same when we compare with second equation

Multiply the second equation by -2 to get [tex]- 4x - 12y = -48[/tex]

The coefficient of x terms are same with different sign when compare with first equation

So when we add first and second equation , the x will get eliminated.

Answer:

-7.64%

Step-by-step explanation:

1. Find out how much the car went down in value.

    21,330 - 19,700 = 1,630

2.  Calculate how much 1% of the original value ($21,330) was. One percent is 1/100, which is .01 when divided.

    21,330 × .01 = 213.3

3. Since we now know 1% is equal to $213.30 we can divide $1,630 by $213.30. Doing this will show us how many 1%s are in 1,630.

    1,630/213.30 = 7.64181903

4. There are 7.64181903 1%s in 1,630. Because the car's value went down by 1,630, this also means it went down by 7.64181903% We will round this to the nearest hundredth for simplicity's sake.

    7.64181903 → 7.641 one is less than 6 so we will round down → 7.64

5. The car decreased by 7.64% in value. This will be written as -7.64% because a decrease is negative.

Factoring quadratic expressions with a Leading Coefficient of 1 → In the first equation, you have to find two numbers that when differed to 5, they also multiply to 6, and those numbers are 1 and 6. Now, the tough part for you might be figuring out which term gets which sign. Well, if you look at your MIDST term [5], you would know that the negative symbol goes to 1 [-1] and the positive symbol goes to 6, so your numerator is [x - 1][x + 6]. Now, for the second equation, it is applied the same way, but in this case, we need two numbers that when added to 9, they also multiply to 18, and those numbers are 3 and 6, and automatically receive positive symbols, so your denominator is [x + 3][x + 6]. Now that we have our denominator and numerator, we now set it up: [x - 1][x + 6]\[x + 6][x + 3]. What do you see that is... MAGIC--AL? That is correct! The factors x - 6 neutralize each other and are left with x - 1\x + 3.

Answer:  29/28

Step-by-step explanation:

To add fractions we have to calculate the Least Common Denominator of the denominators. Then we have to change each fraction (using equivalent fractions) to make their denominators the same as the Least Common Denominator. Then we can add (or subtract) the fractions.

LCD (4,7,2)= 4·7 = 28

1/4 = 7/28

2/7 = 4·2/28 = 8/28

1/2 = 14/28

Since the fractions have the same denominator we can add them

7/28 + 8/28 + 14/28 = (7+8+14)/28 = 29/28

B. Graph B

Step-by-step explanation:

A graph with no solutions is one where the lines never intersect.

In Graph A, you have a solution at about (-2, 2).

In Graph C, all real numbers are solutions.

Only statement B is true, so you would select that as the answer.

We can check if statement A is true by finding the ratio of cows to all animals, which we do by finding the total number of animals, 5 + 3 + 2 + 6 = 16.

Then we can say that the ratio of cows to all animals is 2:16, which simplifies to 1:8, so statement A is false.

Statement B is just another way of saying that the ratio of rabbits to all animals is 3:8, so we can see if this is true by finding the ratio of rabbits to all animals. There are 6 rabbits, so it would be 6:16, which simplifies to 3:8. This means that statement B is true.

I hope this helps! Let me know if you have any questions :)
