Which inequality below satisfies the solution set graphed on the following number line?

Which Inequality Below Satisfies The Solution Set Graphed On The Following Number Line?

Answers

Answer 1

Answer:

D.

Step-by-step explanation:

The function must have the range  -3 to 5.

2x^2 - 4x - 30

= 2(x^2 - 2x - 15)

= 2(x + 3)(x - 5)

so the critical points are -3 and 5.

When x = -2 f(x) = 2* 1 * -7 = -14 <= 0

when x = 4 f(x) = 2 * 7 * -1 <= 0.

when  x= 0  f(x) < 0

So its the last option.

Step-by-step explanation:

the value of a straight line is 180°. so create an equation that sets the angle values to equal 180°, then solve for b:

(3b-6)+(b-2)=180

3b-6+b-2=180

A restaurant sells tea for

$1.50 per drink. The cost of drinks, F(d), can be found by using the function F(d) = 1.5d. If the restaurant sells no more

than $150 in drinks in a day, what is a reasonable domain and range


Thank you!


Domain:



Range:

Answers

Answers:

Domain is  [tex]0 \le d \le 100[/tex]

Range is  [tex]0 \le F(d) \le 150[/tex]

==============================================

Explanation:

The most money made from selling drinks is $150. Divide this over the cost per drink to get 150/(1.50) = 100; indicating that at most 100 drinks are sold per day. This is the largest that d can get because d represents the number of drinks sold.

The smallest d can get is d = 0 to mean that no drinks are sold.

In short: d is between 0 and 100, including both endpoints. We write [tex]0 \le d \le 100[/tex] to indicate this. This is the domain because the domain represents all the possible inputs allowed.

---------------------------------------------------

The range is the set of allowed outputs.

If we plugged in d = 0, then you would find F(d) = 0 as well. If you don't sell any drinks, then you earn $0. This is the smallest item in the range.

On the other side of things, the largest item in the range is 150 because this value was given to us. It's the upper limit or ceiling value of how much money is made from drinks. You can also find this by plugging d = 100, the largest domain value, into the function to get F(d) = 150.

Therefore the range is [tex]0 \le F(d) \le 150[/tex] to indicate that F(d) is between 0 and 150 inclusive of both endpoints.

The perimeter, p, of an equilateral triangle varies directly as the length of a side, s, if
the perimeter is 153 cm when the side length is 51 cm, what would be the perimeter if
the side length is 81 cm.

Answers

Variation can be direct, inverse or joint.

The perimeter is 243 cm

Represent perimeter with P and side lengths with L.

So, we have:

[tex]\mathbf{P\ \alpha\ L}[/tex]

Express as an equation

[tex]\mathbf{P = kL}[/tex]

Where k is the constant of variation.

Make k the subject

[tex]\mathbf{k = \frac PL}[/tex]

So, we have:

[tex]\mathbf{\frac{P_1}{L_1} = \frac{P_2}{L_2}}[/tex]

Make P2 the subject

[tex]\mathbf{P_2 = L_2 \times \frac{P_1}{L_1} }[/tex]

Substitute the given parameters

[tex]\mathbf{P_2 = 81 \times \frac{153}{51} }[/tex]

[tex]\mathbf{P_2 = 81 \times 3 }[/tex]

[tex]\mathbf{P_2 = 243}[/tex]

Hence, the perimeter is 243 cm

The area of a square is any given one of the sides, squared. We can take this information and apply it to this problem. If the area is 1/49 km squared, we can take the square root of this to find the length of each side.

The square root of 1 is 1, and the square root of 49 is 7, so the answer is 1/7 km for each side.

how do i change the fraction into a decimal?
3/4 as a decimal?

Answers

Answer:

0.75

Step-by-step explanation:

1. To change 3/4 into a decimal, you have to divide 3 by 4.

2. (Check out the image below to see how to divide 3 by 4.)

Answer:

3/4 is expressed as 0.75 in the decimal form.

Step-by-step explanation:

Fractions and decimals are two ways to represent the same numbers. A decimal number can be defined as a number whose whole number part and fractional part is separated by a decimal point. A fraction is represented as a numerical value that is defined as a part of a whole.

To convert any fraction to decimal form, we just need to divide the numerator by the denominator.

Here the fraction is 3/4 which means we need to divide: 3 ÷ 4.

* Use the attatched images for steps*

Therefore, 3/4 = 0.75.

Thus, 3/4 is expressed as 0.75 in the decimal form.

The corresponding roots of the quadratic equations are given.

What are Quadratic Equations?

Quadratic expressions are polynomial equations of second degree.

The general form of a quadratic equation is ax² + b x + c = 0.

1. x² = 49

Find the square root.

x = ±√49 = ±7

2. x² - 27 = 0

x² = 27 = 9 × 3

x = √27 = √(9×3) = √9 × √3 = ±3√3

3. 3x² - 36 = 0

3x² = 36

Divide 3 on both sides.

x² = 12

x = √12 = √(4 × 3) = ±2√3

4. 9x² = 0

x = 0

5. 5x² - 15 = 0

5x² = 15

x² = 3

x = ±√3

6. 2x² - 144 = 0

2x² = 144

x² = 72

x = √72 = √(36 × 2) = ±6√2

7. (x + 3)² = 9

x + 3 = √9

x + 3 = ±3

x = 3 - 3 = 0 and x = -3 - 3 = -6

8. 4x² - 100 = 0

4x² = 100

x² = 25

x = ±√5

9. 5x² = 40

x² = 8

x = √8 = √(4 × 2) = ±2√2

10. 3x² - 12 = 0

3x² = 12

x² = 4

x = ±2

11. (x - 5)² = 121

x - 5 = √121

x - 5 = ±11

x = 11 + 5 = 16 or x = -11 + 5 = -6

Hence the solutions are found.

Kishore bought a basket containing 30 orangs for rs 310. If he sells the orangs at rs 12 each , what Would be it's profit or loss?

Answers

Given : Kishore bought a basket containing 30 oranges for rs 310. If he sells the oranges at rs 12 each , what Would be it's profit or loss?

Solution :

Cost price of oranges = rs.310

As we know that each oranges cost rs.12

So, selling price of oranges is 30 × 12 = rs.360

Now, finding profit or loss

Profit = Selling Price - Cost Price

Profit = rs.360 - rs.310

Profit = rs.50

So, the profit is 50

Answers

Answer:

Given equation is (8/y) = 2/(y-2) +1

=> (8/y)- 2/(y-2) = 1

=> [8(y-2)-2y]/(y-2)y = 1

=> (8y-16-2y)/(y²-2y) = 1

=> (6y-16)/(y²-2y) = 1

=> y²-2y = 6y-16

=> y²-2y -6y+16 = 0

=> y²-8y+16 = 0

The standard form is y²-8y+16 = 0.
