Consider these situations. In each situation, is the demand for the good elastic or inelastic?



BLANK As the price of flat-screen televisions decreases, the quantity demanded increases significantly.



BLANK As the price of bread decreases, the quantity demanded changes only slightly.



BLANK As the price of a drug used to treat heart disease increases, the quantity demanded remains unchanged.

Answer:

D

Step-by-step explanation:

Polynomials are always closed with addition, subtraction, and multiplication. Division cannot be used to close a polynomial because when you divide two polynomials, its not going to come out as polynomial. All the other operations after completed will create another polynomial.

Step-by-step explanation:

3x - 2y = 19 ...1

Replace y = x-7 in ...1

3x - 2(x-7) = 19

3x - 2x + 14 = 19

x = 19 - 14

= 5

Replace x = 5 in y = x - 7

y = 5 - 7

= -2

Answer:

$30

Step-by-step explanation:

s + 90 = 120

s = 120 - 90

s = 30

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥

The most simplified inequality form of the amount of money s to spend on shopping is

s ≤ 30

Where s is the amount to spend.

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥

We have,

Mirna earned $120 babysitting during spring break.

She needs to save $90 for the German Club trip.

She wants to spend the remainder of the money shopping.

This means,

The remainder amount,

= 120 - 90

= $30

We can write an inequality as,

s ≤ 120 - 90

s ≤ 30

Where s is the amount of money to spend on shopping.

Thus,

The most simplified inequality form of the amount of money s to spend on shopping is

s ≤ 30

Answer:

x=-7

Step-by-step explanation:

Let's solve your equation step-by-step.

−2(3x+9)=24

Step 1: Simplify both sides of the equation.

−2(3x+9)=24

(−2)(3x)+(−2)(9)=24(Distribute)

−6x+−18=24

−6x−18=24

Step 2: Add 18 to both sides.

−6x−18+18=24+18

−6x=42

Step 3: Divide both sides by -6.

−6x /−6

= 42 /−6

The value of x for the given triangle will be 111°.

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.

The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.

There are many types of triangles such that right-angle triangles, equilateral triangles, and much more.

The sum of all angles inside a triangle is 180°

So,

47° + x° + 22° = 180°

x = 180° - 69° = 111°

Hence "The value of x for the given triangle will be 111°".

Answer:

Step-by-step explanation:

a). When graph w(x) is transformed to r(x) = 4 × w(x), graph of w(x) is vertically  stretched by a scale factor of 4.

Table for the corresponding points will be,

x               w(x)                  r(x)

0                0                  0×4 = 0

15              60               60×4 = 240

30             120             120×4 = 480

45             180             180×4 = 720

b). As discussed in part (a), graph of w(x) will be vertically stretched by a scale factor of 4 to produce the graph of r(x).

c). Since, w(x) = 4x

   and r(x) = 4[w(x)]

   r(x) = 4(4x) = 16x

  r(x) = 16x

Answer:

The city's snowfall in the two-month period was above the historical average by 1/8 feet

Step-by-step explanation:

Fractions

The question provides the following information: In January, a city’s snowfall was 5/8 feet below the historical average. Let's assume the snowfall level to be positive if it's above the historical average and negative otherwise.

The data from January gives us a snowfall of -5/8 feet because it was below the average.

We also know in February, the snowfall was 3/4 foot above the historical average. Following our predefined convention, the data from February gives us a snowfall of +3/4 feet.

To know if the city's snowfall during the two-month period was above or below the historical average, we just need to add them, signs included.

If the result is negative, the two-month period showed a snowfall below the historical average.

Let's find the sum of

[tex]\displaystyle -\frac{5}{8}+\frac{3}{4}[/tex]

The LCM of 4 and 8 is 8, thus:

[tex]\displaystyle -\frac{5}{8}+\frac{3}{4}=\frac{-5+2*3}{8}=\frac{1}{8}[/tex]

Since this quantity is positive, we can say the city's snowfall in the two-month period was above the historical average by 1/8 feet.
