Answer:

D. 2y < 2

Step-by-step explanation:

To find the equation with shaded area below the boundary line, all we need to do is to examine each inequality and find the one which gives

+y < ( a constant)

We can leave out the x term for this.

For example:

A. y>5  clearly it is shaded above the line (because of the > sign)

B. -3y <3 => 3y > -3    so again it is shaded above

C. -3y                   is not even an inequality

D. 2y < 2              clearly it is shaded BELOW

E. 4y >12              clearly it is shaded above

See also attached diagram.  The answer is represented by the purple area.  All the other areas are shaded above the boundary line.

Answer:

2

Step-by-step explanation:

Answer:

a) we know that:

the tens digit exeeds the units digit by 3, then if we have two digits

ab.

and b, the digit for units is equal to r.

then a, the digit for tens, is equal to r + 3.

Then, if r = 4, we have that the digit for tens is r + 3 = 7

and the number is 74.

b) if n is an integer, then we know that 2*n is an even number.

Now, the next even number is always 2 units away, then the next even number to 2*n is:

2*n + 2 = 2*(n + 1)

Answer: C

Step-by-step explanation:

y = ax + bx + c is the general equation for quadratic function. While the discriminant D is

D = b^2 - 4ac

You are given the equation:

y = x^2 + 3x - 4

Where a = 1, b = 3 and c = -4

Substitutes all the parameters into the discriminant D formula

D = 3^2 - 4 × 1 × -4

D = 9 - ( - 16 )

Open the bracket

D = 9 + 16

D = 25

Therefore, D = 25 and the roots are rational

Answer:

You've described a system of equations:

x+y=6

x*y=4

The easiest way to solve is with substitution. If you rearrange the first equation, you'll find that y = 6-x. Substitute this into the second to get x(6-x) = 10

This is a quadratic equation that you should be able to solve with the quadratic formula. Be aware that the answers are complex.

Answer:

132%

Step-by-step explanation:

The population of Peru = 10904

The population of Franklin = 25248.

Difference = 25248-10904=14,344

Expressing as a percentage of the population of Peru

[tex]\dfrac{14344}{10904} X 100[/tex]

=132%

Therefore, the population of Franklin is 132% more than the population of Peru.

Answer:

377 choices

Step-by-step explanation:

From the above question, we are told that

A restaurant offers 6 choices of appetizer, 8 choices of main meal and 5 choices of dessert. A customer can choose to eat just one course, or two different courses, or all three courses.

Let us represent each choice by :

A = Appetizer = 6

M = Main meal = 8

D = Dessert = 5

a) The combination of the 3 choices together

AMD=6 × 8 × 5=240

b) AM= Appetizer and Main meal

= 6 × 8 = 48

c) AD= Appetizer and Dessert

= 6 × 5 = 30

d) MD = Main meal × Dessert

= 8 × 5 = 40

e) A,M,D (each alone)=

Appetizer + Main meal + Dessert

= 6 + 8 + 5

= 19

Assuming all choices are available, how many different possible meals does the restaurant offer?

This is calculated as:

AMD + AM + AD + MD + A,M,D

240 + 48 + 30 + 40 + 19

= 377 choices

The Volume of the smaller prism is 37.5 ft³.

Prism is a three-dimensional structure that has identical polygon bases, and other faces are identical parallelograms.

The volume of the prism is determined by the formula

V = Bh

B is the base area and h is the height of the Prism.

The scale factor is given as 1/4, as the volume of the larger prism is given.

The volume of the larger prism is 2400 ft³

the side lengths will be multiplied by 1/4

Let the base area is for the larger prism the area for the smaller prism will be equal to

A = (1/16) a

The height of the larger prism is h.

Height of the smaller prism will be (1/4)h

The volume of the smaller prism = (1/16)*(1/4) Volume of the Larger Prism

The volume of the smaller prism = 2400 / (16*4)

The volume of the smaller prism = 37.5 ft³.

Answer:

x = 7.5

Step-by-step explanation:

2/3x + 2= 21/3

Subtract 2 from each side

2/3x + 2-2= 21/3-2

2/3x = 21/3 - 6/3

2/3x =15/3

2/3x = 5

Multiply each side by 3/2 to isolate x

2/3x * 3/2 = 5 *3/2

x = 15/2

Answer:

50

Step-by-step explanation:

The perimeter of a Triangle is the sum of it's 3 sides.

We are given two sides here which is side length 5.6 and a side of length 19.7

Let's us represent the third side as x

Therefore

x + 19.7 + 5.6 = Perimeter of the triangle

We would have this equation

But it is important to know that every side of a triangle must be less than the sum of the other two sides, hence

x < 19.7 + 5.6

x < 25.3

Adding 25.3 to both sides to make the left side equal to the perimeter

perimeter = x+25.3 < 25.3 + 25.3 = 50.6

Therefore, 50.6 is the smallest whole number that is larger than the perimeter of the triangle in the question above.

Therefore, the biggest whole number smaller than the perimeter of the above triangle is 50

Answer:

39

Step-by-step explanation:

25.3<x>14.1

Because 5.6 +19.7=25.3

Because 19.7-5.6=14.1

And 25.3+14.1=39.4

WE NEED WHOLE NUMBER A LITTLE BIT SMALLER (cause thats the question)

Answer:

8.7 cm

Step-by-step explanation:

The question is a 2-two-step Pythagoras theorem. (c^2 = a^2 + b^2)

Consider as such, If I were to draw a diagonal line along the base of the cube what is the length of the diagonal line. To find out that we use the theorem. We can substitute a for 5 and b for 5 as well. So

a^2 +b^2 = c^2

5^2 + 5^2 = c^2

25 + 25 = c^2

√50 = c

Then since the line side of the cube is on a 3d angle we need to do the same process again but now using the imaginary diagonal line that we just calculated and the height (5).

a^2 +b^2 = c^2

√50^2 + 5^2 = c^2

50 + 25 = c^2

√75 = c

c = 8.6602...

when rounded to 1 d.p.

c = 8.7

in this case, m, the slope, is 7.

b, the y -intercept, is -3.

Answer:

[tex]\boxed{Option C}[/tex]

Step-by-step explanation:

Given equation is

=> y = 7x-3

Comparing it with standard slope intercept equation:

Step-by-step explanation:

Statements A, B, E, and F are true. The second sample was taken at random using a fair sampling technique.

Probability is synonymous with possibility. It is concerned with the occurrence of a random event.

Probability can only have a value between 0 and 1. Its simple notion is that something is very likely to occur. It is the proportion of favorable events to the total number of events.

The correct statement is as follows;

A) The second sample is random.

B) The second sample is likely to be more representative of the population.

D) The second sample will give a better representation because is it larger.

F) Community members are more likely to listen to the radio station an average of 12 hours a month than 20 hours a month.

The second sample was taken at random using a fair sampling technique.

Because the research using the larger data size is accepted rather than that of the smaller data, community members are more likely to listen to the radio station an average of 12 hours a month than 20 hours.

A research's sample size is a crucial consideration. Additionally, the second sample is probably a better indicator of the broader population.

Hence statements A, B, E, and F are true.

Step-by-step explanation:

Answer:

( y + b - a - 3d)(y + b + a + 3d).

Step-by-step explanation:

y^2 + 2by + b^2 - a^2 - 6ad - 9d^2

= y^2 + 2by + b^2 - (a^2 + 6ad + 9d^2)

= (y + b)^2 - (a + 3d)^2

This is the difference of 2 squares so we have

(y + b - (a + 3d))(y + b + (a + 3d))

= ( y + b - a - 3d)(y + b + a + 3d)

Answer:

[tex]9.05 * 10^{7} kg[/tex]

Step-by-step explanation:

Given

[tex]Statue\ of\ Liberty\ =\ 2.04 * 10^5 kg[/tex]

[tex]Washington\ Monument\ =\ 9.07 * 10^7 kg[/tex]

To get the number of kilograms the Washington Monument weighs more than the Statue of Liberty, we simply calculate the difference;

Difference = Washington Monument - Statue of Liberty

[tex]Difference = \ 9.07 * 10^7 kg - \ 2.04 * 10^5 kg[/tex]

Expand [tex]10^7[/tex]

[tex]Difference = \ 9.07 * 10^{5+2} kg - \ 2.04 * 10^5 kg[/tex]

[tex]Difference = \ 9.07 * 10^{5} * 10^2 kg - \ 2.04 * 10^5 kg[/tex]

Take out the common factor in the above expression

[tex]Difference = 10^{5}\ (\ 9.07 * 10^2 kg - \ 2.04\ kg)[/tex]

[tex]10^2 = 100;[/tex] so we have

[tex]Difference = 10^{5}\ (\ 9.07 * 100 kg - \ 2.04\ kg)[/tex]

[tex]Difference = 10^{5}\ (\ 907 kg - \ 2.04\ kg)[/tex]

[tex]Difference = 10^{5}\ (904.96\ kg)[/tex]

Open bracket

[tex]Difference =904.96 * 10^{5} kg[/tex]

Write in standard form

[tex]Difference =9.0496 * 10^2 * 10^{5} kg[/tex]

[tex]Difference =9.0496 * 10^7 kg[/tex]

[tex]Difference =9.05 * 10^7 kg[/tex] (Approximated)

Hence, he Washington Monument weigh more than the Statue of Liberty by about [tex]9.05 * 10^{7} kg[/tex]

Option (B)

Step-by-step explanation:

Equations of the lines shown in the graph are,

[tex]y=\frac{1}{4}x-2[/tex] and [tex]y=\frac{7}{4}x+4[/tex]

For equation (1),
