Which equation could have been used to create this graph?

Answers

Answer: y = 4x
Explanation: Slope means rise/run. You can use the points (0,0) and (1,4) to find the answer to the question. Rise basically is how much the distance is between the two points going vertical (up). And when you do that, you should get 4 units. Now, you're at (0,4) since you moved the point up 4 and you want to find how many spaces away is (0,4) from (1,4) horizontally, which is 1 unit. The rise/run is 4/1, which is the slope.

Length x width= area
3/4 x blank= 3/2
So then you can divide area by the given length
3/2 divided by 3/4= 2
And to check your answer you would put 2 in as your width
3/4 x 2= 6/4. And 6/4 reduces to 3/2

What is Inequality?

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

Given:

Model Inequality:  4x + 2.5x ≥  45.

Now, solving for inequality

4x + 2.5x ≥  45.

(4 + 2.5)x ≥ 45

6.5x ≥ 45

x ≥ 45/ 6.5

x≥ 6.92

x≥ 7 (approx)

So, the max price for sunglasses and beach balls = 4(6.92)+ 2.5(6.92)

                                                                                   = $44.91

Thus, the left money is = 45- 44.91 = $ 0.09

−6x + 6y = 6 −6x + 3y = −12

Answers

Answer:

x = 0

y = 2

Step-by-step explanation:

−6x + 6y = 6 −6x + 3y = −12

-6x+6x+6y-3y = 6

3y = 6

y = 2

checking:

6-6x+3.2 = -12

6-6x+6 = -12

12-6x = 12

x = 0

checking 2:

since x = 0 we ignore it and its multipliers from the equation:

6y=6+3y = 12

6.2 = 12 (check)

6+3.2 = 12

6+6 = 12 (check)

Which of the following sets are disjoint?

a) Men and uncles

b) Aunts and uncles

c) Women and Aunts

d) They are all disjoint ​

Answers

Answer: b) Aunts and uncles

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

Explanation:

The term "disjoint" is another way of saying "mutually exclusive". If two sets are disjoint, then they have nothing in common. Put another way, if two sets are disjoint, then it's not possible to be part of both sets at the same time.

In this case, it is not possible to be both an aunt and an uncle simultaneously for any one person. So this is why choice B is the answer.

A box of cereal states that there 99 calories in a 3/4 cup serving. What is the unit rate for calories per cup how many calories are there in 2 cups of the cereal

Answers

Answer

The unit rate should be 132 cal, and the total cal in 2 cups should be 264.

Step-by-step explanation

How you will get the unit rate is by multiplying 99 cal by 4 then dividing that amount by 3 to get 132. After that you can multiply 3 into that to get 264

In the figure, BE||CD, B is the midpoint of AC, and E is the midpoint of AD

Answers

Answer:

A. 8

Step-by-step explanation:

BE = ½(CD) (midsegment theorem)

BE = 2x - 10

CD = 12

Plug in the values

2x - 10 = ½(12)

2x - 10 = 6

Add 10 to both sides

2x - 10 + 10 = 6 + 10 (addition property of equality)

2x = 16 (addition property of equality)

Divide both sides by 2

2x/2 = 16/2

x = 8 (division property of equality)

Answers

Answer:

x=67

Step-by-step explanation:

Two ways to solve it:

1st way: Just looking at it, x is definitely not 180° because it’s to big of an angle, it is definitely not 113° because it’s still to big of an angle, and it’s also not 90° because it doesn’t form a right angle. So it must be 67°.

2nd way: Since two angles in a straight line add up to 180°, you can subtract 113° from 180° to find what x is. You can tell that 180° - 113° is equal to 67°

So either way, the answer is: x=67

The discrimination of a quadratic function is 13. Which is a true statement about the roots of the function?​

Answers

Answer:

If the discrimination of a quadratic function is 13, then the function will have two distinct real roots.

Step-by-step explanation:

Given the quadratic function

[tex]y=ax^2+bx+c[/tex]

where D = b²-4ac is called the discrimination of a quadratic function.

The discriminant D=b²-4ac indicates the type of roots the equation may have.

If D > 0, then the equation has two distinct real roots.

Given that the discrimination of a quadratic function is 13.

i.e. D = 13

As D > 0, so the function will have two distinct real roots.

Thus, we conclude that if the discrimination of a quadratic function is 13, then the function will have two distinct real roots.

Mom and I went to our local store to buy craft paper, but we became upset because it was out of stock. Egyptian Society and EconomyLike most ancient civilizations, Egypt had a hierarchical social structure. At the top of society was the pharaoh, who was not only the monarch, but also considered to be a living god. Next were government officials and priests, and then there was a large middle class composed of merchants, soldiers, farmers, and artisans. Most Egyptians belonged to this class, and farming was the most usual occupation. At the bottom of the social ladder were slaves and servants. Because of its location near the Mediterranean & Red Seas, it was easy for Egyptians to trade with other civilizations nearby, such as Nubia, Palestine, and Greece. Exports included grain, linen, and papyrus; imports included lumber, gold, and incense.

These explorations led the Europeans to discover North America. The ocean journey from England, France, or Spain to North America was 3,000 miles of unknown dangers, but it led to discoveries. Explorers made these treacherous voyages for three main reasons: religion, wealth, and competition. These voyages of discovery began in the eleventh century.Historical records indicate that Leif Eriksson, a Viking explorer, was the first man to reach North America around 1000. Leif is credited with landing along the coastline of present-day Newfoundland. A Viking settlement was established and occupied for several years before Eriksson left to return to his homeland. He died around 1020.Much later, Christopher Columbus left his homeland in 1492 to seek wealth in the form of trade items. The Italian explorer was destined for China but erred in direction and arrived on Watling's Island in the Bahamas. It was a long and dangerous journey. Upon arrival, Columbus dedicated the newly discovered land to the Spanish King and Queen of Aragon. Then, Columbus made three more voyages to North America in 1493, 1498, and 1502. To the very end, Christopher Columbus was adamant that he discovered a trade route to China. He denied ever being to North America.Credited with sailing around the southern tip of Florida, Spanish explorer Juan Ponce de Leon had several adventures in the New World. His journey around Florida occurred in 1513. At the time, he thought Florida was an island. When he returned to Florida in 1521, he was wounded by a poisoned arrow, which ultimately ended his life.Afterward, Hernando De Soto, a Spanish adventurer, left to explore present-day Florida in 1538. He and his men traveled thousands of miles through the South. They were the first Europeans recorded to have crossed the Mississippi River in 1541.Sir Walter Raleigh was a soldier, a writer, and a friend of the Queen of England. Around 1587, he sent English colonists to a region later called Virginia. The colony is believed to have been located in North Carolina. Since the people arrived together, their previous lifestyle and beliefs were transplanted to the New World.Finally, Rene Robert de La Salle was French. Historical data credits de La Salle as being the first explorer to traverse the Mississippi to its mouth at the Gulf of Mexico. He claimed the land that bordered the Mississippi River (about a third of present-day United States) for France on April 9, 1682. He built numerous forts along the route, but the settlers were often terrorized by the natives.These brave explorers from England, France, and Spain have left their legacy. As a result of their adventures, many people now enjoy North America's religious diversity, natural resources, and independence.What is the overall structure of this text?a. Cause and effectb.
