Help please! I need an answer asap

Answers

Answer:

-2/3

Step-by-step explanation:

h(x)=2x-6/4x^2+8

You know that h is equal to -1 so you have to plug that into x.

2(-1)-6/4(-1)^2+8. Simplify this to get -2-6/4+8 which is equal to -8/12. The GCM of 8 and 12 is 4 so you have to divide both sides by 4. This will make the fraction -2/3.

If this has helped you, please mark the answer as brainliest

Answer: [tex]h(-1) = \frac{-2}{3}[/tex]

Step-by-step explanation:

You simply substitute -1 for x

h (-1) = 2 (-1) - 6 ÷ (4 × -1² + 8)

h (-1) = (-2 - 6) ÷ (4 × 1 + 8)

h (-1) = (-2 -6) ÷ (4 + 8)

h (-1) = -8 ÷ 12 = -2 ÷ 3

h (-1) = ⁻²/₃

Celeste ordered a pack with 7 pens and 1 stapler. Each pen weighed 7 grams. The stapler weighed 486 grams. How many kilograms did the order weigh? Note: 1 kilogram = 1,000 grams

Answers

Answer: 0.535kilogram

Step-by-step explanation:

From the question, we are informed that Celeste ordered a pack with 7 pens and 1 stapler and that each pen weighed 7 grams while the stapler weighed 486 grams.

The weight of the order will then be:

= 7 pens + 1 stapler

= 7(7 grams) + 1(486 grams)

= 49 grams + 486 grams

= 535 grams

To convert grams to kilogram,, we have to divide by 1000. This will be:

= 535/1000

= 0.535kilograms

The order weigh 0.535kilograms

PLEASE HELP!!! The man who killed Alexander Hamilton will probably never appear on U.S. currency. Aaron Burrs early career showed great promise. Born in Princeton, New Jersey, he was the son of a president of Princeton College and the grandson of a famous clergyman. At age 16, Burr graduated from Princeton. His pursuit of further studies was interrupted by the American Revolution. Burr distinguished himself on the field and briefly joined General Washingtons staff. However, Burrs relationship with Washington was never close or easy, and the young hero returned to the battlefield, eventually leading a regiment.7 After he left the army, Burr began a hugely successful legal career in New York, often crossing paths with Alexander Hamilton in social and professional settings. He became active in state politics and was elected to the U.S. Senate. Burrs relationship with Hamilton turned unfriendly as the men assumed leadership of opposing political parties in New York. In the disputed presidential election of 1800, Hamiltons role in ensuring that Burr was elected vice president rather than president increased the antagonism between the two men.8 Burr reached the peak of his political career as vice president. After that, he was alienated from his own party. Aware that he would not be nominated again, he unsuccessfully ran for governor of New York. Burr blamed Hamilton for his political troubles. In July 1804, the U.S. vice president fatally wounded his rival in a duel.9 Burrs misfortunes and misconduct did not end with the duel. He became involved in a plot to detach the Louisiana Territory from the United States and apparently to crown himself emperor. He was tried for treason in 1807 but acquitted. In disgrace, Burr fled to Europe for four years. He returned to New York to practice law and died in penniless obscurity at the age of 80.Which detail in paragraph 7 MOST clearly contributes to the development of one of the central ideas of the passage? A. the growing hostility between Hamilton and Burr B. the success of Burrs legal career C. Burrs election to the U.S. Senate D. Burrs interactions with Hamilton in various settings Flexibility exercise can be done everyday. True or false Tanisha and Bess are sisters. Tanisha is half as old as Bess.

Assignment: Adaptations to New Environments ExplorationDirections: Read the descriptions of the four islands presented in the lesson.1. List two new traits that each new species of rat might demonstrate as it adapts to the conditions on each island.2. Introduce one of the four new rat species to another island and describe one challenge it would encounter and one success as it adapts to its new environment.List the traits of each new species of ratThe rat on Island A:1.2.The rat on Island B:1.2.The rat on Island C:1.2.The rat on Island D:1.2.Describe a challenge that would be encountered and a success of one of the new rats to another new environment (example: the rat living on Island B now moves to Island D).Island AThe island is fairly flat with an occasional hill. The ground is made of soft dirt, and several species of shrubs grow toward the center of the island. There is no animal life on land, but the water around the island is teeming with fish. The island is surrounded by a coral reef, and the shore is sandy with no algae growing on it. Freshwater is available.Island BThis island has a rocky shoreline. Numerous tide pools dot the island along the shore where the wave action is somewhat sheltered by rocky outcrops. The tide pools host barnacles, abalone, sea urchins, and crabs. Algae grow all around the island; however, the growth of algae is quite sparse in the tide pools where the various animals feed. The current is quite strong along the rocky outcrops where the algae grow best. Freshwater is available.Island CThe island is somewhat barren. A few species of cactus thrive on the bare rocks, and a large, cactus eating tortoise inhabits the island. A species of very large birds nests on the island annually. The birds build their nests on the rocks and protect their eggs from the sun by standing over the nests with outspread wings. The nests are always found on the windy side of the island, which is somewhat cooled by offshore breezes.Island DThis island is an extinct volcano. Vegetation on the island changes as the altitude increases. Grasses grow at the base of the volcano, but farther up the volcanos slope, the grasses give way to low shrubs. Halfway up, the island becomes quite lush; tropical plants and trees dominate the landscape. At this altitude, the island experiences frequent rain showers. Two species of birds inhabit the island. One is a raptor that preys on the smaller birds. The other fishes the waters approximately one mile offshore. Both of the bird species nest in trees.
