Answers

the answer to this is -25

f(x) = -x^2 +7x-13
f(-3) = -(-3)^2 + 7(-3) - 13
f(-3) = 3^2 -21 -13
f(-3) = 9-21-13
f(-3)= -25

For what value of x is m∥n ?

Enter your answer in the box.

x =

Answers

Answer: x = 6

Step-by-step explanation:

Angles 1 and 8 are alternate exterior angles, so they are equal.

So you can create an equation to solve for x

12x−20 = 2x+40 Subtract 2x from both sides. Add 20 to both sides

10x = 60

x = 6

If you need the m∠1, Substitute 6 for x. (2x+40)° 2(6) +40= 12+40 m∠1= 52°

m∠8=(12x−20)° 12(6) - 20 = 72-20 m∠8 = 52°

Step-by-step explanation:

Peter is saving money to buy an MP3 Player. After one month, he has $50. After two months he has $85. After three months, he has $120. He plans to keep saving at the same rate. How long will it take Peter to save enough money to buy an MP3 Player that costs $295?

Answers

Answer:

9 months

Step-by-step explanation:

peter is saving 35 dollars per month.

295=35x

295/35=8.42 which is less than 295

9 is an approximate answer

35*9 equals 315, which is enough to pay 295 and have 20 dollars left over

solve for x 3x+10 3x -28 will mark brainest answers are 1. 33 2. 34 3. 35 4. 36 ty so much 1 left godbless

Answers

Answer:

1. x = 33

Step-by-step explanation:

3x+10 + 3x -28 = 180

3x + 3x = 180 + 28 - 10

6x = 198

x = 198/6

x = 33

Answer:

Step-by-step explanation:

By the same side interior angle theorem, we can find that 3x + 10 and 3x - 28 are supplementary. Knowing this, we can make the equation:

(3x + 10) + (3x - 28) = 180

Now we can solve for x. Combine like terms.

6x - 18 = 180

Add 18 from both sides.

6x = 198

Divide both sides by 6.

x = 33

So the value of x would be 33.

I hope you find my answer and explanation to be helpful. Happy studying.

Which of all the following inequalities is true for all real values of x?

Answers

Answer:

C. 1/(x^2 +1) > 0

Step-by-step explanation:

The cube of a negative number is negative, eliminating choices B and D for certain negative values of x.

1/x^2 is undefined for x=0, so cannot be compared to zero.

The value 1/(x^2+1) is positive everywhere, so that is the expression you're looking for.

1/(x^2 +1) > 0

Adult honeybees, known as worker bees, were disappearing from their hives, seemingly abandoning them. Few or no dead bees were found in the hives, while the queen and larvae were alive and well but without the swarm of worker bees that typically attended them to keep them alive. What had happened?The phenomenon became so widespread that it soon received a name, Colony Collapse Disorder (CCD) . There was no denying that CCD was a problem; after all, American agriculture depends on the work of honeybees and other pollinators. At least three-quarters of the crops grown in the United States depend on honeybee pollination for their survival. These include such staples as strawberries, blueberries, apples, broccoli, asparagus, and almonds. Without them, both farmers and anyone who enjoys fresh fruits and vegetables will suffer.But what is causing this problem? Scientists have rigorously studied a variety of possible causes, ranging from genetically modified crops to climate change to cell phone towers. Sadly, nothing has shown to be the cause of the problem. The most likely culprits are pathogens, or disease-causing organisms. These have been found in larger numbers in colonies affected by CCD than in those unaffected. But these pathogens have included various viruses and bacteria, some found in greater concentrations in different parts of the country. If CCD is caused by a single disease, identifying that disease will be difficult.The CCD epidemic is most likely the result of multiple causespathogens, poor nutrition, pesticides, lack of genetic diversity, and habitat loss. Efforts to prevent colony loss have been mildly successful. The number lost has declined each year since 2008. But until a solution to this problem is found, CCD will remain a concern that will threaten not only the future of bees, but also of the people who rely on the food that they help produce.What are the central ideas in "Colony Collapse Disorder"?Select the two correct answers.A. The most likely cause of CCD is pathogens.B. Adult bees are abandoning their colonies.C. Honeybees generally live in the same colonies.D. Few dead bees were found near the colonies.
