y varies inversely with x. y=15 when x=10, find y when x=5

Answers

Answer 1

y
=
25
Explanation:
y
=
k
x
;where
x
and
y
are variables and
k
is constant
or
5
=
k
10

or
k
=
5
(
10
)

or
k
=
50

So Equation becomes
y
=
50
x

When
x
=
2

y
=
50
2

or
y
=
25

Convert the equation from standard form to slope-intercept form.

Answers

Answer:

y=x-1

Step-by-step explanation:

The equation is currently in standard form which is a+b=y and slope-intercept is y=mx+b where m is the slope and b is the y-intercept. To change the form we must move the terms around using Properties of Equality.

First, subtract 1 from both sides

x-y-1=1-1

x-y-1=0

Then, add y to both sides

x-y-1+y=0+y

x-1=y

So that is the equation in slope-intercept form with a slope of 1 and a y-intercept of -1.

Answer:

y=x-1

Step-by-step explanation:

It is y=x-1 because first when we do ANYTHING first. We leave the y on the left side of the equation, since the slope y=mx+b has the y always on the left side. So we subtract x from both sides and we get -y=-x+1. We are NOT DONE yet, so after this, we divide both sides by -1. Why? This is because you cannot have a negative y. Dividing both sides by -1 you finally get y=x-1. If this is trouble some to read, I will also put how to solve the problem down below. :)

Let's solve for y.

x−y=1

Step 1: Add -x to both sides.

x−y=1+−x

−x

−y=−x+1

Step 2: Divide both sides by -1.

−y/ −1 = −x+1 /−1

y=x−1

eqn of line

5x-y=-9

Step-by-step explanation:

Answer:

y = 5x + 9

Step-by-step explanation:

Assuming you require the equation.

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 5 , thus

y = 5x + c ← is the partial equation

To find c substitute (- 1, 4) into the partial equation

4 = - 5 + c ⇒ c = 4 + 5 = 9

y = 5x + 9 ← equation of line

are real numbers closed under cube root?

Answers

Answer:

Real numbers are not closed under cube root

Step-by-step explanation:

The cube of each real number is increasing as the real numbers increases, giving a functional or one to one relationship. Therefore, the cube roots of real number have also a one to one relationship.

Given that a cube root of a number, ∛x = y therefore, y³ = x, we have that all real numbers, excluding zero, have one cube root, and two complex and conjugate roots

For the real number, 8, we have the cube roots given as follows;

∛8 = 2

Also, ∛8 = -1 + √3i and -1 - √3i

Given that not all cube roots of 8 are real numbers we have that real numbers are not closed under cube root.

dozen cookies can she make in 5 hours?

Please help fast!!

Answers

We already know that 0.5 of an hour, or half of an hour, is 30 minutes. We also know that 3 dozen equals 36. With this information, we can conclude that Natalie can make 72 cookies in one hour. 72 times 5 is 360. 360 divided by 12 is 30, so, Natalie can bake 30 dozen, or 360, cookies in five hours.

the answer would be 10 dozen cookies

Scientists mixed local bees with African ones to create a bee that would make more honey. They ended up with something much different. The new bees evolved in unexpected ways. They multiplied and migrated north. These Africanized honeybees are now known as killer bees for several scary but legitimate reasons.Killer bees are far more aggressive than their relatives. They have been known to attack in great numbers, even when there has been no direct threat on their hives. They have swarmed because of loud noises, dark clothing, bright jewelry, and even strong perfume. They will chase a person for more than a quarter of a mile and remain angered for up to 24 hours.Killer bees are also dangerous because of their sting. While most bees take up to 30 seconds to attack, killer bees sting in just 3 seconds. Their venom is no stronger than a regular bee's, but when one killer bee stings, others follow. With up to 80,000 members in a colony, victims are quickly overwhelmed. So many stings in such a short time can cause allergic reactions. Victims enter a state of shock, lose blood pressure, and in many cases, die.A final reason why "killer" has been added to their name is the unfortunate number of deaths they have caused. Experts estimate that the Africanized honeybee moves at a rate of about 200 miles each year. As the bees claim new territory, they claim new victims as well. More than 1000 people have been stung to death in South and Central America. There have been rising numbers of attacks in Mexico and a handful in the United States. Once a swarm sets sights on a victim, it is very difficult for the victim to escape. Once attacked, it is very difficult to survive.Thankfully, there has been no killer bee invasion as some once predicted. Although there is no need for panic, the threat of the killer bee is real and should be taken seriously. It is good practice to call a professional to remove beehives in your area. If you are stung multiple times by any insect, you should always seek medical attention. You may not be expert enough to tell the difference between a killer bee and a less dangerous one, so be smart. It is better to be safe than sorry.Which sentence from the conclusion paragraph best rephrases the author's thesis?a)Thankfully, there has been no killer bee invasion as some once predicted.b)Although there is no need for panic, the threat of the killer bee is real and should be taken seriously.c)You may not be expert enough to tell the difference between a killer bee and a less dangerous one, so be smart.d)It is better to be safe than sorry.
