Answer:

The equation of the line will be:

y=-\frac{1}{2}x-6

Step-by-step explanation:

Given

  • slope = m = -1/2
  • point (4, -8)

Point slope form:

y-y_1=m\left(x-x_1\right)

substituting the values m = -1/2 and the point (4,-8)

y-\left(-8\right)=\frac{-1}{2}\left(x-4\right)

y+8=\frac{-1}{2}\left(x-4\right)

subtract 8 from both sides

y+8-8=\frac{-1}{2}\left(x-4\right)-8

y=-\frac{1}{2}x-6

Therefore, the equation of the line will be:

y=-\frac{1}{2}x-6

<span>MP3 player is $60
</span><span>The selling price is $105

</span><span>A classmate says that the markup is 175% because $105/$60=1.75 . Is your classmate correct?

No. IT's not correct

Original price $60
Selling price $105

$105 - $60 = $45

So

45/60 x 100 = 75%

Price is markup 75% from $60 to $105</span>

A class of 40 students elected a class president. There were 12 votes for Candidate A, and 18 votes for Candidate B.
Helen [10]
Hey there, Bulgogi!

The correct answer will be the first one since [I'm assuming] you know that to calculate the percentage of something, it's the amount of that something divided by the total amount but since only 30 students voted [12+18] multiplied by 100.

So, we are calculating the percentage on votes and 12 students voted for Candidate A so our Numerator will be 12 and our Denominator will be the total amount of student who voted, so 30 [or 12+18]

Once put into a fraction, we will get \frac{12}{12+18} which would be equals to 2/5 or 0.4. Now we multiply by 100 and we get a total of 40% for Candidate A.

Knowing that this number, the Golden Ratio, is present not just in mathematics, but may also be present within your own brain an
pychu [463]

The Golden Ratio is a mathematical relationship that exists in art, shapes, nature and the human body. The golden ratio can be present in your body, from the length of your arms and legs when compared to your torso. Fingers is another example because the length of our fingers, each section from the tip of the base to the wrist is larger than the preceding.

The measurement of the human navel to the floor and to the top of the head to the navel is also the Golden ratio. Plastic surgeons and dental surgeons use it to reconstruct the human face. It also appears in everything around us like in the nature and science. It appears on in flower petals because it is believed that each petal is placed to so that each petal gets the best exposure to sunlight. Dolphins, starfish, sea urchins and honeybees also exhibit the proportion like humans. DNA molecules measures 34 angstroms by 21 angstroms at each full cycle of the double helix spiral, these two number are successive numbers. I think that the Golden Ratio is just a freak coincidence that happened.
