Step-by-step explanation:

Orlando bought a new couch for 1,968, using the furniture store's finance plan. He will pay 164 a month for 12 months. Which equation can Orlando use to find out how much money he still owes after each month of the plan?

a) y = 164x - 1,968
b) y =1,968 - 164x
c) y = 164x
d) y= 1,968 + 164x

Answers

Answer:

B

Step-by-step explanation:

Total(1,968) - x(164) = new value

It’s B because u need to subtract the total money he needs to pay (1968) from how much he is paying a month (164x) to get how much he still needs to pay have a good day

Answer:

(3x)¹²

Step-by-step explanation:

(3x³)⁴ is in form of (e³)⁴ which can be written as e³×⁴

= e¹²

so (3x³)⁴ can be written as (3x)¹²

Answer:

3x¹²

Step-by-step explanation:

According to the power rule of exponents, to simplify a power of a power, you multiply the exponents and keep the base the same. In this case, 3 and 4 are the exponents. 3 times 4 is 12. So the answer would be 3x to the power of 12.

Answer:

Step-by-step explanation:

1) Determining the nature of roots:

Quadratic equation: ax² + bx +c = 0

Find D (Discriminant) using the  D = b² - 4ac

If D = 0 , then the two roots are equal.

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

If D < 0, then the roots are complex/ imaginary.

One can find the sum and product of the roots using the below mentioned formula.

1) sum of roots = [tex]\frac{-b}{a}[/tex]

2) Product of roots = [tex]\frac{c}{a}[/tex]

If sum and product of the roots are given, one can frame the quadratic equation by   x² - (sum of roots)*x + product of roots = 0

2) i) x² - 6x + 9 = 0

a = 1 ; b = -6  and c = 9

D = (-6)² - 4 * 1 * 9 = 36 - 36 = 0

D = 0. So, two equal roots

ii) x² - 4x + 3 = 0

a = 1 ; b = -4 ; c = 3

D = (-4)² - 4 * 1 * 3 = 16 - 12 = 4

D > 0. So, two distinct real roots.

iii) x² - 4x - 3 = 0

a = 1 ; b = -4 ; c = -3

D = (-4)² - 4*1*(-3) = 16 + 12 = 28 > 0

D > 0. So, two distinct real roots.

iv) x² - 4x + 7 = 0

a = 1 ; b = -4 ; c = 7

D =(-4)² - 4 *1 *7 = 16 - 28 = - 12

D< 0. So, two imaginary/ complex roots.

Write an equation of the line that passes through the point (6,2) and is perpendicular to the line y=3x+3

Answers

Answer:

y = - [tex]\frac{1}{3}[/tex]x + 4

Step-by-step explanation:

To find the slope of a perpendicular line, find the negative reciprocal of the slope.

The slope is 3 so the slope of the perpendicular line would be - [tex]\frac{1}{3}[/tex]

________________

Then use point slope form to find the equation of the perpendicular line:

y - [tex]y_{1}[/tex] = m (x -  [tex]x_{1}[/tex] )

point = (6, 2)

slope = - [tex]\frac{1}{3}[/tex]

y - 2 = - [tex]\frac{1}{3}[/tex] (x - 6)

________________

If you want it in slope intercept form, you can just rearrange the equation:

y = 2 - [tex]\frac{1}{3}[/tex]x +2

y = - [tex]\frac{1}{3}[/tex]x + 4

Answers

Answer:

34

Step-by-step explanation:

We actually don't care what amount of paper is white, we just need the amount per truck. If there were 2 trucks, they would each take half of the total amount of paper. If there were 3 trucks, they would each take a third of the total amount of paper. And so on for 4,5,6,etc.

For 28 trucks, they would each take a twenty-eighth of the total amount of paper. So, the amount each truck takes is just [tex]952/28=34[/tex].

So, the answer is [tex]\boxed{34}[/tex] and we're done!

People shouldnt compare themselves to celebrities or models because it is difficult to look exactly like that person, we are all created individually and uniquely, thus we arent meant to look exactly like one another. Rather than constantly comparing ourselves to one another, we should realize that we are all beautiful in our own way. I believe that if people live with this mentality they will be happier and comfortable with themselves.I believe that true beauty comes from within. Outer looks and physical beauty eventually disintegrate, but inner beauty will always remain. The personality and heart of every individual are so unique and special to that person, thus making them truly beautiful. I believe that people that possess this true type of beauty radiate and bring a special light onto others everyday. Inner beauty lights up a persons face and brings warmth to others. This type of beauty is so unique to individuals and will always remain, unlike outer beauty. As opposed to outer beauty, inner beauty is what makes a person who they are; it makes them unique and special in many ways. The beauty within a person transcends outwardly, thus making a person even more beautiful than they actually appear to be. According to Elizabeth Kubler- Ross People are like stained-glass windows. They sparkle and shine when the sun is out, but when the darkness sets in their true beauty are revealed only if there is a light from within.I believe that if people live with this mentality that everyone is beautiful inside and out, the world will be a happier place and everyone will be accepted despite their differences. 3.
