Answer:
N and P are equal to 48 degrees
Step-by-step explanation:
1. 3y^2=12y^2−144
2. Subtract 3y^2 from both sides
3. add 144 to both sides
4. 9y^2= 144
5. Divide both sides by 9
6. y^2 = 16
7. Take the square root of 16 ( which is y=±√16)
8. y = 4 or y = -4
(in this case, Y would equal 4 since the angles are not negative lol)
9. Plug 4 into the equations
10. Compare each answer to see if they are equal

Answer:
∠ N = ∠ P = 48°
Step-by-step explanation:
Δ KMP and Δ LJN are similar ( AA postulate ), then corresponding angles are congruent, that is
∠ P = ∠ N
12y² - 144 = 3y² ( subtract 3y² from both sides )
9y² - 144 = 0 ( add 144 to both sides )
9y² = 144 ( divide both sides by 9 )
y² = 16 ( take the square root of both sides )
y = [tex]\sqrt{16}[/tex] = 4
Then
∠ N = 3y² = 3(4)² = 3(16) = 48² = ∠ P

On a trip, Miguel drives at an average speed of 55 miles per hour. After 2 hours, the odometer on his car reads 4583. Write an equation to represent the reading on the odometer m after h hours.
Answers
Answer:
[tex]m=4473-55h[/tex]
Step-by-step explanation:
Step one
Given data
speed= 55 miles per hour
time taken = 2 hours
Hence the distance covered is
from v=d/t
distance= velocity * time
distance= 55*2
distance= 110 miles
this means that the initial reading of the odometer is
=4583-110
=4473 miles
after h hours the distance covered will be
distance = 55*h
distance= 55h
the reading of the odometer m is
m= initial reading-distance
Hence the reading of the odometer m is expressed as
[tex]m=4473-55h[/tex]
Answer:
Correct
m=55h+4473

Answer:
x= 7/6
Step-by-step explanation:
collect the like terms. so in this problem -4x and -8x are like terms.
you'll then have -12x = -8 - 6
calculate the difference of -8 and 6
you'll then have -12x = -14
you then divide the both sides by -12
getting the solution: x= 7/6

Mrs. Carter's famous peanut butter cookies call for 1 cup of peanut butter for every 1 2 of a cup of oil. Today, she wants to make a huge batch with 1 cup of oil. How much peanut butter should she use?
Answers
Answer:
2 cups of peanut butter
Step-by-step explanation:
Mrs. Carter's famous peanut butter cookies call for 1 cup of peanut butter for every 1/2 of a cup of oil. Today, she wants to make a huge batch with 1 cup of oil. How much peanut butter should she use?
From the above question:
1/2 cup of oil = 1 cup of peanut butter
1 cup of oil = x
Cross Multiply
1/2x = 1 × 1
x = 1 ÷ 1/2
x = 1 × 2/1
x = 2 cups of peanut butter.
Therefore, for huge batch with 1 cup of oil, she should use 2 cups of peanut butter.

Anna and Elsa are helping set up for the Christmas celebration at Magic Kingdom. They have to install 7 million lights for the annual display. It takes Elsa 14 days to set up the 7 million lights by herself and it takes Anna 11 days to set up the 7 million lights by herself. How long will it take them to do it together?
Answers
Answer:
If they work together, they will take 6.16 days.
Step-by-step explanation:
Elsa takes 14 days to complete the work.
So, 1 day work by Elsa is [tex]\frac{1}{14}[/tex]
Anna takes 11 days to complete the work.
So, 1 day work by Anna is [tex]\frac{1}{11}[/tex].
So, Let if they work together, it would take x number of days.
So, we can set up equation as
[tex]\frac{1}{14} +\frac{1}{11}=\frac{1}{x}[/tex]
Find LCD, which is 154.
[tex]\frac{11}{154} +\frac{14}{154} =\frac{1}{x}[/tex]
Simplify
[tex]\frac{25}{154} =\frac{1}{x}[/tex]
Cross multiply,
25x=154
Divide both sides by 25
x=6.16 days
If they work together, they will take 6.16 days.

Answers
2x + 5 = 5
2x = 0, x = 0
Y = 6(0) + 5, y = 5
Solution: x = 0, y = 5
Answer:
y=6x+5 →equation 1
y=4x+5 → equation 2
you can either substitute equation 1 in 2 or equation 2 in 1
substituting equation 1 in 2,
y = 4x + 5
6x + 5 = 4x + 5
6x - 4x = 5 - 5
2x = 0
x = 0/2
x = 0
substituting x = 0 in equation 1, (to get y)
y = 6x + 5
y = 6(0) + 5
y = 0 + 5
y = 5

The quotient when [tex]x^3-4x^2-8x+8[/tex] is divided by [tex]x+2[/tex] is [tex]x^2-6x+4[/tex] with no remainder, so x+2 is a factor of p(x).
Step-by-step explanation:
As the question suggests, there are two ways to solve this problem: long division (which can always be used to divide polynomials), and synthetic division (which can only be used when you are dividing by something of the form [tex](x-a)[/tex]. In this case, we may use synthetic division, since [tex]x+2[/tex] is equal to [tex]x-(-2)[/tex]. I will use synthetic division here as it is slightly faster than long division.
The -2 on the left represents that we are dividing by x-(-2), and the rest of the numbers in the top row are the coefficients of p(x): 1, -4, -8, and 8.
The first step in synthetic division is to being down the leading coefficient of the polynomial: in this case, the 1 (as indicated in red). Now, we multiply the 1 by -2. We get -2, which we place directly below the -4.
Next, we add directly down the column, (-4 + (-2) is equal to -6), and this answer is placed in the box below. We can continue this process, getting the coefficients 1, -6, 4, and 0 in the bottom row.
This is the answer: the quotient is [tex]x^2-6x+4[/tex], and the remainder is zero (which indicates that x+2 is a factor of p(x)).
--
Edit: long division
We may also solve this problem using long division (see the second image). The first step is to look at the leading coefficients: since [tex]x \times x^2[/tex] is equal to [tex]x^3[/tex], the first term in the quotient will be [tex]x^2[/tex]. Since [tex]x^2 \times (x+2)[/tex] is equal to [tex]x^3+2x^2[/tex], we must now subtract that from [tex]x^3-4x^2-8x+8[/tex].
We repeat the same process, as shown in the image. Since we eventually get to zero, the remainder is zero, and the polynomial at the top (x^2-6x+4) is the quotient.
I know this might be difficult to follow, so please comment if you have any questions.
