6+2y=8=y
We move all terms to the left:
6+2y-(8)=0
We add all the numbers together, and all the variables
2y-2=0
We move all terms containing y to the left, all other terms to the right
2y=2
y=2/2
y=1
For P(x) = 2x^4 – 5x^3+x-10, use synthetic substitution to evaluate P(-2). P(1), and P(2).
Answer:
P(-2) = 2(-2^4) - 5(-2^3) + (-2) -10
= 2(16) - 5(-8) + (-2) - 10
= 32+40-2-10
= 60
P(1) = 2(1^4) - 4(1^3) + (1) - 10
= 2 - 4 + 1 - 10
= -11
P(2). = 2(2^4) - 5(2^3) + (2) - 10
= 2(16) - 5(8) + 2 - 20
= 32-40+2-10
= -20

Why might the triangulation method not always produce an exact point (other than any measurement errors)
Answer:
The triangulation method might not always produce an exact point (other than any measurement errors) because:
The method uses different data sources, researchers, and theories or perspectives.
Step-by-step explanation:
Research Triangulation uses multiple methods, data sources, different investigators, and varied theories for the purpose of developing a more comprehensive understanding of the underlying situations. Triangulation validates the qualitative research by obtaining information from different sources, investigators, viewpoints, or methods.
Which equation will solve the following word problem? One small pitcher and one large pitcher can hold 12 cups of water. If the large pitcher is twice the size of the small pitcher, how much does the small pitcher hold?

Ann had 48 fliers to post around town. Last week, she posted 2/3 of them. This week, she posted 3/8 of the remaining fliers. How many fliers has she still not posted?
Answer:
Ann had 48 fliers to post around town
Last week, she posted 2/3 of them
[tex]48 \times \frac{2}{3} = 32 \\ [/tex]
Therefore, she should posted 32 fliers
This week, she posted 3/8 of the remaining fliers
[tex]48 \times \frac{3}{8} = 18 \\ [/tex]
Therefore, she should posted 18 fliers
Total fliers she should post are (32+18)=50 fliers
She still did not post (50-48)= 2 fliers
2 fliers is the right answer.hgfgderwasgtfvuyibhnojpmk[p

Leah plans to purchase merchandise from a department store that is valued at $100. She will use $20 in-store bucks that she has earned
plus a 30% discount coupon to reduce her final cost. What is the final cost of the items (before tax) if the $20 store bucks are applied before
the 30% discount?
The final cost of the items (before tax) if the $20 store bucks are applied before the 30% discount is $76.
The discount of 30% will be applied on $80 ($100 - $20), resulting to a discount of of $24 ($80 * 30%).
This discount is subtracted from the total value of the merchandise to get the final cost as $76 ($100 - $24).
Thus, the final cost to Leah to purchase the merchandise from the department store is $76.

Using the remainder theorem see if (x-2) and (x+5) are factors of the polynomial
X^2+3x-10
Answer:
See explanations below
Step-by-step explanation:
Given the polynomial function
P(x) = X^2+3x-10
To check whether x-2 and x+5 are factor, we will find x and then show that P(x) = 0
For x-2
x - 2 = 0
x =2
P(2) = 2²+3(2)-10
P(2) = 4+6 -10
P(2) = 10-10
P(2) = 0
Since the remainder is zero, hence x-2 is a factor of the polynomial
Similarly for x+5;
x+5 = 0
x = -5
P(-5) = (-5)²+3(-5)-10
P(-5) = 25-15-10
P(-5) = 10-10
P(-5) = 0
This also shows that x+5 is a factor

Gideon is filling a container with sand. How much sand will fit in the container
Answer:
418cm³
Step-by-step explanation:
volume of cuboid=l×b×h=11×2×19=418c³
Answer:
418 square centimeters.
Step-by-step explanation:
Since the formula for volume is length times width times height, you would have to multiply 11 (length) times 2 (width) first, and you would get 22. Next, you have to multiply 22 with the height (19). After you do this you will get your final answer which is 418 square centimeters.

Find the least common denominator of
x2 - 4x – 21
and
x² - 4
Answer:
LCD = (x - 7)(x + 3)(x + 2)(x - 2)
Step-by-step explanation:
First, we factor each polynomial.
x^2 - 4x - 21 = (x - 7)(x + 3)
x^2 - 4 = (x + 2)(x - 2)
There are 4 different factors and none are in common, so the LCD is the product of all the factors.
LCD = (x - 7)(x + 3)(x + 2)(x - 2)
Answer:
(x+3)(x-7) & (x+2)(x-2)

Which set of shapes can be arranged in 6 equal groups, with no shapes left
over?
The set of shapes that can be arranged in 6 equal groups is the first set or the set of triangles.
What does it mean to arrange with no shapes left over?This task requires you to arrange or divide the shapes in equal groups of 6 and once the shapes are divided there can not be any shape leftover. Let's look at some examples:
20 apples divided between 5 people = 4 apples4 apples x 5 people = 20 (there are no apples leftover)20 apples divided between 6 people = 3 apples3 apples x 6 people = 18 apples ( there are 2 apples left over)What set does not leave shapes leftover?The only set in which this occurs is the triangle set. This is because there are 12 triangles and 6 is a divisor of 12.
12 / 6 = 26 x 2 = 12Note: This question is incomplete, below I attach the missing part.
