Which polynomial is in standardare form?
Answers
Answer:
[tex]x^5y^5-3xy-11x^2y^2+12[/tex]
Step-by-step explanation:
What does a polynomial being in standard form mean?
It means that the terms are ordered from highest degree to lowest.
In this case, it would be the 3rd option ([tex]x^5y^5-3xy-11x^2y^2+12[/tex]) since it's the only option where all of the terms have a descending order of degrees.

Answers
Answer:
y-2=3(x+9)
Step-by-step explanation:
ok, first of all, parallel lines have the same slope.
point slope form is y-y1=m(x-x1) (m is the slope)
so we know the slope is 3
and the point is (-9,2)
plug everything in
y-2=3(x+9)

Answers
Answer: y = -5x + 6
Step-by-step explanation:
(1, 1), (2, -4), and (0, 6) are the points on your graph
slope (m) = (y2 - y1) / (x2 - x1)
m = -4 - 1 / 2 - 1 = -5/1 = -5
y = mx + b
y = -5x + b
(0,6) would be your y-intercept because it is on the y-axis
in y = mx + b, b is always the y-intercept
y = -5x + 6
* you can also plug (1, 1) or (2, -4) into y = -5x + b and solve for b
Write an
equation given the following: m = 1, y-int = 2 *
2) m=0 y-int = 2
3) m=-1 y-int = 8
4) m= 5 y-int =0

kim buys pet food in 1.5kg packs, het pet needs 0.8kg of food each week. She wants to have enough food for the next 14 weeks. She already has two 1.5kg packs. Work out the smallest number of packs she needs to buy.
Answers
========================================================
Explanation:
"She already has two 1.5kg packs" means she already has 2*1.5 = 3 kg of food.
The statements "her pet needs 0.8 kg of food each week" and "She wants to have enough food for the next 14 weeks" tell us that she needs 0.8*14 = 11.2 kg of food total.
--------------------------------
Let,
x = number of packs she needs to buy
1 pack = 1.5 kg of food
x packs = 1.5x kg of food
Add on the 3 kg of food she already has to get 1.5x+3
The expression 1.5x+3 represents how much food she'll have total after buying x packs.
Set this equal to 11.2 and solve for x
1.5x+3 = 11.2
1.5x+3-3 = 11.2-3 ... subtracting 3 from both sides
1.5x = 8.2
1.5x/(1.5) = 8.2/(1.5) .... dividing both sides by 1.5
x = 5.4667 approximately
x = 6 rounding up to the nearest whole number
We round up instead of down.
This is because if x = 5, then,
1.5*x+3 = 1.5*5+3 = 7.5+3 = 10.5, but this is less than 11.2
However, if x = 6, then,
1.5*x+3 = 1.5*6+3 = 9+3 = 12 which clears the hurdle of 11.2
So this means buying 6 packages of food is the smallest amount needed to ensure her pet has enough food for the next 14 weeks.
Kim needs to buy 6 packs of pet food.
What is Unitary Method?Unitary method is a mathematical technique used to solve problems involving proportions. It involves finding the value of one unit and then using that to find the value of other units. In other words, it is a method in which we find the value of one unit and then use it to calculate the value of a given number of units.
Kim already has 2 packs of 1.5 kg = 3 kg of pet food.
Kim needs 0.8 kg of pet food each week for 14 weeks
= 0.8 x 14
= 11.2 kg.
So, Kim needs to buy an additional
= 11.2 kg - 3 kg
= 8.2 kg of pet food.
Each pack of pet food is 1.5 kg, so Kim needs to buy 8.2 kg / 1.5 kg per pack = 5.47 packs.
Since Kim cannot buy a fraction of a pack, she needs to round up to the next whole number of packs.
Therefore, Kim needs to buy 6 packs of pet food.

Answers
The GCF of "8bc" and "17abc" would be "bc" which is determined by prime factorization.
What is Prime Factorization?Prime Factorization is defined as any number that may be expressed as a product of prime numbers that has been said to be prime factorized. Any integer with exactly two factors 1 and the number itself. is said to be a prime number.
We have to determine the GCF of 8bc and 17abc
We need to write 8bc and 7abc as the product of their prime factors
Prime factorization of the given numbers:
⇒ 8bc = 2 × 2 × 2 × b × c
Here 8 is 2 × 2 × 2
⇒ 7abc = 7 × a × b × c
GCF (8bc, 7abc) :
= b × c
= bc
Therefore, the GCF of "8bc" and "17abc" would be "bc" which is determined by prime factorization.

X+40+4x-5=6x+20 can you please help me find the answer I need it asp
Answers
Answer:
Step-by-step explanation:
x+40+4x-5=6x+20
So, we first add the numbers in terms of x, then we add the numbers.
5x+40-5=6x+20
5x+35=6x+20
Then, we subtract 20 from each side.
5x+35(-20)=6x+20(-20)
5x+15=6x
Then, we subtract 5x from each side
15=6x-5x
15=1x
15=x
So, x equals 15. Hope this helps :)
