Opciones:
A) (-8, -7)
B) (0, 1)
C) (0, 2)
D) (3, 4)
Responder:
(0, 2)
Explicación paso a paso:
Dado :
y = (x + 1)
Para probar qué puntos no pertenecen; aplicamos la ecuación a las opciones dadas para ver cuál de las opciones no se ajusta a la ecuación:
(x = -8, y = - 7)
y = (x + 1)
y = - 8 + 1
y = - 7
(x = 0, y = 1)
y = 0 + 1
y = 1
(x = 0, y = 2)
y = 0 + 1
y = 1
El punto (0, 2) no pertenece
(x = 3, y = 4)
y = 3 + 1
y = 4
The points (0,2) do not belong to the given equation y = x + 1.
What is a linear equation?A linear equation is an equation in which the highest power of the variable is always 1. The standard form of a linear equation in one variable is of the form Ax + B = 0.
The given equation is y = x + 1
To prove which points do not satisfy the given equation, we apply the given option to the equation.
1. (x = -8, y = - 7)
y = (x + 1)
y = - 8 + 1
y = - 7
Hence, The given points belong to the equation.
2. (x = 0, y = 1)
y = 0 + 1
y = 1
Hence, The given points belong to the equation.
3. (x = 0, y = 2)
y = 0 + 1
y = 1
Hence, The given points don't belong to the equation.
4. (x = 3, y = 4)
y = 3 + 1
y = 4
Hence, The given points belong to the equation.
Therefore, option 3 is correct in that point(0,2) does not belong to the given equation.

How do I express the letters in bracket as the subject of the formula ?
especially the 1/2 power is new and unfamiliar to me.
Answer:
[tex]n = 144m^2 - 1[/tex]
Step-by-step explanation:
__________________________________________________________
FACTS TO KNOW BEFORE SOLVING :-
Let x be a number. ⇒ [tex]x^{\frac{1}{2}}[/tex] can also be written as [tex]\sqrt{x}[/tex].To make any variable the subject of any formula , we need to isolate it.__________________________________________________________
According to the question ,
[tex]3m = \frac{(n + 1)^{\frac{1}{2} }}{4}[/tex]
Lets multiply both the sides by 4.
[tex]=> \frac{(n + 1)^{\frac{1}{2} }}{4} \times 4 = 3m \times 4[/tex]
[tex]=> (n + 1)^{\frac{1}{2} } = 12m[/tex]
It can be also written as :-
[tex]=> \sqrt{(n + 1)} = 12m[/tex]
Lets square both the sides.
[tex]=> [\sqrt{(n + 1)} ]^{2} = (12m)^{2}[/tex]
[tex]=> n + 1 =144m^2[/tex]
[tex]=> n = 144m^2 - 1[/tex]

Answer:
the answer is [tex]\sqrt 8[/tex], or 2.83 cm.
Step-by-step explanation:
You need to use the pythagorean theorem to solve this. It states that [tex]a^{2} + b^{2} = c^{2}[/tex]. a is one leg of the triangle, b is the other leg, and c is the hypotenuse (the slanted line that connects them). We need to do [tex]2^{2}[/tex] to find this. Since [tex]2^{2}[/tex] is 4, we know both legs are 4 [tex]cm^{2}[/tex]. 4 + 4 = 8. Since c is squared, we need to find the square root of 8, or just leave it as is. the final answer is [tex]\sqrt{8}[/tex], or 2.83. Hope this helped! :]

Step-by-step explanation:
Many large cities use taxes on entertainment tickets to pay for improvements to public facilities, like stadiums, arenas, and concert venues. A city council proposal would increase the current ticket tax in order to raise funds for a new public concert hall. Council representatives plan to conduct a survey outside of a large concert in the summer and ask selected adults if they would support an increase in the ticket tax to pay for the new concert hall. Which type of bias will most likely affect the survey results? This is response bias because it is likely that many who respond will not provide a truthful opinion of the ticket tax. This is undercoverage bias because only those attending the concert will have an opportunity to register an opinion. This is nonresponse bias because many who are asked about the ticket tax may choose to not provide a response. This is voluntary response bias because many vocal supporters of the ticket tax may demand to register their opinion.
Answer:
This is undercoverage bias because only those attending the concert will have an opportunity to register an opinion.
Step-by-step explanation:
Undercoverage bias occurs when the sample chosen for a research is not representative of the entire population. Most times when research involving surveys to obtain the opinions of people on a subject matter, the entire population affected by the issue cannot be surveyed. A sample that represents the true population can be used for this research.
In the survey above, the sample that was surveyed was not representative of the entire population of citizens paying taxes on entertainment tickets. The selection process does not represent the true population.

The cost c in dollars of manufacturing x bicycles at a production plant is given by th function shown below C(x)=5x^2-1000x+63,500. How many bicycles must be manufactured to minimize the cost
Answer:
100 bicycle
Step-by-step explanation:
Given the cost c in dollars of manufacturing x bicycles at a production plant expressed as C(x)=5x^2-1000x+63,500.
x is the number of bikes
To minimize the cost, dC/dx = 0
dC/dx = 10x - 1000
Since dC/dx = 0
0 = 10x - 1000
-10x = -1000
x = 1000/10
x = 100
Hence the number of bicycles that must be manufactured to minimize the cost is 100 bicycle
Delaney is saving money in an account that offers 9% simple interest. She deposits 2000 from her grandmother into the account and makes no additional deposits or withdraws. How many years will it take to grow to 4,700
Answer:
15years
Step-by-step explanation:
Given data
Rate= 9%
Principal= $2000
Final amount= $4700
The simple interest formula is given as
A= P(1+rt)
Substitute
4700=2000(1+0.09*t)
4700= 2000+ 180t
4700-2000= 180t
2700=180t
t= 2700/180
t= 15 years
Hence the time is 15years
marty has 1 1/3 jugs of apple juice. he uses 3/4 of the juice to make freeze pops. what fraction amount of a jus doe marty have?
Answer:
He has 1/3 of a jug left.
Step-by-step explanation:
He starts with 1 1/3 jugs.
He uses 3/4 of 1 1/3 jugs.
A full amount is 1 or 4/4. If he uses 3/4, he has 1/4 left since
1 - 3/4 = 4/4 - 3/4 = 1/4
That means he has 1/4 of 1 1/3 jugs left.
We need to multiply 1/4 by 1 1/3.
1/4 * 1 1/3 =
= 1/4 * 4/3
= 4/12
= 1/3
Answer: He has 1/3 of a jug left.

For volunteers picked up letter from the park Dominic you collect and 15 for your pieces a litter than Sarah Sarah collect the 12 more pieces in piper piper collected 1/4 as many pieces of litter as Vaughn Vaughn has collected nine more pieces of wood or than everyone else combine the X represent the number of pieces of litter Vaughn Collection
So many confusing details. So, I rephrase the question as:
Four volunteers picked up litters from the park.
Dominic collect 15 pieces less than Sarah. Sarah collects 12 more pieces than Piper. Piper collected 1/4 as many pieces of letter as Vaughn. Vaughn has collected nine more pieces of letter than everyone else combined. Let x represent the number of pieces of litter in Vaughn's Collection. Find x
Answer:
[tex]x = 72[/tex]
Step-by-step explanation:
Let:
[tex]D = Dominic;\ \ S = Sarah;\ \ P = Piper;\ \ V = Vaughn[/tex]
From the [rephrased] question, we have:
[tex]D = S - 15[/tex]
[tex]S = 12 + P[/tex]
[tex]P = \frac{1}{4}V[/tex]
[tex]V = 9 + D + S + P[/tex]
Substitute [tex]S = 12 + P[/tex] in [tex]D = S - 15[/tex]
[tex]D = 12 + P - 15[/tex]
[tex]D = P+12 - 15[/tex]
[tex]D = P-3[/tex]
Make V the subject in [tex]P = \frac{1}{4}V[/tex]
[tex]V = 4P[/tex]
Substitute: [tex]V = 4P[/tex], [tex]D = P-3[/tex] and [tex]S = 12 + P[/tex] in [tex]V = 9 + D + S + P[/tex]
[tex]4P= 9 + P - 3 + 12 + P +P[/tex]
Collect like terms
[tex]4P - P -P-P= 9 - 3 + 12[/tex]
[tex]P= 18[/tex]
Substitute [tex]P= 18[/tex] in [tex]S = 12 + P[/tex]
[tex]S = 12 +18[/tex]
[tex]S = 30[/tex]
Substitute [tex]S = 30[/tex] in [tex]D = S - 15[/tex]
[tex]D = 30 - 15[/tex]
[tex]D =15[/tex]
Substitute [tex]D =15[/tex], [tex]S = 30[/tex] and [tex]P= 18[/tex] in [tex]V = 9 + D + S + P[/tex]
[tex]V = 9 + 15 + 30 + 18[/tex]
[tex]V = 72[/tex]
x represents the number collected by Vaughan.
So:
[tex]x = 72[/tex]
