A) 4 - 311 - 49^2
B) 34r – 6 + 28r^2
C) 26r - 6 + 287^2

Solve this system of equations 2x+4y=-6 x=y-12
Answer:
Step-by-step explanation:
2(y-12) +4y = -6
2y -24 +4y = -6
6y -24 = -6
6y= -18
y = -3
x = -3 - 12
x = - 15
x = -15
y = -3
Answer:
x=-9, y=3
Step-by-step explanation:
2(-9)=-18 4(3)=12 -18+12=-6 so, -6=-6, it is determined true
-9=3-12 3-12=-9 so, -9=-9, it is determined true

Step-by-step explanation:
Una poblacion es atacada por una epidemia de gripe sea N(t)= numero de personas enfermas al tiempo t. En dias la epidemia inicio en N(0)= 50. Un matematico determina que la gripe se extiende a razón de f'(t)= 120t- 3t^2 personas por día. Determina
a) La función original que describe el comportamiento de la epidemia. (Aplica los mismos pasos explicados anteriormente.
b) ¿Cuántos enfermos habrán después de 15 días si no se controla la epidemia?
Answer:
Habrán 10175 enfermos a los 15 dias.
Step-by-step explanation:
La tasa de cambio de la población enferma por la epidemia de gripe es:
[tex]N'(t)=120t-3t^2[/tex]
Donde t es el tiempo en dias, y se sabe que la epidemia inició en N(0)=50.
a)
Para encontrar la función original que describe el comportamiento de la epidemia, debemos integrar la función:
[tex]N(t)=\int N'(t)dt[/tex]
[tex]N(t)=\int (120t-3t^2)dt[/tex]
Integrando:
[tex]\displaystyle N(t)=120\frac{t^2}{2}-3\frac{t^3}{3}+C[/tex]
Simplificando:
[tex]\displaystyle N(t)=60t^2-t^3+C[/tex]
Para determinar el valor de C, usamos la condición inicial N(0)=50:
[tex]\displaystyle 50=60(0)^2-(0)^3+C[/tex]
Se tiene que C=50, y la función queda determinada como:
[tex]\displaystyle N(t)=60t^2-t^3+50[/tex]
b) El número de enfermos a los t=15 dias se determina substituyendo el valor en la función original:
[tex]\displaystyle N(15)=60(15)^2-(15)^3+50[/tex]
Calculando:
[tex]N(15)=13500-3375+50=10175[/tex]
Habrán 10175 enfermos a los 15 dias.

A 16 ounce box of cereal costs $4.00. How many cents per ounce does cereal cost?
Answer:
25cents/ounce
Step-by-step explanation:
Given parameters:
Ounce of cereal box = 16ounces
Cost = $4
Unknown:
cents per ounce = ?
Solution:
To solve this problem;
Convert the dollar bill to cents
$1 = 100cents
$4 will give us 4 x 100 = 400cents
Cost in cents per ounce= [tex]\frac{400}{16}[/tex] = 25cents/ounce

Priya, Han, Lin, and Diego are all on a camping trip with their families. The first morning, Priya and Han make oatmeal for the group. The instructions for a large batch say, “Bring 15 cups of water to a boil, and then add 6 cups of oats.”
Priya says, “The ratio of the cups of oats to the cups of water is
6:15
. That’s 0.4 cups of oats per cup of water.”
Han says, “The ratio of the cups of water to the cups of oats is
15:6
. That’s 2.5 cups of water per cup of oats.”
Who is correct? Explain your reasoning. If you get stuck, consider using the table.
Answer:
Han is because the cups of water is 15 ad oat is 6.
Step-by-step explanation:
Answer:
Han is correct

At a local high school, 30% of the students are on a school sports team, 25% take at least one Advanced Placement (AP) class, and
10% are on a sports team and take at least one AP class. If a student was randomly selected from this school, what is the
probability that the student is on a sports team or takes at least one AP class?
Plz hurryyyy
0.45 will be the probability that the student is on a sports team or takes at least one AP class
What is probability?Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.
Given, At a local high school, 30% of the students are on a school sports team, 25% take at least one Advanced Placement (AP) class,
So,
Probability of Getting a student from a sports TeamP(A) = 0.3
Probability of Getting a student from an AP class P(B)= 0.25
Since 10% are on a sports team and take at least one AP class.
P(A ∩ B ) = 0.10
Thus,
P(A∪B) = P(A) + P(B) - P(A ∩ B )
P(A∪B) = 0.30 + 0.25 - 0.10
P(A∪B) = 0.45
therefore, the probability that the student is on a sports team or takes at least one AP class will be 0.45.

5n(-7n)+6
How do you solve this
Answer:
-35n+6
Step-by-step explanation:
5n(-7n)+6
Okay so there is a term in front of another term in parentheses
This let's us know that we are going to distribute (multiply)
5n × -7n = -35n^2
The reason it's -35 it's because a positive times a negative is a negative
the reason it's n^2 it's because n × n = n^2
Now we can't forget the positive 6!
-35n + 6 is your answer
The reason we don't add the 6 to the -35n is because they are not like terms so therefore we cannot do anything further
The 6 does not have an n attached to it so we leave as it it
The table below shows that the number of miles driven by Lily is directly proportional to the number of gallons she used. Gallons Used Miles Driven 37 754.8 47 958.8 50 1020 What is the constant of proportionality between the number of miles driven and the number of gallons used?
Answer:
20.4
Step-by-step explanation:
Constant of proportionality, k, is given as [tex] \frac{y}{x} [/tex].
Given that number of miles driven by Lily is directly proportional to the number of gallons she used, therefore the constant of proportionality between the number of miles driven and the number of gallons used can be determined by using any given pair from the table of values.
Using, (50, 1020),
constant of proportionality (k) = [tex] \frac{1020}{50} = 20.4 [/tex].
The constant of proportionality is 20.4 miles per gallon.
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the slope of the line and b is the y intercept.
Let y represent the distance driven in miles for x galloons.
From the table, using the points (37, 754.8) and (50, 1020):
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-754.8=\frac{1020-754.8}{50-37}(x-37)\\\\y-754.8=20.4(x-37)\\\\y=20.4x[/tex]
Therefore the constant of proportionality is 20.4 miles per gallon.
