The boiling point of water is 100 degrees Celsius. Write an inequality to represent a pot of water that is not boiling.
Answer: x < 100 , where x = the temperature of a pot of water ( in degrees Celsius).
Step-by-step explanation:
The boiling point of water is 100 degrees Celsius.
The temperature of water that is not boiling must be less than 100 degrees Celsius.
Let x be the temperature of a pot of water ( in degrees Celsius).
Then, as per given,
x < 100
hence, the inequality to represent a pot of water that is not boiling.:

1. John’s age is three times that of his sister. When you add John’s age to his sister's age, you get 36. How old are John and his sister?
(a) Write an equation that represents the situation. (1 point)
(b) Solve the equation from Part (a). Show your work. (3 points)
Answer:
Part A: Write an equation.
If the present age is y, then n times the present age = ny.
If the present age is x, then age n years later/hence = x + n.
If the present age is x, then age n years ago = x – n.
The ages in a ratio a: b will be ax and bx.
Part B: Solve the equation.
John’s age =
John’s sister’s age =
Answer:
sister = 6 years
John=18 years
Step-by-step explanation:
A(S) + 12 = 3 * A(S), subtracting A(S) from both sides one gets 12 = 2 * A(S). Now dividing both sides by 2 we get A(S) = 12/2 = 6 . Therefore, the age of the sister is 6 years when her brother John is three times as old, that is 18 years.

A Web music store offers two versions of a popular song. The size of the standard version is 2.8 megabytes (MB). The size of the high-quality version is 4.1
MB. Yesterday, there were 1600 downloads of the song, for a total download size of 5624 MB. How many downloads of the high-quality version were
there?
Number of high-quality version downloads:
Answer:
Number of high quality version downloads = 880
Step-by-step explanation:
Let,
x be the number of standard version songs downloaded
y be the number of high quality version songs downloaded
According to given statement,
x+y=1600 Eqn 1
2.8x+4.1y=5624 Eqn 2
Multiplying Eqn 1 by 2.8 to eliminate x
2.8(x+y=1600)
2.8x+2.8y=4480 Eqn 3
Subtracting Eqn 3 from Eqn 2
(2.8x+4.1y)-(2.8x+2.8y)=5624-4480
2.8x+4.1y-2.8x-2.8y=1144
1.3y=1144
Dividing both sides by 1.3
[tex]\frac{1.3y}{1.3}=\frac{1144}{1.3}\\y=880[/tex]
Hence,
Number of high quality version downloads = 880

By the Exterior Angle Theorem, we know that the exterior angle is equal to the sum of the two opposite interior angles.
(2x+3)+25=3x-17 [combine like terms]
2x+28=3x-17 [subtract both sides by 2x]
28=x-17 [add both sides by 17]
x=45
Now, we know that the answer is A.

The Graph shows the total?!
What is the answer ???????????????
Answer:
(2, - 1 )
Step-by-step explanation:
Given the 2 equations
y = 4x - 9 → (1)
y = x - 3 → (2)
Substitute y = 4x - 9 into (2)
4x - 9 = x - 3 ( subtract x from both sides )
3x - 9 = - 3 ( add 9 to both sides )
3x = 6 ( divide both sides by 3 )
x = 2
Substitute x = 2 into either of the 2 equations for y
Substituting into (2)
y = 2 - 3 = - 1
solution is (2, - 1 )

Three salesmen work for the same company, selling the same product. And, although they are all paid on a weekly basis, each salesman earns his paycheck differently. Salesman A works strictly on commission. He earns $65 per sale, with a maximum weekly commission of $1,300. Salesman B earns a weekly base salary of $300, plus a commission of $40 per sale. There are no limits on the amount of commission he can earn. Salesman C does not earn any commission. His weekly salary is $900.
The weekly paycheck amount for each salesman, p, is a function of the number of sales, s, they had in that week.
Is the function representing the weekly paycheck amount of Salesman A a proportional relationship? Use complete sentences to explain your reasoning.
Is the function representing the weekly paycheck amount of Salesman B a proportional relationship? Use complete sentences to explain your reasoning.
Is the function representing the weekly paycheck amount of Salesman C a proportional relationship? Use complete sentences to explain your reasoning.
Answer:
See below
Step-by-step explanation:
Proportional relationship formula:y = kxAs per given we have:
Salesman A
p(s) = 65s (p = $1300 maximum)This is a proportional relationship, $65 per each sale. But this is restricted to 20 sales.Answer is yes (ignoring the restriction)Salesman B
p(s) = 40s + 300This is a linear but not proportional relationshipAnswer is noSalesman C
p(s) = 900There is no relationship between sales number and weekly earning as it is a fixed salaryAnswer is noA customer wants to purchase a sweater from a store.

Solve this system of equations.
3x + 4y = 36
y=-2 +8
Answer:
( X, y [tex] = (x.y) ( - \frac{4?}{?3} = 10)[/tex]Standard form [tex]3 \times + 4y = 36 \\ y = 10[/tex]Write an equation in slope intercept form of the line that passes through (-2,10) and (1,1).
Answer:
(-2,10)=x1,y1
(1,1)=x2,y2
we have,
(y-y1)=(y2-y1)/(x2,x1)[(x-x1)]
(y-10)=(1-10)/(1+2)[x+2]
y-10=-9/3(x+2)
y-10=-3(x+2)
y-10=3x+6
y=3x+16
Answer:
y = -3x + 4Step-by-step explanation:
The slope of a line passing through two points: (x₂, y₂) and (x₁, y₁) is:
[tex]\bold{m=\dfrac{y_2-y_1}{x_2-x_1}}[/tex]
(-2, 10) ⇒ x₁ = -2, y₁ = 10
(1, 1) ⇒ x₂ = 1, y₂ = 1
So:
[tex]\bold{m=\dfrac{1-10}{1+2}=\dfrac{-9}{3}=-3}[/tex]
The point-slope form of equation of line is y - y₀ = m(x - x₀)
We can pick any of given poins, so:
x₀ = 1, y₀ = 1 and m = -3
y - 1 = -3(x - 1)
y = -3x + 3 + 1
y = -3x + 4 ← slope intercept form of the line
