Which is the better buy: 1 liter of soda for $1, or 1 gallon of soda for $4? Justify your answer.
It is better to buy 1 liter of soda for $1 compare to 1 gallon of soda for $4 .
As given in the question,
1 liter of soda for $1 ____(1)
1 gallon of soda for $4
Relation between gallons and liters is given by:
1 gallon is equal to 3.785 liters
1 gallon of soda = $4
⇒ 3.785 liter = $4
⇒ 1 liter = $ ( 4 / 3.785 )
⇒ 1 liter = $ 1.056 _____(2)
From (1) and (2)
$1.056 > $1
It shows $1.056 is little bit higher than $1.
Therefore, it is better to buy 1 liter of soda for $1 compare to 1 gallon of soda for $4 .

A line goes through the points (-3, -2) and (3, 6). Write the equation of the line in Slope-Intercept form, y = mx + b.
LET US FIND THE GRADIENT
[tex]m = \frac{y2 - y1}{x2 - x1 \\ \\ } \\ = \frac{6 - ( - 2)}{(3 - ( - 3)} \\ = \frac{6 + 2}{3 + 3} \\ = \frac{8}{6} \\ m= \frac{4}{3} [/tex]
I WILL USE THE POINTS (-3,-2) TO GET THE VALUE OF C
[tex] - 2 = \frac{4}{3} ( - 3) + c \\ - 2 = - 4 + c \\ - 2 + 4 = c \\ c = 2[/tex]
THEREFORE THE EQUATION IS
[tex]y = \frac{4}{3} x + 2[/tex]

Answer:
y = 1/2x + 1/2
Step-by-step explanation:
I'm going to give me answer is gradient/slope form :
To work out the gradient we make a triangle from the line and do :
change in y / change in x
You should get 1/2
Now we have y=1/2x + c
to work out c we substitute a point from the line and solve for c :
Point (1 , 1)
1 = 1/2(1) + c
1 = 1/2 + c
c = 1/2
So our final answer is y = 1/2x + 1/2

The life expectancy of a new born kid increases at a rate of 1.5 years for every day the kid is alive during the first 60 days after being born. The expectancy reduces by 0.5 year for every day the kid is ill during these first 60 days. The initial life expectancy of a new born kid is 10 years. What is the life expectancy of a kid born on a Tuesday, after 37 days of being born (assume the kid is alive on the 37th day) if the kid falls ill on every Sunday?
The total life expectancy of the kid is 45.5 years.
rate of increase of life expectancy = 1.5 years per day
The rate of reduction of life expectancy = 0.5 years per day
37 days will mean ((7x5)+2), i.e., 5 complete weeks and 2 extra days.
Let the 2 extra days be Tuesday and Wednesday, now the 5 complete weeks will start from Thursday and after 37 days, the day will be Wednesday.
In this duration 5 Sundays will come on which the kid falls ill, so the reduction in life expectancy will be: 0.5 x 5= 2.5 years.
The remaining days will be: 37 - 5 = 32
So, the increase in life expectancy will be: 1.5 x 32= 48 years.
Thus, the total life expectancy of the kid is found to be : (48-2.5)years=45.5 years.
What are linear equations?
A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," where y and x are the variables.

Using the concept of the slope of a linear function, it is found that:
Pool A is filing up slower than Pool B because the slope of the graph for Pool A is less than that of the graph for Pool B.The slope of the graph tells you the unit rate in gallons per minute.What is a linear function?A linear function, in slope-intercept format, is modeled according to the following rule:
y = mx + b
In which:
The coefficient m is the slope of the function, which is the rate of change of the function, that is, the change in y divided by the change in x.The coefficient b is the y-intercept of the function, which is the the value of y when the function crosses the x-axis(x = 0).For this problem, we have that Pool B starts with significantly less water than Pool A, but their volumes get closer, meaning that Pool B fills faster and has a higher slope, that is, it fills more gallons per minute into the pool.

0, 2 + StartRoot 3 EndRoot, 2 minus i StartRoot 3 EndRoot
All solutions to the cubic equation, 4•x³ + 16•x² + 28•x = 0, are presented as follows;
0, -2 + i•√(3), -2 - i•√(3), which is the option;
0, negative 2 + i StartRoot 3 EndRoot, negative 2 minus i StartRoot 3 EndRootWhat are the solutions to a cubic function?The solutions of a cubic function are given by the values at which the graph intersects the horizontal axis.
First Part
The graph showing the shaded region of the inequality is left out
Second part;
The given equation can be presented as follows;
4•x³ + 16•x² + 28•x = 0
Required;
To find all the solutions of the equation
Solution;
The solutions of the equation are given by the locations on the graph where the equation intersects the x–axis, which are therefore, the points where the function is equal to 0
The equation 4•x³ + 16•x² + 28•x = 0 can therefore be used to find the solution as follows;
4•x³ + 16•x² + 28•x = 0
x•(4•x² + 16•x + 28) = 0
x•(4)•(x² + 4•x + 7) = 0
x•(x² + 4•x + 7) = 0 ÷ (4) = 0
x•(x² + 4•x + 7) = 0
Which by the multiplicative identity of 0, gives;
x = 0 or x² + 4•x + 7 = 0Therefore;
x = 0 is a solution to the equation
The other solutions are found from the quadratic equation, x² + 4•x + 7 = 0, using the quadratic formula that gives the solution to the general quadratic equation, a•x² + b•x + c = 0, as follows;
[tex] \displaystyle{x = \frac{ - b \pm \sqrt{ {b}^{2} - 4 \times a \times c } }{2 \times a }}[/tex]
Comparing the general form of the quadratic equation to the quadratic equation from the question;
a•x² + b•x + c = 0
x² + 4•x + 7 = 0
Gives;
a = 1
b = 4
c = 7
Plugging in the above values of a, b, and c, we get;
[tex] \displaystyle{x = \frac{ - 4 \pm \sqrt{ {4}^{2} - 4 \times 1 \times 7 } }{2 \times 1} = \frac{ - 4 \pm 2 \cdot\sqrt{ - 3} }{2} }[/tex]
Which gives;
x = -2 ± √(-3) = -2 ± i•√(3)
The other solutions are therefore;
x = -2 + i•√(3) and x = -2 - i•√(3)The solutions of the equation, 4•x³ + 16•x² + 28•x = 0, are therefore;
x = 0, x = -2+i•√(3), and x = -2 - i•√(3)

Company A charges $20.40 monthly for up to 3 gigabytes of data and $9.80 per additional gigabyte. Company B charges $18.60 monthly for up to 3 gigabytes of data and $10.10 per additional gigabyte. For what number of additional gigabytes would the two companies charge the same amount?
_________ additional gigabytes of data
Considering the definition of an equation and the way to solve it, for 6 additional gigabytes of data the two companies would charge the same amount.
Definition of equationAn equation is the equality existing between two algebraic expressions connected through the equals sign in which one or more unknown values appear.
The solution of a equation means determining the value that satisfies it. To solve an equation, keep in mind:
When a value that is adding, when passing to the other member of the equation, it will subtract.If a value you are subtracting goes to the other side of the equation by adding.When a value you are dividing goes to another side of the equation, it will multiply whatever is on the other side.If a value is multiplying it passes to the other side of the equation, it will pass by dividing everything on the other side.This caseBeing "x" the number of miles driven, and knowing that:
Company A charges $20.40 monthly for up to 3 gigabytes of data and $9.80 per additional gigabyte. → Price of company A= 20.40 +9.80xCompany B charges $18.60 monthly for up to 3 gigabytes of data and $10.10 per additional gigabyte.→ Price of company B= 18.60 +10.10xIf the price charged by each company is the same, the equation is:
Price of company A= Price of company B
20.40 +9.80x= 18.60 +10.10x
Solving:
20.40 - 18.60= 10.10x - 9.80x
1.8= 0.3x
1.8 ÷ 0.3= x
6= x
Finally, for 6 of additional gigabytes the two companies would charge the same amount.
