Step-by-step explanation:
The total cost, C, for running an advertisement in a local newspaper, The Free Press, is made up of an initial cost of $12 plus a charge of $5 per day. A rival newspaper, The Banner, is currently running a special on advertisements at $8 per day with no initial cost.
a) Write an equation representing the cost in The Free Press.
b) Write an equation representing the cost in The Banner.
c) For each newspaper, create a table of values.
d) Use Geometer’s Sketchpad to graph each cost on the same set of coordinate axes.
e) Which newspaper would you use for an ad that ran 1 day?
f) Which newspaper would you use for an ad that ran 12 days?
The equation representing the cost in The Free Press is 12 + 5d.
How to depict the equation?The equation representing the cost in The Free Press will be:
= 12 + (5 × d)
= 12 + 5d
The equation representing the cost in The Banner will be:
= 8 × d
= 8d
The table of value for Free Press will be:
1st day = 12
2nd day = 17
3rd day = 22
4th day = 27
5th day = 32
The table of value for the Banner will be:
1st day = 8
2nd day = 16
3rd day = 24
4th day = 32
5th day = 40
The newspaper that will be used to run the advertisement for the first day is Free Press since it's cheaper.
The newspaper that will be used to run the advertisement for twelve days will be:
Free press = 12 + 5d
= 12 + 5(12)
= 12 + 60 = 72
The banner = 8d = 8 × 12 = 96
Therefore, for 12 days, Free Press is cheaper.

You are able to walk uphill at a speed of 2 miles per hour and downhill at a speed of 3 miles per hour. What does the graph represent?
Using a piece-wise function, the representation of the graph is given as follows:
Walking uphill for 3 hours and downhill for 1 hour.
What is a piece-wise function?A piece-wise function is a function that has multiple definitions, depending on the input.
In this problem, we have that:
For the first 3 hours, the slope is of 2 miles per hour, equivalent to walking uphill.For the final hour, the slope is of 3 miles per hour, equivalent to walking downhill.Hence the meaning of the graph is:
Walking uphill for 3 hours and downhill for 1 hour.

[tex]y - 0 = -1.5(x -0)[/tex]
[tex]y = -1.5x[/tex]
Answer:
y = (-3/2)x
Step-by-step explanation:
I am going to answer this question in slope-intercept form, which is y = mx + b (m is the slope, b is the y-intercept). The question already gives us the y-intercept, or the point at which the graph crosses the y-axis. It is (0, 0). Now, all we have to do is find the slope, which we can do using the following formula:
[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]
In this formula, (x1, y1) and (x2, y2) are two points that are given to us [the first point is (0,0) and the second point is (2,-3). We can solve for the slope by plugging in:
[tex]m=\frac{-3-0}{2-0}=\frac{-3}{2}[/tex]
Now that we have m and b, we can plug into slope-intercept form to get our equation: y = (-3/2)x + 0 or y = (-3/2)x

How can you quickly determine the number of roots a polynomial will have by looking at the equation?
One can determine the number of roots by seeing the degree of the given polynomial.
The number of roots can be determined by just seeing the highest power of the given equation.
1) for the equation x-4=0
here, the highest power of the equation is one. So, it will have one root.
What is the polynomial?A polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtract multiplication, on, and non-negative integer exponentiation of variables.
Let's check it by simplifying x-4=0 which implies x=4
Hence, the equation has only one root namely x = 4.
2) Consider a quadratic equation,
10t^2-t-3=0
here, the highest power of the equation is two. So, it will have two roots.
Let's check it by simplifying using the middle term splitting method,
10t^2+5t-6t-3=0
5t(2t+1)-3(2t+1)=0
(5t-3)(2t+1)=0
t=-3/5 or t=-1/2
Thus, the equation has two roots.
