The slope of the line below is 2. Which of the following is the point-slope form of the line?
Answers
The correct point-slope form of the line is A. y + 1 = 2(x - 1).
The point-slope form of a linear equation is given by y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope of the line.
Given that the slope of the line is 2 and the point on the line is (1, -1), we can substitute these values into the point-slope form to find the correct equation.
Using the point-slope form, we have:
y - (-1) = 2(x - 1)
Simplifying the equation, we get:
y + 1 = 2(x - 1)
Now we compare this equation to the answer choices:
A. y + 1 = 2(x - 1)
B. y - 1 = -2(x + 1)
C. y + 1 = -2(x - 1)
D. y - 1 = 2(x + 1)
Comparing the equation y + 1 = 2(x - 1) to the given point-slope form, we see that they match.
In this equation, the point (1, -1) lies on the line, and the slope of the line is 2. The equation represents a line with a slope of 2 that passes through the point (1, -1).

While organizing her DVD collection, Jessica put 5 DVDs on the first rack, 10 DVDs on the second rack, 20 DVDs on the third rack, 40 DVDs on the fourth rack, and 80 DVDs on the fifth rack. If this pattern continues, how many DVDs will Jessica put on the sixth rack?
Answers
Answer:
160
Step-by-step explanation:
Number of DVDs put on the first rack = 5
Number of DVDs put on the second rack = 10
If we closely observe, the number of DVDs on the second rack is nothing but number of DVDs on the first rack multiplied by 2.
Number of DVDs put on the third rack = 20
If we closely observe, the number of DVDs on the third rack is nothing but number of DVDs on the second rack multiplied by 2.
Number of DVDs put on the fourth rack = 40
If we closely observe, the number of DVDs on the fourth rack is nothing but number of DVDs on the third rack multiplied by 2.
Number of DVDs put on the fifth rack = 80
If we closely observe, the number of DVDs on the fifth rack is nothing but number of DVDs on the fourth rack multiplied by 2.
Therefore, to find the number of DVDs on the sixth rack as per similar pattern, we need to multiply the number of DVDs on the fifth rack with 2.
Number of DVDs on the sixth rack = [tex]80\times 2 = \bold{160}[/tex]

If gym strong charges a $350 fee and $15 a month and gym fit charges $100 fee and $24 a month, how many months would take for gym string to be a better buy?
Answers
Answer:
It would take 28 months for Gym Strong to be a better buy.
Step-by-step explanation:
There are two possible options for gyms to choose from:
Gym Strong charges $350 plus $15 a month
Gym Fit charges $100 plus $24 a month.
Since Gym Strong charges less per month but has a higher initial fee, there will be some time when it will be a cheaper option than Gym Fit.
Let's solve this by analyzing the differences in fixed fees and monthly fees.
The difference of fixed fees is $350 - $100 = $250
The difference on monthly fees is $24 - $15 = $9
Both gyms will charge the same total fees when have passed 250/9 = 27.7 months. Since the number of months is a whole number, we round up.
It would take 28 months for Gym Strong to be a better buy.

In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable , functions are indispensable for formulating physical relationships.
The domain is all real numbers for x>3 and the range of the square root function graphed is equal to the interval------> [1,∞)
so, the range is all real numbers for x>3

Hi. Please i need help with this . No jokes .
Answers
Answer:
I) The roots are:
First Case:
[tex]x=-2\text{ or } x=-6[/tex]
Second Case:
[tex]x=2\text{ or } x=6[/tex]
II) Possible values of p are:
First Case:
[tex]p=-12[/tex]
Second Case:
[tex]p=4[/tex]
Step-by-step explanation:
We have the equation:
[tex]x^2-(4+p)x+12=0[/tex]
We know that one of the roots is three times the other.
And we want to find the roots of the equation and the possible values for p.
To find our solutions, we can use the process of factoring.
If we have an equation in the form:
[tex]x^2+bx+c=0[/tex]
We want to find two numbers, say, k and j, such that:
[tex]\displaystytle kj=c\text{ and } k+j=b[/tex]
After finding them, we can factor as such:
[tex](x+k)(x+j)[/tex]
So, -k and -j will be our zeros.
Therefore, for our equation, we will find two numbers k and j such that:
[tex]\displaystyle kj=12\text{ and } k+j=-(4+p)[/tex]
Notice that for the first criterion, we can simply list all the factors of 12.
So, according to the first equation, possible values of k and j are:
1 and 12; 2 and 6; or 3 and 4.
Then, our roots will be -1 and -12; -2 and -6; or -3 and -4, respectively.
However, remember that one of our roots is three times the other.
Therefore, the only candidates that work will be the second option.
Hence, k and j are 2 and 6.
Therefore:
[tex]k=2\text{ and } j=6[/tex]
With this information, we can now determine p. Since:
[tex]k+j=-(4+p)[/tex]
Then it follows that:
[tex]\begin{aligned}(2)+(6)&=-(4+p)\\8&=-(4+p)\\-8&=4+p\\p&=-12\end{aligned}[/tex]
Hence, our equation is:
[tex]x^2-(4+-12)x+12=0[/tex]
Or, factored:
[tex]x^2+8x+12=0 \text{ or } (x+6)(x+2)=0[/tex]
So, our roots are x=-6 and x=-2 when p=-12.
However, we also need to consider the negative factors of 12.
Factors of 12 also include -2 and -6.
Hence, our k and j can also be k=-2 and j=-6.
Then, in this case, our p is :
[tex]\begin{aligned} (-2)+(-6)&=-(4+p)\\-8&=-(4+p)\\8&=4+p\\p&=4\end{aligned}[/tex]
Therefore, for our second case, k=-2 and j=-6. Then p=4. So, our equation is:
[tex]x^2-(4+4)x+12=0[/tex]
Or, factored:
[tex]x^2-8x+12\text{ or } (x-2)(x-6)=0[/tex]
Hence, when p=4, our roots are x=2 and x=6.
Fill in the table using this function rule.
