1.)The slope is –2, and the y-intercept is 9.
2.)The slope is 2, and they y-intercept is 9.
3.)The slope is 9, and the y-intercept is –2.
4.)The slope is 9, and the y-intercept is 2.
Answers
Answer with explanation:
The equation of line in slope intercept form is :
y= m x +c
Where,m =Slope
c=Y intercept =Distance between origin and point where the line cuts the Y axis
The equation of line is
y= 9 x-2
Comparing with the above equation of line in slope intercept form
Slope =9
Y intercept =2
Option 4
The slope is 9, and the y-intercept is 2.

Which graph represents the system of inequalities?
y+2<5xy+3x>4y≥2x
Answers
Answer:
The correct option is 2.
Step-by-step explanation:
The given system of inequalities
[tex]y+2<5x[/tex]
[tex]y+3x>4[/tex]
[tex]y\geq 2x[/tex]
Inequality (1) can be written as
[tex]y<5x-2[/tex]
The related equation is
[tex]y=5x-2[/tex]
The slope of line is 5 and y-intercept is -2.
The sign of inequality is < , it means related line of inequality (1) is a dotted line and shaded region is below the line.
Inequality (2) can be written as
[tex]y>-3x+4[/tex]
The related equation is
[tex]y=-3x+4[/tex]
The slope of line is -3 and y-intercept is 4.
The sign of inequality is >, it means related line is a dotted line and shaded region is above the line.
Inequality (3) is
[tex]y\geq 2x[/tex]
The related equation is
[tex]y=2x[/tex]
The slope of line is 2 and y-intercept is 0.
The sign of inequality is ≥, it means related line is a solid line and shaded region is above the line.
In the below graph the common shaded region is the solution region.
Therefore the correct option is 2.

Find the value of ‘x' and the length of segment ab. if b is between a and c, and ab = 3x – 3 and bc = 4x + 8, and ac = 75, then find the value of ‘x' and ab. answer
Answers
To solve for 'x' and the length of segment AB, we use the equation AB + BC = AC, which simplifies to (3x - 3) + (4x + 8) = 75, revealing that 'x' = 10 and the length of AB is 27 units.
Explanation:The question requires us to find the value of 'x' and the length of segment AB given that B is between A and C, with AB = 3x – 3, BC = 4x + 8, and the total length AC = 75. To solve this, we set up an equation using the given lengths of segments AB and BC to equal the total length AC. This gives us the equation AB + BC = AC, which simplifies to (3x – 3) + (4x + 8) = 75.
First, we simplify the equation: 3x + 4x – 3 + 8 = 75, which reduces to 7x + 5 = 75. Subtracting 5 from both sides gives us 7x = 70. Dividing both sides by 7, we find that x = 10. With the value of x, we can find AB by substituting x back into its equation: AB = 3(10) – 3 = 30 – 3 = 27.
Therefore, the value of 'x' is 10 and the length of segment AB is 27 units.

The value of x is 9.7 inches, rounded to the nearest tenth.
Answer:
B. 9.7 in.
Step-by-step explanation:
We have been given an image of a triangle. We are asked to find the value of x.
We will use area of triangle formula to solve our given problem.
[tex]\text{Area of triangle}=\frac{1}{2}\times \text{Base*Height}[/tex]
[tex]47\text{ in}^2=\frac{1}{2}\times x*x[/tex]
[tex]2*47\text{ in}^2=\frac{1}{2}*2\times x^2[/tex]
[tex]94\text{ in}^2=x^2[/tex]
Taking square root of both sides we will get,
[tex]x=\sqrt{94\text{ in}^2}[/tex]
[tex]x=9.6953597\text{ in}\approx 9.7\text{ in}[/tex]
Therefore, the value of x is 9.7 inches and option B is the correct choice.
0.71428571428 as a fraction in simplest form
Answers
To express 0.71428571428 as a fraction, we use a geometric series and find that the simplest form is 713/999.
Explanation:To express 0.71428571428 as a fraction in simplest form, we first note that the fractional part of the decimal is 0.71428571428. Since the decimal has a repeating pattern, we can represent it as a fraction using a geometric series. Let x equal the fraction, then we have:
x = 0.71428571428
Multiplying both sides by 10 gives:
10x = 7.1428571428
Subtracting the original equation from the new equation eliminates the repeating part:
10x - x = 7.1428571428 - 0.71428571428
Simplifying, we get:
9x = 6.42857142852
Dividing both sides by 9, we find:
x = 0.71428571428 = 6.42857142852/9 = 713/999
Therefore, 0.71428571428 as a fraction in simplest form is 713/999.

What time is 8 hours and 51 minutes before 11:13 P.M.?
Answers
8 hours and 51 minutes before 11:13 P.M. is 2:22 P.M.
To find what time it is 8 hours and 51 minutes before 11:13 P.M., we need to subtract 8 hours and 51 minutes from 11:13 P.M. Here's a step-by-step explanation:
Start with the minute subtraction. Since 13 minutes is less than 51 minutes, we need to borrow one hour from the 11 P.M. So, we change 11:13 P.M. to 10:73 P.M.Now, subtract the minutes: 73 - 51 = 22 minutes. So now we have 10:22 P.M.Next, subtract the hours: 10 P.M. - 8 hours = 2 P.M.Thus, 8 hours and 51 minutes before 11:13 P.M. is 2:22 P.M.
How is multiplying radicals so similar to just simplifying them?
Answers
sqrt(45) can be written as the product of sqrt(9) and sqrt(5). Since the sqrt(9)= 3, the product becomes 3(sqrt(5)). When radicals are simpified, the perfect squares are factored out inside of the radical. sqrt(45) can be written as sqrt(9*5) since sqrt(9)=3, the result then becomes 3sqrt(5). They are similar because the same steps are taken with multiplying radicals as when radicals are simplified.
Which graph represents a function?
Answers
Answer:
1st and last one
Step-by-step explanation:
the first and the last one are the only ones that represent a function because for each value of x there is only one corresponding value of y.
A graph represents a function if each value of x corresponds uniquely to a value of y. These graphs, often called line graphs, can depict various types of functions like linear, quadratic, etc. The slope and position of the line will vary depending on the function's formula.
Explanation:
In the subject of Mathematics, specifically when dealing with functions and graphs, a graph represents a function if each value of x corresponds to a unique value of y. This means that different values of x will produce different values of y. Graphs can be produced using specific pairs of (x,y) data points.
These graphs may be named line graphs as they showcase the relationship between two variables: one measured on the horizontal axis (x) and the other on the vertical axis (y). An example could be a function where y = a + bx. If b > 0, the line of the graph slopes upward to the right. If b = 0, the line is horizontal. If b < 0, the line slopes downward to the right.
Graphs may also represent other types of functions like linear, quadratic, inverse, or exponential, depending on the equation of the relation between x and y. It's also important to note that there can be other types of graphs, such as a specific type of line graph shown, where the x-axis consists of data values and the y-axis consists of frequency points.

The design on Santana’s wall includes 16 pink stripes and 20 green stripes. Find the ratio of pink stripes to green stripes.
Answers
Divide both terms by 4
16/4 =4
20/4=5
The ratio of pink stripes to green stripes on Santana's wall is 4:5.
To find the ratio of pink stripes to green stripes on Santana's wall, we need to compare the two quantities. Santana has 16 pink stripes and 20 green stripes. The ratio can be simplified by finding the greatest common divisor of the two numbers and then dividing both by that number to find the simplest form.
In this case, the greatest common divisor of 16 and 20 is 4. We divide both numbers by 4 to simplify the ratio:
16 / 4 = 4
20 / 4 = 5
Therefore, the simplified ratio of pink stripes to green stripes is 4:5.
