Answer:
The slops is -4
Step-by-step explanation:
Given
x: -1 1 3 5
y: 10 2 -6 -14
Required
The slope
Pick any pair of x and y
[tex](x_1,y_1) = (-1,10)[/tex]
[tex](x_2,y_2) = (1,2)[/tex]
The slope is:
[tex]m = \frac{y_2 - y_1}{x_2 -x_1}[/tex]
[tex]m = \frac{2 -10}{1 --1}[/tex]
[tex]m = \frac{-8}{2}[/tex]
[tex]m = -4[/tex]

Khan Academy
It's Friday afternoon and six fraternity brothers at UNC have just attended their last class of the semester. To unwind before the final exam Monday morning, they decide to spend the weekend at the beach. After a weekend of immature, irresponsible behavior, they oversleep Monday morning and miss the final exam. Later that day they go to their professor (who received her Ph.D. from NC State) and explain that they went to the beach and were on the way back for the final exam but their car (a BMW of course) had a flat tire. The professor says that they can come back the next morning and she will give them a make-up final exam consisting of one short-answer question! The students are ecstatic and high-five each other all the way back to the frat house. The next morning the professor puts each student in a different room and hands them their one-question test. The question: Which tire?
Required:
What is the probability that all 6 students will say that the same tire was flat?

What does it mean to multiply polynomials?
Explain how to multiply (x + 2) (X - 4) as if you're teaching a student a year
younger than you.
Answer:
We assume before this you have learned how to multiply two monomials and monomial with binomial.Use the following formula to multiply binomials:
(a + b)(c + d) = ab + ad + bc + bdApplied to the given expression, we have:
(x + 2)(x - 4), where a = x, b = 2, c = x , d = -4Expand as indicated above:
(x + 2)(x - 4) =x(x) + x(-4) + 2(x) + 2(-4)Now simplify
x² - 4x + 2x - 8Collect like terms, (-4x) and (2x):
x² + (-4x + 2x) - 8 = x² - 2x - 8This is how you can do same order operations with any binomials.
We can simply use distributive law of grade 1
(a+b)(c+d)=ac+ad+bc+bdI assume you know multiplication of monomials
So
(x+2)(x-4)x(x-4)+2(x-4)x²-4x+2x-8x²-2x-817 apples for $3.91 what is the unit rate per apple
9514 1404 393
Answer:
$0.23 per apple
Step-by-step explanation:
The cost per apple is found by dividing the cost by the number of apples. (You can think of "per" as meaning "divided by".)
cost/apple = $3.91/(17 apples) = $0.23 /apple

What does a single point on the plot represent?
make sure to show how you got your answer
Answer: 0.075
Step-by-step explanation: when you are working with percentages to decimals you want to move the decimal two places to the left. If you are working with decimals and you want to make it a percentage you would move the decimal two places to the right.
Answer:
7.5% = 0.075
Step-by-step explanation:
Whenever you're converting a percentage into a decimal, you multiply the percentage by 100, or move the decimal point two points to the left. So, 7.5% as a decimal is 0.075.

PLEASE HELP (5th grade math) giving away Brainliest
Answer:
y = [tex]\frac{3}{1}[/tex]+1First, we should know what the slope-intercept formula is.
Y = MX + B
Where M is your slope, and B is your y intercept.
Let's do the easiest part first, finding our y-intercept. The y-intercept is where the the line intersects the y-axis. In this case, y = 1, because it intersects at (0, 1).
Now we have:
y = mx + 1
Next, we need to calculate the slope, or rise over run. M is presented as a fraction. The numerator is your rise (how high or low it goes), and the denomenator is your run (how far to the right or left it goes).
If it goes LEFT, the number is negative, if it goes RIGHT it is positive.
Also, pretty points are areas in which the line hits an exact coordinate. Using these points is easiest if you want to find the slope of the line.
We can see that the line hits a pretty point every time it goes one coordinate (box) to the right, and up three boxes. What this means it is rises three 3 points, and runs to the right, 1. This is shown as [tex]\frac{3}{1}[/tex]
So let's add that to the equation!
y = [tex]\frac{3}{1}[/tex]+1
a farmer wants to fence in three sides of a rectangular field shown below with 960 feet of fencing. The other side of the rectangle will be a river. If the enclosed area is to be a maximum, find the dimensions of the field.
9514 1404 393
Answer:
240 ft by 480 ft
Step-by-step explanation:
Area is maximized when the long side is half the total length of the fence. That makes the short side (out from the river) be half the length of the long side.
The fenced field dimensions are 240 feet by 480 feet.
__
You can let x represent the length of the long side. Then the length of the short side is half the remaining fence: (960 -x)/2.
The total area is the product of these dimensions:
A = x(960 -x)/2
We note that this is the equation of a parabola with zeros at x=0 and x=960. The maximum will be found on the line of symmetry, halfway between the zeros. That is at x = (0 +960)/2 = 480.
The area is maximized for a long-side dimension of 480 feet. The short sides are 240 feet.
circle WX = xy 2x+16, xw 7x-29 find wx
The value of WX will be; (8y³)/(7y+8).
To find the length of WX, we need to substitute the given values of x and simplify the expression:
WX = xy/(2x+16) - xw/(7x-29)
xy/(2x+16) = xw/(7x-29)
Cross-multiplying, we get:
xy(7x-29) = xw(2x+16)
Expanding both sides;
7x²y - 29xy = 2x²w + 16xw
Rearranging terms and factoring out x;
x(7xy - 2xw) = 29xy - 16xw
Solving for x, we get:
x = (29xy - 16xw)/(7xy - 2xw)
Now we can substitute this value of x into the expression for WX to find its value. use the expression WX = xy/(2x+16):
WX = xy/(2x+16)
WX = y(29xy - 16xw)/[2(7xy - 2xw) + 16]
Simplifying the denominator,
WX = y(29xy - 16xw)/[14xy - 4xw + 16]
Finally, we can substitute the given values of xw and xy to get,
WX = y(29xy - 16xw)/[14xy - 4xw + 16] = (8y³)/(7y+8)
Therefore, WX = (8y³)/(7y+8).

A B C OR D SOMEONE HELP
Answer:
B
Step-by-step explanation:
Perpendicular lines have slopes that are negative reciprocals. For example. if the slope of a line is 2, the slope of a line perpendicular to it would be [tex]-\frac{1}{2}[/tex]. If the slope of a line [tex]-\frac{1}{3}[/tex], the slope of a line perpendicular to it would be 3.
Negative reciprocals always have a product of -1, since the numerators cancel out and one of the values is negative.

square root function is the correct answer
The solution is, y = 2 ^ (x + 2) +3, is the function is shown in the graph below.
What is graph?In mathematics, the graph of a function f is the set of ordered pairs, where {\displaystyle f(x)=y.} In the common case where x and f(x) are real numbers, these pairs are Cartesian coordinates of points in two-dimensional space and thus form a subset of this plane.
here, we have,
For this case we observe the cut point with the y axis in:
(0, 7)
The function that complies with this is:
y = 2 ^ (x + 2) +3
We have then:
y = 2 ^ (0 + 2) +3
y = 2 ^ (2) +3
y = 4 + 3
y = 7
Answer:
The answer for this case is given by:
y = 2 ^ (x + 2) +3
option 2
Hence, The solution is, y = 2 ^ (x + 2) +3, is the function is shown in the graph below.

Given:
Area of trapezoid = 16.3 km²
Length of parallel side 1 = 5.9 km
Height of trapezoid = 3.7 km
Find:
Length of parallel side 2
Computation:
Area of trapezoid = [Sum of parallel side/2]Height
Area of trapezoid = [(a+b)/2]h
[(5.9 + b)/2]3.7 = 16.3
Length of parallel side 2 = 2.91 km
