James completely covered a square poster board using 68.2 inches with an exponent of 2.of cardstock. Which measurement is
closest to one side of the poster board in inches?
A) 34 in.
B) 8 in.
C) 6 in.
D) 30 in.
Answer:
A. 34in
Step-by-step explanation:
If James completely covered a square poster board using 68.2 inches with an exponent of 2, the the total perimeter of the square will be;
P = 2(68.2) = 136.4in
Since the perimeter of a square is expressed as:
P = 4L
136.4 = 4L
L = 136.4/4
L = 34.1in
Hence the measurement of one side of the square poster is closest to 34in

Find the slope of the line containing the pair of points.
(-9,- 8) and (-8,-6)
Answer:
slope = 2
Step-by-step explanation:
-8 - -6 / -9 - -8 = 2
Answer:
[tex]\frac{2}{1}[/tex] which is just 2
Step-by-step explanation:
slope = [tex]\frac{y2 - y1}{x2 - x1}[/tex]
So plug the numbers in, now it should look like [tex]\frac{-6 - (-8)}{-8 - (-9)}[/tex]
-6 - (-8) = 2
-8 - (-9) = 1
So the slope is [tex]\frac{2}{1}[/tex]

what is mean mode and median
Answer:
mean is the average of the numbers (add them all up then divided by how many number there are)
mode is the number that comes out the most often
range is the largest number minus the smallest
median is the middle number when they are lined up from greatest to the least (unless there's two)
Step-by-step explanation:
a song we learned in 5th grade XD that i still remember somehow
Answer:
This is what mean, median, and mode are-
Step-by-step explanation:
Mean is when you add all the number there are and divide by the total of numbers that you added together like this for example.
(1+2+3+4+5 = 15) THEN (15 / 5 = 3) THE MEAN IS 3.
Median is when you group the number from smallest to biggest and keep on crossing out both side of the number till you reach the middle.
(1, 2, 3, 4, 5) YOUR MEDIAN SHOULD BE 3 CAUSE IF YOU CROSS OUT 1,5 THEN 2,4 YOU WILL GET 3.
Mode are the most common number that you will see. You could have no mode or many mode too.
(1, 2, 2, 3, 4, 5) THERE IS ONLY ONE MODE HERE WHICH IS 2.
(1, 2, 3, 4, 5) THERE IS NO MODE CAUSE THERE IS NO REPEATING NUMBER.
(1, 2, 3, 4, 4, 5, 5) THERE IS TWO MODE NOW WHICH ARE 4 AND 5.

I think of a number, double it and subtract 1 and then square the answer. The result is 64. What could the number be?
If you doubled an unknown number and subtract 1 and then square the answer to get 64, the unknown number is 4.5.
Let the unknown number be n.Given the following data:
Output = 64To find an unknown number:
In this exercise, you're required to solve for an unknown number while performing some arithmetic operations such as multiplication, subtraction and square.
Translating the word problem into an algebraic expression, we have;
Doubling the unknown number, we would multiply by 2:
[tex]2n[/tex]
Subtracting 1 from the above and squaring, we have:

Simplify and solve for X.
5(x + 20) = 7x + 30
Answer:
X = 35
Step-by-step explanation:
5 + 100 = 7x + 30
5x + 100 - 100 = 7x + 30 - 100
5x = 7x - 70
5x - 7x = 7x - 70 - 7x
-2x = -70
-2x/-2 = -70/-2
x = 35

Find a solution for the equation. Assume that all angles are a cute angles. tan(3Y +32) = cot(Y+32°)
9514 1404 393
Answer:
Y = 6.5°
Step-by-step explanation:
We know that tan(x) = cot(90°-x), so we could rewrite the equation as ...
cot(90 -(3Y+32)) = cot(Y+32)
58 -3Y = Y +32
26 = 4Y
6.5 = Y
One solution is Y = 6.5°.

The perimeter of a triangular garden is 72 feet. Find the length of the three sides if the middle length side is 4 feet greater than twice the length of the smallest side, and the longest side is 4 feet less than 3 times the length of the smallest side
Answer:
Smallest length side = 12 ft
Middle length side = 28 ft
Longest length side = 32 ft
Step-by-step explanation:
Perimeter of ∆ = sum of all its length sides
Thus, we are given that:
Perimeter = 72 ft
Let x represent the smallest length side. Therefore:
Smallest length side = x ft
Middle length side = (2x + 4) ft
Longest length side = (3x - 4) ft
Thus:
(2x + 4) + (3x - 4) + x = 72
Solve for x
2x + 4 + 3x - 4 + x = 72
Collect like terms
2x + 3x + x + 4 - 4 = 72
6x = 72
Divide both sides by 6
x = 72/6
x = 12
Find the length of all 3 sides by plugging in the value of x in each expression:
Smallest length side = x ft = 12 ft
Middle length side = (2x + 4) ft = (2(12) + 4) = 24 + 4 = 28 ft
Longest length side = (3x - 4) ft = (3(12) - 4) = (36 - 4) = 32 ft

Part 1:
Graph the following system of equations. What is the solution set?
2x + y = 3
x = 2y - 1
Part 2:
Solve the following system of equations by substitution. What is the solution set?
y = -2x + 3
x - 2y = - 1
Part 3:
Compare the systems of equations and their solutions in Parts 1 and 2. How are they similar? How are they different?
Complete your work in the space provided or upload a file that can display math symbols if your work requires it. Include the graph of the linear system of equations and the process followed in order to solve the system by substitution.
Answer:
Part 1:
The solution set of the system of equations is x = 1, y = 1
Part 2:
The solution set is x = 1, y = 1
Part 3:
The similarity of the system of equations in Parts 1 and 2 is that they have the same solution set
The difference of the system of equations in Parts 1 and 2 is that they are arranged differently
Step-by-step explanation:
Part 1:
The system of equation is given as follows;
2·x + y = 3...(1)
x = 2·y - 1...(2)
The above system of equations can be written in terms of the variable, y, as follows;
For equation (1), we have;
y = 3 - 2·x
For equation (2), we have;
y = (x + 1)/2
From the attached graph created with Microsoft Excel, we have;
The solution set (the point of intersection) of the system of equations is x = 1, y = 1
To accurately find the common solution, we have;
(x + 1)/2 = 3 - 2·x
x + 1 = 2·(3 - 2·x) = 6 - 4·x
x + 1 = 6 - 4·x
x + 4·x = 6 - 1
5·x = 5
x = 5/5 = 1
x = 1
Therefore, y = 3 - 2·x = 3 - 2× 1 = 1, at the common solution
Part 2:
y = -2x + 3
x - 2y = -1
∴ x = 2y -1
y = -2(2y -1) + 3
y = -4y + 2 + 3
5y = 5
y = 1
x = 2y - 1 = 2 - 1 = 1
x = 1
The solution set is x = 1, y = 1
Part 3
The system of equations are similar in terms of their solution
The system of equations are different in terms of their arrangement

f(x)=x²+4x-7 determine the vertex
Answer:
The vertex of this parabola is [tex](-2,-11)[/tex]
Step-by-step explanation:
One way of finding the x-coordinate of the vertex of a parabola is by using the equation [tex]-\frac{b}{2a}[/tex]
From the function [tex]f(x)=x^2+4x-7[/tex], we can see that
[tex]a=1\\b=4\\c=-7[/tex]
This means that
[tex]-\frac{b}{2a}=-\frac{4}{2(1)} =-2[/tex]
So, the x-value of the vertex is -2. Now, we can plug this x-value into the function to find the y-coordinate of the point.
[tex]f(x)=x^2+4x-7\\\\f(-2)=(-2)^2+4(-2)-7\\\\f(-2)= 4-8-7\\\\f(-2)=-11[/tex]
Thus, the vertex of this parabola is [tex](-2,-11)[/tex]

the first number or part of a ratio is the numerator, and the second is the denominator, for part A 2 is the numerator and 3 is the denominator. the 30 is also the denominator so it would go on the bottom and x would be the numerator since we didn´t know the value of it. this also applies for Part B.
