what is the slope of the line that contains points (-3, 1) and (4, -2)?
The slope of the line is [tex]m=-\frac{3}{7}[/tex]
Explanation:
The points are [tex](-3,1)[/tex] and [tex](4,-2)[/tex]
We need to find the slope of the line that contains the points [tex](-3,1)[/tex] and [tex](4,-2)[/tex]
The slope of the equation can be determined using the formula,
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Substituting the points [tex](-3,1)[/tex] and [tex](4,-2)[/tex] in the slope formula, we have,
[tex]m=\frac{-2-1}{4-(-3)}[/tex]
Simplifying the expression, we have,
[tex]m=\frac{-2-1}{4+3}[/tex]
Adding the terms in both numerator and denominator, we have,
[tex]m=\frac{-3}{7}[/tex]
The slope of the line that contains the points [tex](-3,1)[/tex] and [tex](4,-2)[/tex] is [tex]m=-\frac{3}{7}[/tex]
Thus, the slope of the line is [tex]m=-\frac{3}{7}[/tex]

In the diagram above, if the circle with the center A has an area of 72 pi, what is the area of the circle with center B?
18pi
24pi
30pi
36pi
48pi
Without additional information about the relationship between the two circles, it is not possible to definitively determine the area of circle B based on the area of circle A. If the circles are identical, the area of circle B is also 72 pi.
Explanation:Given the area of the circle with the centre A is 72 pi, we find the radius using the formula for the area of a circle: A = πr². Therefore, the radius of circle A, rA, can be found by rearranging the formula to rA = √(A/π). This gives us a radius of √(72) = 8.48 units. Without further information about the relationship between circle A and circle B, we cannot definitively determine the area of circle B. If the two circles are identical, then the area of circle B would also be 72 pi. However, if the radius or diameter of circle B is different, you would have to use that measurement to calculate the area using the formula A = πr².

What is the distance between the two points located at (14, 27) and (14, −8)?
The distance between the 2 given points is 35 units
Step-by-step explanation:
Step 1 :
Let A be the point (14, 27) and B be the point (14, −8).
Distance between any 2 points is obtained by the taking root of the sum of squares of the difference between the x co ordinates and the y co ordinates and is given by the formula
[tex]\sqrt({x_{2} - x_{1}) ^{2} + ({y_{2} - y_{1}) ^{2} }[/tex]
Where [tex](x_{1} , y_{1}) and (x_{2} , y_{2})[/tex] are the 2 points
Step 2 :
Using the above formula , we get the distance between the 2 given points as
[tex]\sqrt({14-14)^{2} + {((-8)-27)^{2} }[/tex] = [tex]\sqrt{(-35)^{2} }[/tex] = 35 units
Step 3 :
Answer:
The required distance of the 2 given points is 35 units
What is the length and width of a rectangle given by the trinomial r squared - 6r- 55? Use factoring
Answer:
The length and width are
r-11 and r+5
Step-by-step explanation:
The given trinomial is
[tex] {r}^{2} - 6r - 55[/tex]
To factor, we need to split the middle term to get:
[tex]{r}^{2} - 11r + 5r - 55[/tex]
We now factor by grouping to obtain;
[tex]{r}(r- 11) + 5(r - 11)[/tex]
We collect common factors again to get:
[tex](r- 11)(r + 5)[/tex]
Therefore the length and width are
r-11 and r+5

To solve the equation X + U = V, subtract the matrix U from both sides and simplify to find the solution for X. The solution is [12 - 4 - 14; -8 - 13 8; 8 15 18].
Explanation:To solve the equation X + U = V, we need to isolate X. Here is the step-by-step process:
First, subtract the matrix U from both sides of the equation: X = V - U.Next, subtract the corresponding elements of U from V. In this case, subtract the elements of U from the corresponding elements of V: X = [13 - 1 - 71; -6 1 19; 0 15 23] - [1 3 -57; 2 14 11; -8 0 5].Perform the subtraction and simplify: X = [12 - 4 - 14; -8 - 13 8; 8 15 18].The solution for X is the matrix [12 - 4 - 14; -8 - 13 8; 8 15 18].

what does have no change mean in math
Answer:
things are the same as they were
Step-by-step explanation:
"No change" in math means the same thing it does in English. Whatever it is you're looking at is the same now as it was before. It has not changed. The amount of change is zero.
Final answer:
In mathematics, 'no change' refers to a situation where a value or quantity remains constant over time or during certain operations. It can be used in various contexts, including functions, equations, and graphing to represent a static state.
Explanation:
In mathematics, the term 'no change' often refers to a situation where a value remains constant over time or through a particular process. For example, if a quantity does not increase or decrease, we can say that there has been no change in that quantity. Another way this might come up is in functions or equations, where certain operations have no effect on the input value, meaning the output remains the same as the input.
No change could also mean that a variable or a set of variables remains unaffected by certain transformations. In algebra, it might refer to a constant function where, regardless of the input, the output is always the same. No change might also be used in the context of graphing; if a graph stays flat without any increase or decrease, it represents no change in the value being graphed over the specified domain.

Are the expressions (5+5+5+5) + (x+x+x+x) and 4(5+x) equivalent? If so, write another expression that is equivalent to both of them. If not, explain why not.
Answer:
Yes, they are equivalent. Something that is not equivalent is 5(9+10x)
Both expressions simplify to 20 + 4x. Distributing 4 in 4(5+x) yields the same result, confirming their equivalence.
Sure, let's break it down step by step:
1. **Start with the first expression**: (5+5+5+5) + (x+x+x+x)
- First, simplify the terms inside each set of parentheses:
= (20) + (4x)
- Then, add the simplified terms together:
= 20 + 4x
2. **Proceed to the second expression**: 4(5+x)
- Apply the distributive property, which states that multiplying a number by a sum is the same as multiplying the number by each term in the sum and then adding the results:
= 4 × 5 + 4 × x
- Multiply each term inside the parentheses by 4:
= 20 + 4x
3. **Compare the results**:
Both expressions simplify to 20 + 4x.
In both cases, we ended up with the same simplified expression, 20 + 4x. This confirms that the original expressions are equivalent.
To write another equivalent expression, we can distribute the 4 to both terms inside the parentheses in the expression 4(5+x), which results in 20 + 4x. Therefore, the expression 20 + 4x is equivalent to both (5+5+5+5) + (x+x+x+x) and 4(5+x).
Subtract.
Your answer should be a polynomial in standard form.

In the diagram ABCD is a rectangle and PQ is parralell to AD
For the given rectangles, [tex]f=4[/tex] cm and [tex]g = 6[/tex] cm.
Step-by-step explanation:
Step 1:
The area of a rectangle is calculated by multiplying its length with its width. Both the rectangles APQD and PBCQ have the same width.
The second rectangle PBCQ has a length of 9 cm. Its area is determined by subtracting the area of APQD from the area of ABCD.
The area of the rectangle PQBC [tex]= 60 - 24 = 36[/tex] [tex]cm^{2}[/tex].
Step 2:
The length of rectangle PBCQ is 9 cm and the area is 36 [tex]cm^{2}[/tex] so the width can be determined.
[tex]Width = \frac{area}{length} = \frac{36}{9} = 4[/tex] cm. So [tex]f=4[/tex] cm.
Step 3:
The width of the rectangle APQD is also 4cm.
The width of the rectangle APQD is 4 cm and the area is 24 [tex]cm^{2}[/tex].
[tex]length = \frac{area}{width} = \frac{24}{4} = 6[/tex] cm. So [tex]g = 6[/tex] cm.

Among the three sides of length 9cm,11cm and 13cm;
9cm is the shortest and 13cm is the longest
the shortest of the corresponding i.e 9cm real - life distance= 125 km
Therefore, the longest of the corresponding i.e 13cm real - life distance= 125 ×13/9
= 180.55
= 180.6 km
A cylinder-shaped container is used to store water. The container has a height of 6 feet and a diameter of 3 feet. About how much water is in the container when it is 3/4 full?
A. 127 cubic feet
B. 42 cubic feet
C. 32 cubic feet
D. 14 cubic feet
Answer:
C. 32 cubic feet
Step-by-step explanation:
The volume of a cylinder can be written in terms of diameter as ...
V = (π/4)d^2·h
If water fills the 6-foot height to only 4.5 feet, then the volume of water is ...
V = (π/4)(3 ft)^2(4.5 ft) ≈ 31.81 ft^3
The volume of water in the container is about 32 cubic feet.

Step-by-step explanation:
Your math test has 38 questions and is worth 200 points. The test consists of
multiple-choice questions worth 4 points each and open-ended questions
worth 20 points each. How many of each type of question are there?
The test has 35 multiple-choice questions and 3 open-ended questions.
To solve this, we can set up a system of linear equations. Let x represent the number of multiple-choice questions and y represent the number of open-ended questions.
Equation 1: x + y = 38 (total questions)
Equation 2: 4x + 20y = 200 (total points)
By solving this system of equations, we can find the values of x and y. First, multiply equation 1 by 4 and subtract it from equation 2:
4(x + y) = 4(38) => 4x + 4y = 152
4x + 20y = 200 - (4x + 4y = 152) gives: 16y = 48 or y = 3.
Substituting y = 3 into equation 1 gives: x = 38 - 3 = 35.
Therefore, there are 35 multiple-choice questions and 3 open-ended questions on the test.
