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]

simply expression by adding/subtracting similar terms

=+8*y^3 +y^2  −11*y

to give the final answer.

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-by-step explanation:

Answer: 177 months

Step-by-step explanation:

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).

Answer:

If one number is x, the other is (96 - x)...since if you add those two together, you will get 96..and the product is x(96 - x) = 96x - x^2

Since this is a quadratic function (x to the power of 2), it is a parabola. More specifically, it is a parabola opening downwards, because there is a negative in front of the x squared. Because it downward facing the maximum value of x is going to be where the vertex is. The x value of the vertex can be found by taking the negative of b (which is the number in front of teh x) over a squared (which is the number in front of the x squared which in this case is 1)

So x = -96 / 2(-1) = -96/-2 = 48

Since as we first stated one number is x, the first number is 48

The second number will be 48, because we stated the second number to be 96-x

Therefore 48 times 48 will give you the maximum product 2304.

y = 120 - x

Product "P"

P = x × y = x(120-x) = 120x - x²

Suppose the square Lena draws has the following dimensions:

[tex]Side=L \\ \\ A_{s}:Area \\ \\ \\ A_{s}=L^2[/tex]

For the rectangle we have:

[tex]Base=L_{1} \\ \\ Height=L_{2} \\ \\ \\ A_{r}=L_{1}L_{2}[/tex]

Possibility 1. In order for the area of the square to be greater than the area of the rectangle, the following inequality must be true:

[tex]\boxed{\frac{L^2}{L_{1}L_{2}}>1}[/tex]

Possibility 2. If one side of the rectangle equals the side of the square, that is:

[tex]L_{1}=L[/tex]

Then, in order for the area of the square to be greater than the area of the rectangle, the following inequality must be true:

[tex]\frac{L^2}{LL_{2}}>1 \\ \\ \boxed{\frac{L}{L2}>1}[/tex]

The side lengths for Lena's square, with an area greater than rectangle B, must exceed the side lengths of rectangle B if square, or the square root of its area if not. Thus, any side length [tex]\( s \)[/tex] for Lena's square must satisfy [tex]\( s > \sqrt{A_B} \)[/tex], where [tex]\sqrt{A_B}[/tex] is area of rectangle.

Given that the area of the square is greater than the area of rectangle B, we can write the inequality:

[tex]\[ s^2 > l \times w \][/tex]

To find two possible side lengths for the square, we need to find values of [tex]\( s \)[/tex] that satisfy this inequality.

Since we do not have specific values for [tex]\( l \)[/tex] and [tex]\( w \)[/tex], we can consider a few scenarios:

1. If rectangle B is a square itself, then [tex]\( l = w \)[/tex], and the area of rectangle B would be [tex]\( l^2 \)[/tex]. For the square drawn by Lena to have a greater area, the side length [tex]\( s \)[/tex] must be greater than [tex]\( l \)[/tex]. So, any value of [tex]\( s \)[/tex] greater than [tex]\( l \)[/tex] would be a possible side length for Lena's square.

2. If rectangle B is not a square, then [tex]\( l \neq w \)[/tex]. Without loss of generality, let's assume [tex]\( l > w \)[/tex]. To ensure that [tex]\( s^2 > l \times w \)[/tex], [tex]\( s \)[/tex] must be greater than the square root of [tex]\( l \times w \)[/tex].

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.

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.

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.
