what is the explicit formula for this sequence? -7,-3,1,5
Answer:
[tex]a_{n}[/tex] = 4n - 11
Step-by-step explanation:
These are the terms of an arithmetic sequence with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
d = - 3 - (- 7) = 1 - (- 3) = 5 - 1 = 4
and a₁ = - 7, hence
[tex]a_{n}[/tex] = - 7 + 4(n - 1) = - 7 + 4n - 4 = 4n - 11
The explicit formula for the arithmetic sequence -7,-3,1,5 is an = -7 + (n-1)(4), where n is the position of the term in the sequence.
The student is asking for the explicit formula of the sequence -7,-3,1,5. This is an arithmetic sequence, where each term increases by a constant difference. The common difference (d) can be found by subtracting any term from the following term; for instance, -3 - (-7) = 4. To find the explicit formula, we'll denote the first term of the sequence as a1 which is -7. The explicit formula for an arithmetic sequence is an = a1 + (n-1)d. Substituting our values in, we get an = -7 + (n-1)(4).

Triangle ABC has vertices A(–2, 3), B(0, 3), and C(–1, –1). Find the coordinates of the image after a reflection over the x-axis
Answer:
A'(-2, -3) B'(0, -3) C'(-1, 1)
Step-by-step explanation:
change the signs for the Y coordinates because you are reflecting over the X-Axis. so 3 becomes -3, and -1 becomes 1. leave the X coordinates unchanged.
The reflection triangle ABC over the x axis is A'(–2, -3), B'(0, -3), and C'(–1, 1).
TransformationTransformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, rotation and dilation
If a point A(x, y) is reflected over the x axis, the new point is at A'(x, -y).
The reflection of A(–2, 3), B(0, 3), and C(–1, –1) over the x axis is A'(–2, -3), B'(0, -3), and C'(–1, 1).

Which equation represents a linear function?
y – 2 = –5(x – 2)
x + 7 = –4(x + 8)
y – 3 = y(x + 4)
y + 9 = x(x – 1)
Answer:
The first one: y - 2 = -5(x - 2)
Step-by-step explanation:
Answer:
the function y – 2 = –5(x – 2) is linear.
Step-by-step explanation:
We need to find the correct option from provided options which represents a linear function
Since, the linear equation is in the form of y=mx+c where m is slope of line.
In first part y – 2 = –5(x – 2)
Simplify, the function
[tex]y -2 = -5x + 10[/tex]
Add both the sides by 2, in above equation
[tex]y = -5x +12[/tex]
This function is in the form of y=mx+c
so, this is a linear function
In second part x + 7 = –4(x + 8)
Simplify, the function
[tex]x+7= -4x+32[/tex]
subtract both the sides by 7, in above expression
[tex]x= -4x+32-7[/tex]
[tex]x= -4x+25[/tex]
add both the sides by 4x,
[tex]x +4x= 25[/tex]
[tex]5x= 25[/tex]
divide both the sides by 5,
[tex]x =5[/tex]
This is not in the form of y=mx+c
so, this is not a linear function
In third part y – 3 = y(x + 4)
Simplify, the function
[tex]y-3= yx+4y[/tex]
add both the sides by 3,
[tex]y= yx+4y+3[/tex]
This is not in the form of y=mx+c
so, this is not a linear function
In fourth part y + 9 = x(x - 1)
Simplify, the function
[tex]y+9= x^{2}-x[/tex]
subtract both the sides by 9,
[tex]y= x^{2}-x-9[/tex]
This is not in the form of y=mx+c
so, this is not a linear function
Therefore, the function y – 2 = –5(x – 2) is linear.

Which of the following functions is graphed below?
The function that is graphed below is y = |x - 8| + 2.
Option A is the correct answer.
What is a function?A function has an input and an output.
A function can be one-to-one or onto-one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
The graph of the function y = |x - 8| + 2 is a V-shaped graph with the vertex at the point (8, 2).
The function is defined as the absolute value of the difference between x and 8, plus 2.
When x is less than 8, the expression inside the absolute value bars, (x - 8), is negative, so the function becomes y = -(x - 8) + 2.
Simplifying this expression, we get y = -x + 10, which is the equation of a line with a slope of -1 and a y-intercept of 10.
This line goes downwards to the left of the vertex (8, 2).
When x is greater than 8, the expression inside the absolute value bars, (x - 8), is positive, so the function becomes y = (x - 8) + 2.
Simplifying this expression, we get y = x - 6, which is the equation of a line with a slope of 1 and a y-intercept of -6.
This line goes upwards to the right of the vertex (8, 2).
At the vertex (8, 2), the function takes the minimum value of 2.
Overall, the graph of the function y = |x - 8| + 2 is a V-shaped graph with the vertex at (8, 2), and two lines with slopes of -1 and 1 on either side of the vertex. The graph is symmetrical about the vertical line x = 8.
Thus,
The function that is graphed below is y = |x - 8| + 2.

Use pythagorean theorem (a^2 + b^2 = c^2)
a = base
b = side
c = hypontenuse
then just plug the numbers into the formula -----> 6.3^2 + b^2 = 15.4^2
then subtract 6.3^2 from both sides ----> b^2 = 15.4^2 - 6.3^2
solve ------> b^2 = 197.47
Square root both sides and you get b = 14.1 mi as your answer

The axis of symmetry of function f is x =
. The axis of symmetry of function g is x =
Answer:
x = 10
Step-by-step explanation:
Please, use " ^ " to denote exponentiation: g(x) = 4(x - 2)^2 - 4
The vertex is located at (2, -4) which numbers come directly from the '2' in (x - 2) and the "-4" at the end of the equation.
Where is the function f(x) that you mentioned?
The axis of symmetry here is the vertical line that passes through the vertex. Its equation is x = 10.
The axis of symmetry for the function g(x) is x = 2, determined by the standard form of a quadratic equation, which tells us the axis of symmetry is at x = h, where g(x) is in the form a(x - h)^2 + k.
The question asks for the axis of symmetry for function g(x) which is given as g(x) = 4(x - 2)2 - 4. The axis of symmetry for a parabolic function in the form f(x) = a(x - h)2 + k is given by x = h. Thus, in the function g(x), the axis of symmetry is x = 2. If f(x) was provided in a similar quadratic form, its axis of symmetry would similarly be derived from its formula. However, since f(x) was not given in the question, we can't determine its axis of symmetry.

Samuel is in charge of ordering lunch..
Answer:
The correct answer is D.
The correct identity Samuel should use is: D. (20 x 6) + (4 x 6) = 24 x 6
To find the total cost of ordering 24 lunch specials at $6.00 each, Samuel needs to compute 24×6.
The distributive property states that:
a×(b+c) = (a×b)+(a×c)
In this problem, we can break down 24 into 20 and 4, and then apply the distributive property.
This gives us:
24×6 = (20+4)×6
= (20×6) + (4×6)
The border line of the linear inequality 4x+7y<5 is dotted. True or false
Answer:
True
Step-by-step explanation:
The region defined by the following inequality
[tex]4x+7y<5[/tex]
is delimited by the line: [tex]4x+7y=5[/tex]
Therefore the points that are on the line that delimits the region are those where [tex]4x+7y=5[/tex]
Since the symbol "<" represents only the values that are smaller and excludes those that are greater or equal, then the points where [tex]4x+7y=5[/tex] are not included in the region. This is represented by drawing a dotted line
The statement is true; the border line of the inequality 4x+7y<5 is drawn as a dotted line because it does not include the boundary points as part of the solution set.
The statement that the border line of the linear inequality 4x+7y<5 is dotted is true. When graphing a linear inequality, the border line is typically solid if the inequality includes the equality (≤ or ≥), which indicates that the points on the line are included in the solution set. However, when the inequality does not include equality ( < or > without the line underneath), as in 4x+7y<5, the border line is drawn as a dotted line, signifying that points on the line are not part of the solution set. Therefore, the given statement is correct and the border line should indeed be dotted.
A brownie recipe asks for two and one third times as much sugar as chocolate chips. If three and one half cups of sugar is used, what quantity of chocolate chips would then be needed, according to the recipe?
Answer:
1 1/2 cups.
Step-by-step explanation:
If the quantity of chocolate chips is x cups then:
x * 2 1/3 = 3 1/2
x * 7/3 = 7/2
x = 7/2 / 7/3
x = 7/2 * 3/7
x = 3/2 = 1 1/2 cups.
The quantity of chocolate chips needed for the brownie recipe when using three and one half cups of sugar, divide the amount of sugar by the sugar-to-chocolate chips ratio of 2 1/3. The answer is one and one half cups of chocolate chips.
Related to ratios and proportions in a brownie recipe. If a recipe calls for two and one third times as much sugar as chocolate chips, and if three and one half cups of sugar is used, you can calculate the amount of chocolate chips required as follows:
First, it's important to understand the ratio given: 2 1/3 cups of sugar for every 1 cup of chocolate chips.
Next, since we know that 3 1/2 cups of sugar are used, you need to divide the amount of sugar by the ratio to find the amount of chocolate chips needed, which is, 3 1/2 divided by 2 1/3.
To perform the division, you first convert the mixed numbers into improper fractions. 3 1/2 becomes 7/2, and 2 1/3 becomes 7/3.
Now, divide 7/2 (the amount of sugar) by 7/3 (the sugar-to-chips ratio) to get the amount of chocolate chips required.
This is the same as multiplying 7/2 by the reciprocal of 7/3, which is 3/7. The sevens cancel out, and the result is 3/2, or one and one half (1 1/2) cups of chocolate chips required for the recipe.

Factor this polynomial completely x^2-64
Answer:
(x + 8)(x - 8)
Step-by-step explanation:
Difference of squares
a^2 - b^2 = (a + b)(a - b)
In this case
x^2 - 64
= x^2 - 8^2
= (x + 8)(x - 8)
The equation x² - 64 is a difference of two squares and can be factored using the formula for the difference of squares, which leads to (x - 8)(x + 8).
Explanation:The equation given is x² - 64, which is a difference of two squares. In mathematics, the difference of two squares is any expression that can be rewritten as the square of a number or expression, subtracted from the square of another number or expression. To factor this expression, we can use the formula a² - b² = (a - b)(a + b).
So, we have
x² - 64
= (x)² - (8)². Applying the formula, this factors to (x - 8)(x + 8).

The perimeter of the scalene triangle is 60 cm. The length
of the longest side is 4 times that of the shortest side.
Which statements about the possible measures of the
sides are reasonable? Check all that apply.
The value of x can equal 40.
The longest side can equal 30 cm.
The shortest side can equal 7 cm.
The value of x can equal 25.
The shortest side can equal 5.
Answer:
Step-by-step explanation:
Perimeter = 60 cm
longest side = 4* shortest side (x)
longest side = 4x
shortest side = x
third (intermediate side=y= 60 -x -4x = 60-5x
The triangle inequality specifies that the sum of the two shorter sides must be greater than the longest side to form a triangle. Hence
x + y > 4x
x + 60-5x > 4x
60 - 4x > 4x
8x < 60
x < 60/8 = 7.5, or
x < 7.5
Therefore to form a triangle, x must be less than 7.5 cm.
Now if we look at the options both 7 and 5 are less than 7.5 cm.
40, 30 and 25 all have a problem because the longest side (4 times longer) will exceed the perimeter of 60.
Now also examine cases where 4x is not the longest side, in which case we need
4x>=y
or
4x >= 60-5x
9x >=60
x >= 6.67
so x=5 will not qualify, because 4x will no longer be the longest side.
The only valid option is x=7 cm
The side lengths for x=7 and x=5 are, respectively,
(7, 25, 28)....
