Answer:

7 is the positive whole number which we can multiply by 3 and add 1, or multiply by 2 and add 8; and it will give the same answer.

Step-by-step explanation:

Multiplying the positive whole number 7 by 3 and adding 1 will get:

(7 × 3) + 1 = 21 + 1 = 22

Multiplying the positive whole number 7 by 2 and adding 8 will get:

(7 × 2) + 8 = 14 + 8 = 22

Therefore, 7 is the positive whole number which we can multiply by 3 and add 1, or multiply by 2 and add 8; and it will give the same answer.

Answer:

4 yd².

Step-by-step explanation:

From the question given above, the following data were obtained:

Length (L) = 2⅔ yards

Width (W) = 1½ yards

Area (A) =.?

The area of the piece of fabric that Roberto needs can be obtained by using the formula for calculating the area of a rectangle. This is illustrated below:

Area (A) = Length (L) × Width (W)

A = 2⅔ × 1½

A = 8/3 × 3/2

A = 8 × ½

A = 4 yd²

Thus, the area of the piece of fabric that Roberto needs is 4 yd²

Answer: g(x) = (1/3)*(-x)^2 + 3.

Step-by-step explanation:

Let's define all the transformations in a general way,

A vertical contraction/dilation of a scale factor a is written as:

g(x) = a*f(x)

where if a > 1, it is a dilation.

if  0 < a < 1, it is a contraction.

A reflection in the y-axis changes the value of the x-component and leaves the y-component invariable, then this transformation is written as:

g(x) = f(-x).

A translation of A units up (A positive) is written as:

g(x) = f(x) + A.

Then for this case we have:

A dilation with scale factor 1/3.

g(x) = (1/3)*f(x)

A reflection over the y-axis.

g(x) = (1/3)*f(-x)

A translation of 3 units up.

g(x) = (1/3)*f(-x) + 3

(in that order, remember that the order in which you applly the transformations matters)

Then g(x) = (1/3)*f(-x) + 3

and f(x) = x^2, so we can replace that in the equation for g(x)

g(x) = (1/3)*(-x)^2 + 3.

Transformation involves changing the position of a function.

The rule for g is: [tex]\mathbf{g(x) = \frac 13(x - 3)^2}[/tex]

The parent function is given as:

[tex]\mathbf{f(x) = x^2}[/tex]

The rule of vertical shrink by a factor of 1/3 is:

[tex]\mathbf{(x,y) \to (x,\frac 13y)}[/tex]

So, we have:

[tex]\mathbf{f'(x) = \frac 13x^2}[/tex]

The rule of reflection across the y-axis is:

[tex]\mathbf{(x,y) \to (-x,y)}[/tex]

So, we have:

[tex]\mathbf{f''(x) = \frac 13(-x)^2}[/tex]

[tex]\mathbf{f''(x) = \frac 13x^2}[/tex]

The rule of translation 3 units right is:

[tex]\mathbf{(x,y) \to (x - 3,y)}[/tex]

So, we have:

[tex]\mathbf{g(x) = \frac 13(x - 3)^2}[/tex]

Hence, the rule for g is: [tex]\mathbf{g(x) = \frac 13(x - 3)^2}[/tex]

Answer:

(1, -2)  Option A in your list of possible answers

See attached image.

Step-by-step explanation:

We need to graph the lines by using a couple of points on the plane for each equation.

For example:

the points (0, -3)  and (3, 0) for the line  y = x - 3

and the points (0, 1) and (-1, 4) for the line  y = - 3 x + 1

Please see the lines in the attached image, and notice that they intersect at the point (1, -2), which gives you the solution for the system.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

The value of the expression 4 + [tex](m - n)^4[/tex] at m = 7 and n = 5 is 20.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example:

2 + 3x + 4y = 7 is an expression.

3 + 4x = 5 is an expression.

We have,

An expression:

4 + [tex](m - n)^4[/tex]

We will solve the expression when m = 7 and n = 5.

Now,

4 + [tex](m - n)^4[/tex]

= 4 + [tex](7 - 5)^4[/tex]

= 4 + [tex]2^{4}[/tex]

[tex]2^{4}[/tex] = 2 x 2 x 2 x 2 = 16

= 4 + 16

= 20

Thus,

The value of the expression 4 + [tex](m - n)^4[/tex] at m = 7 and n = 5 is 20.

Well, the prime factorization would be 17 itself! This happens because 17 is a prime number.

If we take another example, like 13 or any other prime number, this will occur. Since 1 isn't a prime number, nor composite number, we won't include 1. Therefore, the prime factorization of 13 would also be 13 itself.

There are 25 students in each class.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

Let's assume that there are x students in each class.

Since there are two classes, the total number of students is 2x.

Now,

Since every student wrote 4 letters.

The total number of letters written = 4 x the number of students.

200 = 4 x (2x)

200 = 8x

x = 200/8

x = 25

Therefore,

There are 25 students in each class.

The missing values of the given quadratic function are option (b)-19,-15,-9,-1,9

Quadratic function is an function which contains one unknown variable and the highest power of this unknown variable is 2. Let x be the unknown variable then the quadratic function y in x is given by

y = ax²+bx+c, where a, b, c are constants and a≠0

Given that  a quadratic function y is:

y = x² +7x -9

Value of y  when x = -2

y(-2) =  (-2)² +7(-2) -9 = -19

Value of y  when x = -1

y(-1) =  (-1)² +7(-1) -9 = -15

Value of y  when x = 0

y(0) =  (0)² +7(0) -9 = -9

Value of y  when x = 1

y(1) =  (1)² +7(1) -9 = -1

Value of y  when x = 2

y(2) =  (2)² +7(2) -9 = 9

The missing values in the table are -19,-15,-9,-1,9
