Answer:

The answer is [tex]\frac{4y}{y+3}[/tex] ⇒ the 4th answer

Step-by-step explanation:

* Lets talk about the product of two fraction

- If we have two fraction a/b and c/d, the product of them

  will be ac/bd

- The there is any simplify can do between numerator and

  denominator we must to make it

Ex: 2a²/5b × 15b/4a, we can simplify 2a² with 4a at first and

      simplify 15b with 5b and then put the answer

∵ 2a²/4a = a/2 ⇒ 2 ÷ 4 = 1/2 and a² ÷ a = a

∵ 15b/5b = 3 ⇒ 15 ÷ 5 = 3 and b ÷ b = 1

∴ 2a²/5b × 15b/4a = a/1 × 3/2 = 3a/2

* Now lets solve the problem

∵ [tex]\frac{2y}{y-3}*\frac{4y-12}{2y+6}[/tex]

- We can simplify the second fraction at first

∵ [tex]\frac{4y-12}{2y+6}=\frac{4(y-3)}{2(y+3}=\frac{2(y-3)}{y+3}[/tex]

- At first we took 4 as a common factor from 4y - 12 ⇒ 4(y - 3)

 and then simplify 4 with 2 in the denominator

- we can cancel the term x - 3 in the numerator of the second

 fraction with the same term in the denominator of the first fraction

∴ [tex]\frac{2y}{1}*\frac{2(1)}{y+3}=\frac{4y}{y+3}[/tex]

* The answer is [tex]\frac{4y}{y+3}[/tex]

Answer:

[tex]\large\boxed{y=-\dfrac{3}{2}x+11}[/tex]

Step-by-step explanation:

The slope-intercept form of an equation of a line:

[tex]y=mx+b[/tex]

m - slope

b - y-intercept

The formula of a slope:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have the point A(8, -1) and B(-4, 17). Substitute:

[tex]m=\dfrac{17-(-1)}{-4-8}=\dfrac{18}{-12}=-\dfrac{3}{2}[/tex]

The equation of a line:

[tex]y=-\dfrac{3}{2}x+b[/tex]

Put the coordinates of the point A(8, -1) to the equation of a line:

[tex]-1=-\dfrac{3}{2}(8)+b[/tex]

[tex]-1=-3(4)+b[/tex]

[tex]-1=-12+b[/tex]     add 12 to both sides

[tex]11=b\to b=11[/tex]

Finally we have the equation of a line in a slope-intercept form:

[tex]y=-\dfrac{3}{2}x+11[/tex]

The mathematical expression for "the product of z, x, and y" can be represented as [tex]\( z \times x \times y \)[/tex].

The mathematical expression for "the product of z, x, and y" can be represented as [tex]\( z \times x \times y \)[/tex]. In this expression, the symbol [tex]\( \times \)[/tex] denotes multiplication, and the three variables [tex]\( z \), \( x \), and \( y \)[/tex] are multiplied together to obtain their product.

This expression succinctly captures the idea of multiplying these three variables. In mathematical terms, a product refers to the result of multiplying two or more numbers or variables.

Therefore, [tex]\( z \times x \times y \)[/tex] represents the outcome of multiplying the values represented by the variables [tex]\( z \), \( x \), and \( y \)[/tex].

This expression provides a clear and concise way to articulate the mathematical concept of the product of three variables.

The product of ( z ), ( x ), and ( y ) is: ( zxy ).

To translate the phrase "the product of ( z ), ( x ), and ( y )" into a mathematical expression, follow these steps:

1. Identify the Variables:

  The variables involved in the expression are ( z ), ( x ), and ( y ).

2. Understand the Operation:

  The term "product" indicates multiplication.

3. Write the Expression:

  To express the product of ( z ), ( x ), and ( y ) mathematically, you simply multiply these variables together.

1. Start with the First Two Variables:

  Multiply ( z ) and ( x ) together.

[tex]\[ z \times x \][/tex]

2.Include the Third Variable:

  Now, multiply the result from the first step by ( y ).

[tex]\[ (z \times x) \times y \][/tex]

3. Simplify the Expression:

  In multiplication, the order in which you multiply numbers does not matter due to the commutative property of multiplication. Therefore, we can drop the parentheses.

[tex]\[ z \times x \times y \][/tex]

The mathematical expression for "the product of ( z ), ( x ), and ( y )" is:

[tex]\[z \cdot x \cdot y\][/tex]

or simply:

[tex]\[zxy\][/tex]

This is the complete mathematical translation of the given phrase.

every 2 liters

Peggy:

90 tea bags

12 liters

You would simplify it by dividing 90 by 15, equaling 6. And 12 divided by 2, also equaling 6. Which would mean they are equal and Peggy's tea is exactly like Kermit's favorite iced tea.

Answer:  The correct choice is

Choice (C)  It is just right.

Step-by-step explanation:  Given that Kermit's favorite iced tea is made with 15 tea bags in every 2 liters of water and Peggy made a 12 liter batch of iced tea with 90 tea bags.

We are to select the correct choice that describes the thinking of Kermit about Peggy's Iced tea.

The ratio of quantity of water and number of tea bags in Kermit's favorite iced tea is given by

[tex]R_k=2:15.[/tex]

And the ratio quantity of water and number of tea bags in Peggy's iced tea is given by

[tex]R_p=12:90=\dfrac{12}{90}=\dfrac{2}{15}=2:15.[/tex]

t = 1; pairs of binomials: (x + 1) and (3x + 8)

t = 2; pairs of binomials: (x + 2) and (3x + 4)

Explanation:

Values of t for which 3(x²) + tx + 8 can be factored into binomials: To factor this expression, we need to identify values of t that allow the expression to be split into two binomials that, when multiplied, give the original expression.

t = 0; pairs of binomials: (x) and (3x + 8)

The area of the copy would be 36 in x16in

The area of the copy of the photograph, with doubled dimensions of 12 inches by 8 inches, is 96 square inches, which is four times the area of the original photograph.

To find the area of a copy of a photograph with dimensions that are double the original, you first find the new dimensions. Since the original photograph is 6 inches by 4 inches, doubling both the length and the width gives us dimensions of 12 inches by 8 inches for the copy.

The area of a rectangle is found by multiplying the length by the width. Therefore, the area of the copied photograph is 12 inches x 8 inches, which equals 96 square inches. This is four times the area of the original photograph since the scale factor for both the length and the width is 2, and the area scales with the square of the scale factor (22).

In conclusion, the area of the copied photograph is 96 square inches. This calculation demonstrates that when you change the linear dimensions of a figure by a scale factor, the area changes by the square of that scale factor.

Answer:

4(x-3)(x+6)

Step-by-step explanation:

We factor out the 4 first since all numbers are divisible by 4. That leaves us with x^2+3x-18.

Then we factor this to get (x-3)(x+6).

So the factored form of the equation is 4(x-3)(x+6)

Step-by-step explanation:

The factors of the equation 4x²+12x -72 will be 4(x-3)(x+6).

A quadratic equation is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.

Factor out the 4 first since all numbers are divisible by 4. That leaves us with x² +3x -18.

4( x² +3x -18 ) = 4 ( x² + 6x - 3x -18 )

                      = 4 ( x(x+6) -3 (x + 6)

                      = 4 ( x + 6 ) ( x - 3 )

Hence, the factors are 4 ( x + 6 ) ( x - 3 ).

Answer:

2x + 3y = -10

Step-by-step explanation:

First convert the line into slope intercept form to find the slope of the line.

2x + 3y = 4

3y = 4 - 2x

y = -2/3x + 4/3

The slope of the line is -2/3. Parallel lines have the same slope so the slope for a line through the point (1,-4) will be -2/3. Substitute m = -2/3 and (1,-4) into the point slope of a line.

[tex]y --4 = -\frac{2}{3}(x-1)\\y + 4 = -\frac{2}{3}(x -1)[/tex]

Now convert the line into standard form by using the distributive property.

[tex]y + 4 = -\frac{2}{3}(x -1)\\y + 4 = -\frac{2}{3}x + \frac{2}{3}\\3y + 12 = -2x + 2\\2x + 3y + 12 = 2\\2x + 3y = -10[/tex]

Answer:

x=37

Step-by-step explanation:

Since this is a right triangle, we can use Pythagorean theorem

a^2 +b^2 =c^2

12^2 +35^2 = x^2

144+1225= x^2

1369 = x^2

Take the square root

sqrt(1369) = sqrt(x^2)

37 = x

Answer:

x = 37

Step-by-step explanation:

Two leg lengths (35 and 12) are given, and the hypotenuse length is to be found.  The Pythagorean Theorem links, these three quantities and enables us to find x quickly and easily:

35² + 12² = x²  →  1225 + 144 = 1369  →  x² = 1369

Find x by taking the square root of both sides:

√(x²) = ±√1369  →  x = ± 37.

Because length is always +, omit x = -37 and keep x = +37.

Answer:

A

Step-by-step explanation:

This is an even polynomial because both ends end up. This means the degree of the polynomial is even. This means b and c are not solutions since their degrees are odd.

To determine between A and D look at the x-intercepts. The x-intercepts of a polynomial graph have a special relationship with its equation. The x-intercepts are the solutions or roots of the factors. This means that when each factor is set equal to 0 and solved, its solution is an x-intercept. Here the x-intercepts are x = -1, 0,3. This means the factors are x(x+1)(x-3).

Notice at x = -1, the function touches but does not cross? This means the factor has an even exponent on it.

So the expression is likely x(x+1)^2 (x-3).

Since only one factor has an exponent, the answer is A.
