Answer:

05/20 is not an equivalent fraction

Step-by-step explanation:

1) Write each fraction in its simplest form. To do this divide the numerator by the denominator.

04/12 becomes 1/3

07/21 becomes 1/3

05/20 becomes 1/4

09/27 becomes 1/3

2) all the fractions simplify to the same number except 05/20. So, we can conclude that 05/20 is not an equivalent fraction

The equation for the line parallel to given line containing C:

y = 8/9x + 64 / 9

What is Parallel line ?

Parallel lines in geometry are coplanar, straight lines that don't cross at any point. In the same three-dimensional space, parallel planes are any planes that never cross. Curves with a predetermined minimum distance between them and no contact or intersection are said to be parallel.

Given that a line's equation is,

y = 8 / 9x - 7

If we contrast this equation with a line's slope-intercept,

this line's slope = 8/9

Since every line parallel to this one will have a same slope,

The parallel line's slope is equal to

The symbol for the line with the slope 'm' and the coordinates (x', y') is

y - y' = m(x - x')

As a result, the equation of the line through (-1, 8) with a slope will be,

y - 8 = 8/9 (x-1)

y =8/9x - 8/9 - 8

y = 8/9x + 64 / 9

Hence, The equation for the line parallel to given line containing C is

y = 8/9x + 64 / 9

Answer:

x = 15

Step-by-step explanation:

Let's start by copying down the equation.

6 + 4x + 3 = 6x - 21

Let's simplify this equation and we get,

4x + 9 = 6x - 21

Now, we can add 21 to both sides to isolate 6x on one side. Then, we get...

4x + 30 = 6x

Now, we minus 4x from both sides to get rid of it.

Then we get...

2x = 30

Thus, x = 15

6 + 4x + 3 = 6x - 21

We minus (4x+3) on both side.

6 + 4x + 3 - (4x+3) = 6x - 21 - (4x + 3)

6 = 2x - 24
2x = 30
x = 15.

Recheck : 6 + 60 + 3 = 90 - 21
69 = 69 (nice.)

The system of Inequality for the given graph is;

2x + 3y ≥ 12

3x - 5y ≥ 15

Inequalities that use < or > symbols are always plotted with a dashed line while Inequalities that use ≤ or ≥ symbols are always plotted with a solid line.

Now, if the shaded portion is above a dashed line, the the symbol is > but if it is shaded above a solid  line, then the symbol is ≥. In this question, a solid line is used for both equations and shaded above the lines and so we will use ≥.

Equation of Line 1;

x-intercept = 6

y intercept = 4

Slope = -2/3

Thus, using the general equation of slope of line, the equation of this inequality is; 2x + 3y ≥ 12

Similarly, the equation of the second line will be;

3x - 5y ≥ 15

Ellie needs 1.5 gallon of milk (that is 24 cups).

we are given 2 cup = 1 pint

we have 24 cup which will be equal to 24/2 i.e. 12 pint.

we are given 2 pint = 1 quart

we have 12 pint which will be equal to 12/2 i.e. 6 quart

we are given 4 quart = 1 gallon

we have 6 quart which will be equal to 6/4 i.e. 1.5 gallon.

Hence, we know 24 cups of milk is equivalent to 1.5 gallon of milk

Thus, the domain for f(x) is all real numbers greater than or equal to 2.

Answer:

The domain for f(x) is all real numbers greater than or equal to 2.

Step-by-step explanation:

Given function:

[tex]f(x)=2x^2+5 \sqrt{x-2}[/tex]

The domain of a function is the set of all possible input values (x-values).

As the square root of a negative number cannot be taken:

[tex]\implies x-2\geq 0[/tex]

Therefore:

[tex]\implies x-2+2\geq 0+2[/tex]

[tex]\implies x\geq 2[/tex]

Therefore, the domain of the given function is greater than or equal to 2.

The correct option B. It is a one-to-one function; for the given graph.

For given functions f(x) = 3x² - 8 and g(x)=5 - 2x - 2x², f(x) - g(x) = 5x² + 2x - 13

In this question, we have been given two functions f(x) = 3x² - 8 and g(x)=5 - 2x - 2x²

We need to find f(x) - g(x)

We need to subtract function g(x) from function f(x)

= f(x) - g(x)

= 3x² - 8 - (5 - 2x - 2x²)

= 3x² - 8 - 5 + 2x + 2x²

= 3x² + 2x² + 2x - 8 - 5

= (3 + 2)x² + 2x - (8 + 5)

= 5x² + 2x - 13

Therefore, for given functions f(x) = 3x² - 8 and g(x)=5 - 2x - 2x², f(x) - g(x) = 5x² + 2x - 13

Brian will have 46.90 miles to his destination after 41 minutes of driving.

In the question ,

it is given that

Brian has 69 miles left to his destination after 15 minutes of driving

let x denotes the driving time ( in minutes)

and y denote the remaining distance ( in miles )

so the point is represented by (15,69)  

and given that

Brian has 58.8 miles to his destination after 27 minutes of driving

so the second point is (27,58.8).

Since the relationship is given to be linear , hence it will represent a line .

the equation of line passing through the two points (15,69) and (27,58.8) is given by

(y-69)=(58.8-69)/(27-15) * (x-15)

y-69 = -10.2/12 * (x-15)

y-69 = -0.85(x-15)

y-69= -0.85x+12.75

y = -0.85x + 81.75

So , the linear relationship between remining distance and driving time is given by y = -0.85x + 81.75 .

to find miles will he have to his destination after 41 minutes of driving

Substituting x=41 we get

y = -0.85(41) + 81.75

y = -34.85 + 81.75

y = 46.90 .

Therefore , Brian will have 46.90 miles to his destination after 41 minutes of driving.

The longest side of a quadrilateral with length of consecutive even integers is 26 feet.

The lengths of the four sides of a quadrilateral (in feet) are consecutive even integers.

A quadrilateral is a polygon with 4 sides.

Therefore, the sides are consecutive even numbers.

Hence,

smallest side = x

Therefore, perimeter is the sum of the whole sides of the quadrilateral.

x + x + 2 + x + 4 + x + 6 = 92

4x + 12 = 92

4x = 92 - 12

We can show that x² + 5x = 3 given the dimensions of the rectangle that has an area of 9 cm² as explained below.

To find the area of a rectangle, use the formula given below:

Area of a rectangle = (length)(width).

Given the parameters:

To show that x² + 5x = 3, plug in the values into the formula for the area of a rectangle:

(x + 3)(x + 2) = 9

Apply the distributive property of equality

x(x + 2) + 3(x + 2) = 9

x² + 2x + 3x + 6 = 9

Combine like terms:

x² + 5x + 6 = 9

Add -6 to both sides of the equation

x² + 5x + 6 - 6 = 9 - 6 [subtraction property of equality]

x² + 5x = 3

Thus, if the area of the rectangle with the given dimensions is 9 cm², then we can show that, x² + 5x = 3 as explained above.

In this instance, the next word in the sequence is obtained by adding 2 to the previous term. To put it another way, a n = a 1 + d (n – 1) This is the arithmetic sequence’s formula.

Firstly, we have to find the initial phrase in a given series. Thereafter we have to find the shared difference between the following phrases in the sequence. For an explicit rule, replace the general form with the first term and common difference.

The solution for the expression x² = 12 will be x = ±2√3.

The expression is given in the form of square of a variable x which is equal to 12. This expression does not form a perfect square as the constant term is not a perfect square number. A perfect square is a number which is expressed as the square of whole number, or a number multiplied by itself twice. Here, we are given that x² = 12. We take square root of the expression on both the sides then,

√x² = √12

x = √(2×2×3)

x = ±2√3

We use the sign '±' because any number which when expressed in variable form comes out of the square root then it can be positive or negative,

The rational equivalent to 0.86 can be written as 43/50.

A rational number may be defined as the number which can be expressed in the form of p/q where p and q are integers, and the term q cannot be equal to zero. It can be either positive or negative or both. We can also say that any fraction which does not have zero in the denominator is called a rational number. Zero can also be regarded as a rational number as it can also be represented as a fraction. For example, 0/2, 0/5.  In order to write 0.86 as a rational number, we have to convert it in fraction form. In fraction form it can be written as

0.86 = 86/100

This is also a rational number, but we simplify it further and we get
