The system of Inequality for the given graph is;

2x + 3y ≥ 12

3x - 5y ≥ 15

How to Interpret Inequality graph?

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;

The area of a rectangle ABCD is 9cm².
Show that x² + 5x = 3

Answers

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

How to Find the Area of a Rectangle?

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

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

Given the parameters:

Area of rectangle ABCD = 9 cm²Length of the rectangle = BC = (x + 3) cmWidth of the rectangle = AB = (x + 2) cm

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.

From the given linear equation graph, we can tell that the equation of the line in slope intercept form is; y = 1.2x + 3

How to Interpret Linear Equation Graph?

The general form of equation of a line in slope intercept form is;

y = mx + c

where;

m is slope

c is y-intercept

From the given graph, we see that;

y - intercept = 3

x - intercept = -2.5

Now, we can find the slope by taking two coordinates;

(-2.5, 0) and (0, 3)

Slope = (3 - 0)/(0 - (-2.5))

Slope = 3/2.5

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

Answers

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,

Thus, the value of x is ±2√3.

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

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

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.

which rational is qvuivalent to 0.86

Answers

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
