The inequalities are solved below

What are inequalities?

A connection in mathematics that compares two numbers or other mathematical functions in an unequal way is known as an inequality. It is most frequently used to compare the sizes of two numbers on the number line. To indicate various sorts of inequalities, a variety of notations are employed. The following characteristics control inequalities. Any of these characteristics are also true if monotonic functions are restricted to strictly monotonic functions and all non-strict inequalities ( and ) are replaced by their equivalent strict inequalities ( and >). On each side of an inequality, a common constant c can be added to or removed from.

The inequalities are solved below

-2x-7>1                                   x-2≥-1

or, -2x>1+7                            or, x≥-1+2

Compound interest formula:

A = P (1+r/n)^nt

Where:

A = total amount

P = principal investment

r= interest rate in decimal form = 2/100 = 0.02

t= years

n= number of compounding periods in a year= 12

Replacing:

A = 30,000 (1+0.02/12)^4x12

A = 30,000 (1.001666667)^48

A= 32,496.45

The length has a value of  9 meters

From the question, we have the following parameters that can be used in our computation:

Length = 5 meters less twice it’s width

This means that

Length = 2Width - 5

The perimeter is given as

Perimeter = 38 meters

The perimeter is calculated as

Perimeter = 2 x (Length + Width)

So, we have

2 x (2Width - 5 + Width) = 38

Divide by 2

2Width - 5 + Width = 19

This gives

3Width= 21

Divide

Width - 7

Recall that Length = 2Width - 5

So, we have

Length =  2 * 7 - 5

Evaluate

Length =  9

Hence, the length is 9 meters

B

If two lines are perpendicular, it means that the slope of one line is equal to the negative reciprocal of the slope of the other line. Given a value, a/b, the negative reciprocal of a/b is - b/a.

From the information given, the slope of the red line is 2/5. This means that the slope of the green line which is perpendicular to the red line is - 5/2

Option D is correct

The system of equations that could be used to determine the number of drinks and the number of tacos that Jordan bought are 2.5x + 2y = 26 and y = x + 4.

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

Let's assume that number of drinks that Jordan and his children bought is x while the number of tacos is y.

The cost of drinks = 2.50x

Cost of tacos = 2y

Total cost 2.5x + 2y

2.5x + 2y = 26

Given that,

He bought 4 more tacos than drinks.

Therefore,

y = x + 4.

Hence "The system of equations that could be used to determine the number of drinks and the number of tacos that Jordan bought are 2.5x + 2y = 26 and y = x + 4".

5. The two triangles are similar. The value of x = 12.

6. The information cannot be used to show that the triangles are similar triangles.

Two triangles are similar to each other if they have the same shape but different sizes, in order words, they must have the same corresponding angle measures but different corresponding side lengths that are proportional to each other.

5. In the first figure, we see that there are two pairs of corresponding congruent angles (a pair of right angles and a pair of vertical angles in both triangles), but different corresponding side lengths.

Therefore, based on the AA similarity theorem that says two triangles are similar of they have two pairs of congruent sides, we can prove that both triangles are similar to each other.

Therefore:

x/9 = 20/15

15x = (9)(20)

15x = 180

15x/15 = 180/15

x = 12

6. The second image shows that the two triangles share a common side, which means they have a pair of corresponding sides that are congruent. Therefore, the information given cannot be used to prove they are similar triangles.

Answer:

Sum of angles in a triangle add up to 180°.

x = 180 - 64 - 40

= 76°

Based on the vertices of the triangle, the area of the triangle can be found to be 8 cm²

First, find the lengths of JK, KL, and JL. When given vertices, you can find the length of a line by the formula:

= √ ( (x₂ - x₁)² + (y₂ - y₁)²)

The length of JK is therefore 2.83 units

The length of KL is therefore 5.66 units

The length of JL is therefore 6.32 units.

Given these units, the area of the triangle can be found by the formula:

= √ s(s - a) ( s - b) ( s - c)

Where:

s = semi perimeter

a, b, and c are the sides of the triangle which are JK, KL, and JL.

The semi-perimeter can be found by the formula:

= ( a + c + c) / 2

= 15.47 / 2

= 7.74

The area of the triangle is therefore:

= √ s(s - a) ( s - b) ( s - c)

= √ 7.74 (7.74  - 2.83) ( 7.74 - 5.66) ( 7.74 - 6.32)

= 8 cm²

Answer: When you graph part a, it has a negative slope.

Step-by-step explanation:

The image of the point after the dilation is (-2, -1)

Dilation is the process of altering the side length of a shape or a function

From the question, the given parameters are:

Point =  (-8, -4)

The scale factor of dilation is given as

Scale factor = 1/4

Mathematically, this transformation can be represented as

(x, y) = k(x, y)

Where k = 1/4 i.e. the scale factor

So, we have

(x, y) = (kx, ky)

This gives

(x, y) = (1/4x, 1/4y)

When represented as an equation, we have

Image = 1/4 * Point

Substitute the equation Point =  (-8, -4) in the equation Image = 1/4 * Point

So, we have the following equation

Image = 1/4 * (-8, -4)

Evaluate the product

Image = (-2, -1)

Hence, the image is (-2, -1)

The values of x and y in the triangle are 15 and 88 degrees.

A triangle is a polygon with 3 sides. The sum of angles in a triangle is 180 degrees.

A triangle can be classified base on its sides and angles as equilateral triangle, isosceles triangle and scalene triangles.

An equilateral triangle has three of its sides and angles equal to each other.

An isosceles triangle has 2 sides and angles equal to each other.

A scalene triangle has no sides equal to each other.

Therefore,

The other triangle on the left side is an equilateral triangle.

Therefore, all it sides and angles are equal.

Hence, each angle of the triangle is 60 degrees.

A traversal line cut across the sides of the parallel lines of the triangles formed.

Therefore,

60° = 4x

x = 60 / 4

x = 15

Therefore,

60 + y + 32 = 180(sum of angles in a triangle)

The value of x that makes the equation 2x+5 = 1.99x + 22 is 1700

The equation is

2x+5 = 1.99x+22

First we have to rearrange the given term and combine the like terms, then we have to find the value of x

Move 1.99x to left hand side of the equation and move 5 to the right hand side of the equation

2x+5 = 1.99x+22

2x-1.99x = 22-5

We have to do the subtraction in like  terms

(2-1.99)x = 22-5

0.01x = 17

Move the number 0.01 to the right hand side of the equation

Inequality:

Inequality means the relationship between two values that are not equal is defined by inequalities which means they are not equal.

Given,

Here we have the two triangles with some angle values.

Now, we need to find the inequality of these triangle.

To find the inequality of the triangle first we have to write down the values provided, they are,

77, 11x - 33, 68°, 32°

Through this we have identified that, the value of x is lies in between 68° and 32°.

So, it ca be written as,

32° < x < 68°

The next this is to use the triangle inequality theorem, that is,

"The sum of any two sides of a triangle is greater than or equal to the third side; in symbols, a + b ≥ c."

Therefore, based on the given equation we have written it as,

11x - 33 ≥  77
