Step-by-step explanation:

Step-by-step explanation:

Therefore , the solution to the given problem of inequality comes out to be Part a:where x is the no of apples and y is the no of grapes , Part b:Inequality sign and Part c:  ordered pair (3, −4) isn't solution.

An unbalanced connection between two expressions or values is referred to in mathematics as an inequality. So, inequity results from imbalance. In mathematics, an inequality defines the connection between two non-equal quantities. Egality and inequality do not mean the same thing. Use the not equal sign whenever two values are not equal (). It is possible to compare values of any size using a variety of inequalities. By changing both sides until only the variables are left, it is possible to solve many straightforward inequality problems.

Here,

Given :  3x + 4y ≤ 20.

where x is the no of apples

and y is the no of grapes

Thus,

Part a:

where x is the no of apples

and y is the no of grapes

Part b:

Inequality signs means that 20 will be the maximum amount of the no of apples and no of grapes summation.

Part c: ordered pair (3, −4)

Thus,

putting in the inequality we find:

=> 3(-3)+ 4(-4)

=> -6 -16

=> -22

Thus , it is not a solution for inequality.

Therefore , the solution to the given problem of inequality comes out to be Part a:where x is the no of apples and y is the no of grapes , Part b:Inequality sign and Part c:  ordered pair (3, −4) isn't solution.

Answer: 290 yd^2

Step-by-step explanation:

Tip: split the shapes into areas that are easier to compute

Rectangle 1 = bh = 10yd x 28 yd = 280 yd^2

Rectangle 2 = bh = 2yd x (10-5)yd = 10 yd^2

280 yd^2 + 10 yd^2 = 290 yd^2

Answer:

Step-by-step explanation:

the two diagonals of a rectangle have the same middle point

middle point

x = (2-4)/2 = -1

y = (1+4)/2 = 5/2

The diagonal BD must have the same middle point, so we can find vertex D in this way

(x +2)/2 = -1

x+2 = -2

x = -4

(y+4)/2 = 5/2

y+4 = 5

y = 1

fourth vertex :  (-4, 1)

2) for find the first dimension we can use this formula

|y2 - y1| = |4-1| = 3

for find the second we can use this one:

|x2-x1| = |-4-2| = |-6| = 6 (a dimension can’t be negative)

3)

A = dimension 1 x dimension 2 =  3 x 6 = 18

Answer:

4x + 3

10x² - 7x + 3

18x² - x + 5

Step-by-step explanation:

A polynomial must consist of 2 terms, one with a variable ( x ) and one as a constant ( any number )

An example of a number with a variable is 4x

An example of a constant is 3

add the two together 4x + 3 and you get a polynomial

More examples are 5x + 9 or -2x - 8

Polynomials can have more than 2 terms. ( the third term has an exponent and variable )

An example of a polynomial with more than 2 terms  is 10x² - 7x + 3

The == operator determines if two operands are equivalent in terms of value. The === operator determines if two operands are equivalent in terms of value and datatype.

The assignment operator = is straightforward. The left side operand receives values from the right side operands.

On the other hand, == determines whether or not the values of two operands are equal.

The Python is operator determines if two variables point to the same memory item as opposed to the == operator, which compares the value or equality of two objects. This implies that you should almost always employ the equality operators == and != Difference between == and = in Python.

A single equal sign is used to assign a value to a variable in Python and many other programming languages, whereas two successive equal signs are used to determine if two expressions provide the same result.

Answer:

Three consecutive even integers can be represented by x, x+2, x+4. The sum is 3x+6, which is equal to 108. Thus, 3x+6 = 108.

Answer: 108° ; 165°

Step-by-step explanation:

180(n - 2) is the formula to figure out the total degrees in a polygon.

A pentagon has 5 sides, so:

180(5-2) = 180(3) = 540°

Divide the total degrees by the number of angles (a pentagon has 5 angles):

540° ÷ 5 = 108°

24-gon:

180(24 - 2) = 180(22) = 3960°

3960° ÷ 24 = 165°

Answer: 108° ; 165°

Step-by-step explanation:

180(n - 2) is the formula to figure out the total degrees in a polygon.

A pentagon has 5 sides, so:

180(5-2) = 180(3) = 540°

Divide the total degrees by the number of angles (a pentagon has 5 angles):

540° ÷ 5 = 108°

24-gon:

180(24 - 2) = 180(22) = 3960°

3960° ÷ 24 = 165°

The value of the expression using the distributive property is 5x + 50.

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.

We have,

5 (x - 10)

The distributive property of multiplication over addition states that,

a x (b +  c) = a x b + a x c

Now,

5 (x - 10)

= 5x + 5 x 10

= 5x + 50

Thus,

The expresssion is 5x + 10

Answer:

It could be 3x - 3

Step-by-step explanation:

The numerical coefficient in 3xy is 3.

In algebraic expressions, terms are made up of coefficients and variables. A coefficient is a numerical value that multiplies a variable or a set of variables. In the term 3xy, the numerical coefficient is the number that appears in front of the variable (x and y) and it's 3 in this case.

It is used to indicate the degree of the term or the number of times the variable is present in the term. In this case, it is indicating that the variable x and y are present three times in the term.

It's important to note that if there is no coefficient before the variable, it is assumed to be 1. It's also noteworthy that the coefficient can be a whole number, a fraction, or even a variable, but in this case it is a whole number. Understanding the concept of coefficient is very important in understanding algebraic equations and expressions.

The numerical coefficient in 3xy is 3.

Answer:

x = 14

Step-by-step explanation:

Vertical angles are congruent ( equal to each other )

If ∠A and ∠B are vertical angles

Then 5x + 2 = 6x - 12

                     ^ ( Note that we just created an equation that we can use to                                   solve for x )

The rest comes down to basic algebra

5x + 2 = 6x - 12

step 1 subtract 5x from each side

5x - 5x cancels out

6x - 5x = x

we now have 2 = x - 12

step 2 add 12 to each side

- 12 + 12 cancels out

2 + 12 = 14

we're left with x = 14

Determine the relationship between given lines

(a)

[tex]y = -\frac{2}{5}x + 3[/tex]

and

[tex]y = \frac{2}{5}x + 7[/tex]

An equation written in form: [tex]y=mx + b[/tex] has the slope:

[tex]m \to slope[/tex]

So, in both equations:

[tex]m_1 = -\frac{2}{5}[/tex]

[tex]m_2 = \frac{2}{5}[/tex]

For both lines to be parallel

[tex]m_1 = m_2[/tex]

This is false in this case, because:

[tex]-\frac{2}{5} \ne \frac{2}{5}[/tex]

For both lines to be perpendicular

[tex]m_1 * m_2 = -1[/tex]

This is false in this case, because:

[tex]-\frac{2}{5} * \frac{2}{5} \ne -1[/tex]

(b)

[tex]5y + 2x = -10[/tex]

and

[tex]-5x + 2y = 4[/tex]

Write equations in form: [tex]y=mx + b[/tex]

[tex]5y + 2x = -10[/tex]

[tex]5y = -2x +10[/tex]

Divide by 5

[tex]y = -\frac{2}{5}x +2[/tex]

[tex]-5x + 2y = 4[/tex]

[tex]2y = 5x + 4[/tex]

Divide by 2

[tex]y = \frac{5}{2}x + 2[/tex]

In both equations:

[tex]m_1 = -\frac{2}{5}[/tex]

[tex]m_2 = \frac{5}{2}[/tex]

For both lines to be parallel

[tex]m_1 = m_2[/tex]

This is false in this case, because:

[tex]-\frac{2}{5} \ne \frac{5}{2}[/tex]

For both lines to be perpendicular

[tex]m_1 * m_2 = -1[/tex]

This is true in this case, because:

[tex]-\frac{2}{5} * \frac{5}{2} = -1[/tex]
