Answer:

x ≤ -5

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Define Inequality

-4x + 10 ≥ 5x + 55

Step 2: Solve for x

Add 4x on both sides:                    10 ≥ 9x + 55Isolate x term:                                 -45 ≥ 9xIsolate x:                                          -5 ≥ xRewrite:                                           x ≤ -5

Here we see that any value x smaller than or equal to -5 would work as a solution to the inequality.

which ordered pair makes both of these equations true?
A. (-9,25)
B. (-3,-13)
C. (2,-3)
D. (3,-1)
E. (9,11)

Answers

D is the answer im sure

Answer:

D. (3, -1)

Step-by-step explanation:

y = 2x - 7 and 4x + y = 11 are two given equation

Now, Name the equation

y = 2x - 7 ...(1)

4x + y = 11 ...(2)

Then, Put the value of y in equation (2)

4x + y = 11

4x + (2x - 7) = 11

4x + 2x - 7 = 11

6x - 7 = 11

6x = 11 + 7

6x = 18

x = 18/6

x = 3

Here, put the value of x in equation (1)

y = 2x - 7

y = 2(3) - 7

y = 6 - 7

y = - 1

Thus, (3, - 1) pair makes both of these equations true

Answers

Answer:

18 pounds

Step-by-step explanation:

assuming a 3:4 rate

24 Euros is

24/4 * 3 = 18 pounds

The solution is £ 18

The value of €24 in pounds is 18 pounds or £ 18

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the value of £3 be = €4

So , the equation will be

The value of €1 = £ ( 3/4 )

So , the value of €24 is calculated by the equation

The value of €24 in pounds = value of €1 x 24

Substituting the values in the equation , we get

The value of €24 in pounds = £ ( 3/4 ) x 24

The value of €24 in pounds = £ 3 x 6

The value of €24 in pounds = £ 18

Therefore , the value of €24 in pounds is £ 18

Hence , The value of €24 in pounds is 18 pounds or £ 18

Select the correct answer. Celeste can spend no more than $30 to quinoa and rice. She will pay $5 per pound for quinoa and $2 per pound for rice. which graph best represents the number of pounds of quinoa and the number of pounds of rice celeste can buy?

Answers

Answer:

5x+2y<=30

Step-by-step explanation:

Inequalities help us to compare two unequal expressions. The graph for the inequality can be made as shown below.

What are inequalities?

Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.

As per the graph let the number of pounds of quinoa be represented by x and the number of pounds of rice Celeste can buy be represented by y.

Therefore, the expression that can represent the number of pounds that Celeste can buy is,

5x + 2y

Also, it is given that Celeste can spend no more than $30. Therefore, the inequality can be written as,

5x + 2y ≤ 30

Now the graph for the inequality can be made as shown below.

When you graph an inequality, you used a closed dot when you use which
symbols?

Answers

You use a closed dot with the greater than or less than with the line under the symbol or the greater than or equal to or the less than or equal to symbols. The line indicates a closed dot.

You should only use a closed dot for the symbols ≤ and ≥.

When you should use a closed dot?

There are two types of dots used when graphing inequalities, closed and open.

We use closed dots when the value where the dot is, is a solution.We use open dots when the velue where the dot is, is not a solution.

So, for exampe in:

x > 3.

We would put an open dot at 3, because the value x = 3 is not a solution, but all the values at the right of the 3 are solutions.

In the other hand, for:

x ≥ 3

Now 3 is in fact a solution, so here we should use a closed dot.

Then, answering the question.

"When you graph an inequality, you used a closed dot when you use which symbols?"

The ≤ and ≥ symbols.
