Answer: B

Step-by-step explanation:

The question asks for [n≥-5] to be true, which means any value that is greater or equal to -5 will be considered.

A. {-5, -5.5, -6}

-5 TRUE

-5.5 FALSE

-6 FALSE

B. {-5, -4.5, -3}

-5 TRUE

-4.5 TRUE

-3 TRUE

C. {-6, 0, 5}

-6 FALSE

0 TRUE

5 TRUE

D. {-6, -7, -8}

-6 FALSE

-7 FALSE

-8 FALSE

As shown above, we can clearly see that Set B is the set that makes the inequality true.

There are 4 white and 8 red roses in a bouquet. Find the ratios. The ratio of the number of red roses to the number of white ros

pychu [463]

Given:

Number of white roses = 4

Number of red roses = 8

To find:

The ratio of the number of red roses to the number of white roses.

Solution:

Using the given information, the ratio of the number of red roses to the number of white roses is

$\text{Required ratio}=\dfrac{\text{Number of red roses}}{\text{Number of white roses}}$

$\text{Required ratio}=\dfrac{8}{4}$

$\text{Required ratio}=\dfrac{2}{1}$

$\text{Required ratio}=2:1$

Therefore, the required ratio is 2:1.

3 + 2x -y =0 -3 -7y = 10x

Answer:

(-1, 1)

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS
Equality Properties

Algebra I

Solving systems of equations using substitution/elimination
Solving systems of equations by graphing

Step-by-step explanation:

Step 1: Define systems

3 + 2x - y = 0

-3 - 7y = 10x

Step 2: Rewrite systems

3 + 2x - y = 0

Add y to both sides: 3 + 2x = y

Step 3: Redefine systems

y = 2x + 3

-3 - 7y = 10x

Step 4: Solve for x

Substitution

Substitute in y: -3 - 7(2x + 3) = 10x
Distribute -7: -3 - 14x - 21 = 10x
Combine like terms: -14x - 24 = 10x
Add 14x on both sides: -24 = 24x
Divide 24 on both sides: -1 = x
Rewrite: x = -1

Step 5: Solve for y

Define original equation: -3 - 7y = 10x
Substitute in x: -3 - 7y = 10(-1)
Multiply: -3 - 7y = -10
Add 3 to both sides: -7y = -7
Divide -7 on both sides: y = 1

Step 6: Graph

Check the solution set.

Given: m∠LOI=38° m∠JOP=84° Find: m∠JKP

grigory [225]

Answer:

84°

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one. Please have a look at the attached photo.

Given that:

∠LOI=38°
∠JOP=84 °

As we can see from the figure that ∠JOP and ∠JKP are on the same segment JP. Hence, ∠JOP and ∠JKP are congruent and the angle of ∠JKP is 84°
