Is (-2, 6) a solution to this system of linear equations? (HINT: Substitute x
with-2 and y with 6 in both equations, then simplify). *

Is (-2, 6) A Solution To This System Of Linear Equations? (HINT: Substitute Xwith-2 And Y With 6 In Both

Answers

Answer 1

Answer:

1st Equation: -8x + y = 22

At (-2,6)

(-8*-2)+ 6 =16+6= 22: That is correct

2nd Equation: -8x - y =10

At (-2,6)

(-8*-2)-6= 16-6= 10: That is correct

Both are correct.

Hope it helps you.

company that manufactures a popular multivitamin wanted to determine whether their multivitamin had any side effects. For its initial study, the company chose 2000 individuals to take one of their multivitamin tablets per day for one year. Scientists from the company surveyed the participants to determine whether they had experienced any side effects. The greatest problem with this procedure is that A) only one brand of vitamin was tested B) the study lasted only one year C) the sample size was not large enough D) no control group was used

Answers

Answer:

Option D

Step-by-step explanation:

In this experiment, It would have been scientific to compare the result of the experiment on the experimental group(taking the multivitamin) with the control group (Taking no medicine)

Without a control group, a defined impact of multivitamin over the experimental group cannot be deduced.

Hence, option D is correct

Uma loja de brinquedos tem uma vitrine com várias prateleiras contendo 21 bonecas, 18 carrinhos de brinquedo e 15 bonecos de ação. Cada prateleira tem 18 brinquedos e todas as prateleiras são usadas

Answers

Responder:

3

Explicação passo a passo:

Dado :

Total de brinquedos:

Bonecas = 21

Carros Roy = 18

Figuras de ação = 15

Número total de brinquedos = (21 + 18 + 15) = 54 brinquedos

Número de brinquedos por prateleira = 18

Número de prateleiras:

Número total de brinquedos / número de brinquedos por prateleira

Número de prateleiras = 54/18

Número de prateleiras = 3

3 prateleiras estão na vitrine

As we all know, Pinocchio’s nose grows when he tells a lie.

So if he said “my nose will grow now” – if his nose does grow that would mean he wasn’t lying, but if he wasn’t lying, his nose wouldn’t grow.

But then his statement would be a lie… so his nose would grow.. but then the statement wouldn’t be a lie… so his nose wouldn’t grow… but yeah, you get the idea..

Basically, his nose would have to grow to make Pinocchio’s statement not a lie, but then it can’t grow otherwise the statement would not be a lie.

Carole worked her 40 regular hours last week plus 6 overtime hours at the time-and-a-half rate. Carole's regular hourly rate is $11.50. How much did Carole get paid last week?

Answers

Answer:

$563.50

Step-by-step explanation:

The computation of the amount that should be paid to Carole last week is shown below

Since she worked 40 regular hours and 6 overtime hours

For regular hours, the wage rate is $11.50

And, for overtime it would be

= $11.50  + $11.50 ÷ 2

= $11.50 + $5.75

= $17.25

So, the amount that should be paid is

= 40 × $11.50 + 6 × $17.25

=  $460  + $103.50

= $563.50

If –8x + 2y = -4 is a true equation, what would be the value of 40x – 10y?

If u need to find the values for X & Y I believe this is the right answer

X = 1 —— Y = 2
-8x + 2y = -4

Override the equals and to String methods from class Object. List of Bulbs Create a class called BulbNode which has fields for the data (a Bulb) and next (BulbNode) instance variables. Include a one-argument constructor which takes a Bulb as a parameter. (For hints, see the PowerPoint on "Static vs. Dynamic Structures".) public BulbNode (Bulb b) {...} The instance variables should have protected access. There will not be any get and set methods for the two instance variables. Create an abstract linked list class called BulbList. This should be a linked list with head node as described in lecture. Modify it so that the data type in the nodes is Bulb. The no-argument constructor should create an empty list with first and last pointing to an empty head node, and length equal to zero. Include an append method in this class. Create two more linked list classes that extend the abstract class BulbList: One called UnsortedBulbList and one called SortedBulbList, each with appropriate no-argument constructors. Each of these classes should have a method called add(Bulb) that will add a new node to the list. In the case of the UnsortedBulbList it will add it to the end of the list by calling the append method in the super class. In the case of the SortedBulbList it will insert the node in the proper position to keep the list sorted by wattage. Instantiate two linked lists, and for every Bulb read from the file, add it to the unsorted and sorted lists using the add method.
