Answer:

(3, - 2 ) and (- 2, 2 )

Step-by-step explanation:

(8)

2x + y = 4 → (1)

x + 3y = - 3 → (2)

Multiplying (2) by - 2 and adding to (1) will eliminate the x- term

- 2x - 6y = 6 → (3)

Add (1) and (3) term by term to eliminate x

0 - 5y = 10

- 5y = 10 ( divide both sides by - 5 )

y = - 2

Substitute y = - 2 into either of the 2 equations and solve for x

Substituting into (1)

2x - 2 = 4 ( add 2 to both sides )

2x = 6 ( divide both sides by 2 )

x = 3

solution is (3, - 2 )

---------------------------------------------

(9)

3x + 5y = 4 → (1)

x + 3y = 4 → (2)

Multiplying (2) by - 3 and adding to (1) will eliminate the x- term

- 3x - 9y = - 12 → (3)

Add (1) and (3) term by term to eliminate x

0 - 4y = - 8

- 4y = - 8 ( divide both sides by - 4 )

y = 2

Substitute y = 2 into either of the 2 equations and solve for x

Substituting into (2)

x + 3(2) = 4

x + 6 = 4 ( subtract 6 from both sides )

x = - 2

solution is (- 2, 2 )

Answer:

I think that Ishaan is 6

Step-by-step explanation:

I am very sorry if it is wrong

If you're wanting it alone just with the exponents, here is how you're going to do it:

Technically, the 2 alone has a power, and it's simply just one. When exponents are being used in numbers multiplying together, they add.

So, to simplify this it'd be 2^5.

If you're wanting the actual answer, you would do exponents first. Remember that exponents are just the number being multiplied by itself x times:

                                   2 x 2 x 2 x 2 = 16

Now we just need to multiply this by 2 and you'll get 32.

OR, if you do the 2^5, you'll still get 32!

Answer:

A line of best fit is drawn through a scatterplot to find the direction of an association between two variables. This line of best fit can then be used to make predictions. To draw a line of best fit, balance the number of points above the line with the number of points below the line.

Answer:

x = -2

y = 9

Step-by-step explanation:

y = -3x + 3

y = 5x + 19

We can put one y as another:

-3x + 3 = 5x + 19

-8x = 16

x = -2

And now let's check using x = -2

y = (-3 * -2) + 3

y = (5 * -2) + 19

y = 6 + 3

y = -10 + 19

y = 9

y = 9

x=2.5

Step-by-step explanation:

x+3.5/4=2(2x+2)/4

x+3.5=2x+2/2

x-2x+3.5=1

-x=(-3.5)+1

-x=(-2.5)

-x/(-1)=(-2.5)/(-1)

x=2.5

Obviously, there is 784/7, but there is a less common kind of expression that also works. Since a fraction is similar to a division expression, you can flip 7 to make 1/7. The other expression could be 1/7 x 784.

So the two expressions could be 784/7 and 1/7 x 784

Answer:

17.2 cm

Step-by-step explanation: Each side would be 19 cm since a triangle has three sides. Next, we will use pythagorean theory. Since the equation would be a^2 + b^2 = c^2. Since 19^2 is 361 and is getting subtracted by 64 (we get it because at the bottom, we have to split it. also, 8 squared is 64). Then we get 297, which the base root with one number behind the decimal would be 17.2 cm.

Answer:

48.3

Step-by-step explanation:

→ See what side is not given

Opposite

→ Find a triangle with out an O in it

Cos = Adjacent / Hypotenuse

→ Make what you want to find the subject

Hypotenuse = Adjacent / Cos

→ Substitute the numbers into the formula

41 / cos (32) = 48.3

Answer:

d. a power analysis; tells the researcher the number of participants needed for trustworthy results.

Step-by-step explanation:

A control experiment can be defined as an experiment in which a condition assumed to be a probable cause of the effect is being compared to the same situation by the scientist without involving or using the suspected condition.

A hypothesis is considered to be tentative or an educated guess and can be defined as a testable explanation for an observation or a scientific problem. An example of a hypothesis is saying, Corona virus is caused by the introduction of the "5G" technology.

This ultimately implies that, for any hypothesis to be acceptable in science, it must be supported by observations and the results of control experiments; this give rise to factual informations, theories and by extension solutions to problems.

Before hypothesis testing and at the beginning of a study, a researcher is advised to conduct a power analysis because it tells the researcher the number of participants needed for trustworthy results.

A power analysis should always be conducted before the collection of data because it will help you as a researcher to determine the smallest sample size that's accurate enough to detect the effect of a specific test at the desired statistical significance level.

Answer:

it's only the last two

Step-by-step explanation:

3x + 2 = 25

3x + 2 - 2 = 3x

25 - 2 = 23

3x = 23

3x / 3 = x

23 / 3 = 7 2/3

x = 7 2/3 not this one

x/3 + 7 = 8

x/3 + 7 - 7 = x/3

8 - 7 = 1

x/3 = 1

x/3 * 3 = x

1 * 3 = 3

x = 3 not this one

4 + 5x = 18

4 + 5x - 4 = 5x

18 - 4 = 14

5x = 14

5x / 5 = x

14 / 5 = 2 4/5 not this one

24 - 2x = 13

24 - 2x - 24 = -2x

13 - 24 = -11

-2x = -11

-2x / -2 = x

-11 / -2 = 5 1/2 not this one

81/x - 3 = 6

81x - 3 + 3 = 81/x

6 + 3 = 9

81/x = 9

81/x * x = 81

9 * x = 9x

81 = 9x

81 / 9 = 9

9x / 9 = x

9 = x this one

2x - 3 = 15

2x - 3 + 3 = 2x

15 + 3 = 18

2x = 18

2x / 2 = x

18 / 2 = 9

x = 9 this one

Answer:

x = 12 and y = 31

Step-by-step explanation:

Hey There!

So the two angles with x are interior angles meaning that they are congruent

So to solve for x we use the equation

3x+17=5x-7

step 1

add 7 to each side

17+7=24

-7+7 cancels out

now we have

3x+24=5x

step 2 subtract each side by 3x

3x-3x cancels out

5x-3x=2x

were left with

2x=24

final step divide each side by 2

24/2=12

2/2 cancels out

x=12

now we plug it into one of the expressions

3x12=36

36+17=53

the angle that is equal to 53 is supplementary to the angle with y meaning that they add up to 180

so to solve for y we use this equation

180=4y+3+53

step 1 combine like terms

53+3=56

now we have

180=4y+56

step 2 subtract each side by 56

180-56=124

124=4y

step 3 divide each side by 4

124/4=31

y=31

so we can conclude that

x=12 and y = 31

Step-by-step explanation:

step 1. y = mx + b. (slope intercept form)

step 2. y = (rise/run)x + (y intercept)

step 3. y = (5/3)x + 0

step 4. y = (5/3)x

Step-by-step explanation:

how many pencils will be left over?=144-140

=4

After sharing 144 pencils equally among 5 people they left with 4 pencils.

Given that, Terry has a box of 144 colored pencils.

The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items.

Terry and 4 of his friends share the pencils equally

So, including terry there are 5 people

Here,

5|144|28

  10
______

    44
    40
______
      4

Each of the them get 28 pencils, after sharing equally, they left with 4 pencils

Therefore, after sharing 144 pencils equally among 5 people they left with 4 pencils.
