Which ordered pair is generated from the equation shown below?

y = 3x + 2

A) (3, 11)
B) (3, 9)
C) (5, 15)
D) (2, 4)

Answers

Answer 1

Answer:

(3, 11)

Step-by-step explanation:

To check the ordered pair from given option .

lets plug in the value of x from the choices given .

If value of y is same a sin ordered pair then that pair is correct answer else it can be concluded that pair is not generated from equation given.

equation: y = 3x + 2

_____________________________________

A) (3, 11)

If we put value of X=3 in equation y = 3x + 2,

then y should be 11

y = 3x + 2

=> y = 3*3+2 = 9+2 = 11 . (This is as expected for ordered pair)

Hence this pair (3, 11) is generated from given equation.

_____________________________________

A) (3, 9)

If we put value of X=3 in equation y = 3x + 2,

then y should be 9

y = 3x + 2

=> y = 3*3+2 = 9+2 = 11 . (This is not as expected for ordered pair(3,9)

Hence this pair is not generated from given equation.

_____________________________________

A) (5, 15)

If we put value of X=5 in equation y = 3x + 2,

then y should be 15

y = 3x + 2

=> y = 3*5+2 = 15+2 = 17 . (This is not as expected for ordered pair(5,15)

Hence this pair is not generated from given equation.

_____________________________________

A) (2, 4)

If we put value of X=3 in equation y = 3x + 2,

then y should be 9

y = 3x + 2

=> y = 3*2+2 = 6+2 = 8. (This is not as expected for ordered pair(2, 4)

Hence this pair is not generated from given equation.

_________________________________________________

Thus, only A) (3, 11) is generated from the equation y = 3x + 2

Cube Roots of Negative Numbers.
Thank you!♡

Cube Roots of Negative Numbers.Thank you!

Answers

Answer:The cube root of a negative number is a complex number because there is no real number that, when cubed, gives a negative result.

To find the cube root of -1, we can express it in exponential form as -1 = 1 * e^(iπ), where i is the imaginary unit and π is pi.

The cube root of -1 can be calculated by applying De Moivre's theorem, which states that (r * e^(iθ))^(1/n) = r^(1/n) * e^(iθ/n), where r is the magnitude and θ is the argument of the complex number.

For n = 3, the cube root of -1 becomes:

(-1)^(1/3) = (1 * e^(iπ))^(1/3) = 1^(1/3) * e^(iπ/3) = e^(iπ/3).

Therefore, the cube root of -1 is e^(iπ/3), which can also be expressed as cos(π/3) + i * sin(π/3).

In trigonometric form, the cube root of -1 is (√3/2) + i * (1/2).

George solved the equation -103 = -2(-7x + 7) + 8x as follows:


-103 = -2(-7x + 7) + 8x

Step 1: -103 = 14x + 7 + 8x

Step 2: -103 = 22x + 7

Step 3: -110 = 22x

Step 4: -5 = x


At which step did he make an error?

Explain the error:

Answers

when multiplying -2 by 7 the answer will be -14 instead of 7 so the answer will be like this
-103 = -2(-7x + 7) + 8x

-103 = 22x - 14
-89 = 22x
x = -4

What is Modulo ?

After dividing one number by another, the modulo operation yields the remainder or signed remainder of the division.

Given:

According to the situation the equation can be

C = 5x + 11y, where x and y are non negative integers.

Now, We will fix y-values first, because there are fewer indices modulo 5:

y = 0 --> 0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55,... 5y

y = 1 --> 11, 16, 21, 26, 31, 36, 41, 46, 51, 56,... 5y + 11

y = 2 --> 22, 27, 32, 37, 42, 47, 52, 57, ...5y + 22

y = 3 --> 33, 38, 43, 48, 53, 58, ...5y + 33

y = 4 --> 44, 49, 54, 59, ...5y + 44

Then, 39 may be verified to be the smallest number that is impossible to obtain.

By examining each index (0, 1,..., 4), we may demonstrate this by observing that for y = 1, 6 is the largest positive integer congruent to 1 mod 5 that cannot be made, 17 is the largest positive number congruent to 2 mod 5, etc.

The largest of these improbable numbers is 39.

We could say that since 40, 41, ..., 44 are all obtainable, then we can induct by adding a multiple of 5 (i.e. if k is possible, so is k+5),

Hence, all amounts greater than 40 cents can be formed.

Point A' will lie at (b) (-2,1) after the transformation.

The coordinates of the triangle are given as:

\(A = (-2,1)\)

\(B = (-1,4)\)

\(C = (-4,5)\)

The rule of reflection over the y-axis is:

\((x,y) \to (-x,y)\)

So, the new coordinate of A is:

\(A =(2,1)\)

The rule of reflection over the x-axis is:

\((x,y) \to (x,-y)\)

So, the new coordinate of A is:

\(A =(2,-1)\)

The rule of 180 degrees rotation is:

\(A = (-2,1)\)
