To find the difference between two numbers, you subtract them from eachother. 6 - -3 is the same as 6+3, so the difference between the two temperatures is 9 degrees.

What is the value of y in the equation 5x+2y=20 when x = 0.3?
zavuch27 [327]

Answer:

y = 9,25

Step-by-step explanation:

(5*0,3) + 2y = 20 (x=0,3)

1,5 + 2y = 20 .  (-1,5)

2y = 18,5 ( /2)

y = 9,25

Modular arithmetic<br> Pls a little explaine it
fredd [130]

Step-by-step explanation:

(72)¹⁴³ ≡ x (mod 7)

Since 72 ≡ 2 (mod 7),

72³ ≡ 2³ (mod 7) ≡ 1 (mod 7).

Therefore (72)¹⁴³ = (72³)⁴⁷ * (72²)

≡ 1⁴⁷ * 4 (mod 7) ≡ 4 (mod 7).

The answer is A.

X^5 + 243 divided by x+3
ch4aika [34]
-3   |  1   0   0   0   0   243  \longleftarrow coefficients of the polynomial you're dividing
.     |                                   \longleftarrow drop down the leading coefficient
- - - - - - - - - - - - - - - - - - -
.     |  1

On the left side of the frame, we write -3 because we're dividing by x+3=x-(-3). (The algorithm is followed for division of a polynomial by a factor of x-c.) Since we're dividing a degree 5 polynomial by a degree 1 polynomial, we expect to get a degree 4 polynomial.

-3   |  1   0   0   0   0   243
.     |      -3                         \longleftarrow multiply -3 by 1, write in next column, add to 0
- - - - - - - - - - - - - - - - - - -
.     |  1  -3

Repeat step for the remaining columns.

-3   |  1   0   0   0   0   243
.     |      -3   9
- - - - - - - - - - - - - - - - - - -
.     |  1  -3   9

-3   |  1   0   0      0   0   243
.     |      -3   9   -27
- - - - - - - - - - - - - - - - - - -
.     |  1  -3   9   -27

-3   |  1   0   0      0     0   243
.     |      -3   9   -27   81
- - - - - - - - - - - - - - - - - - - - -
.     |  1  -3   9   -27   81

-3   |  1   0   0      0     0    243
.     |      -3   9   -27   81  -243
- - - - - - - - - - - - - - - - - - - - -
.     |  1  -3   9   -27   81       0

which translates to

\dfrac{x^5+243}{x+3}=x^4-3x^3+9x^2-27x+81

So the bottom row of the frame gives the coefficients of each term in the quotient by descending order. Since the last coefficient is 0, this means the remainder upon division vanishes, i.e. x^5+243 is exactly divisible by x+3.

- - -

Another way to get the same result is to use a well-known result: for a+b\neq0,

a^5+b^5=(a+b)(a^4-a^3b+a^2b^2-ab^3+b^4)\implies\dfrac{a^5+b^5}{a+b}=a^4-a^3b+a^2b^2-ab^3+b^4

and in this case a=x and b=3
