Answer:

y = x+2

Step-by-step explanation:

When x = 0, y =2

So, y = 0 + m

2 = 0 + m

2 = m

When x = 1, y =3

y = x + m

3 = x + 2

-2 -2

1 = x

Examine parallelogram ABCD below.

gtnhenbr [62]

Given that,

∠C = (6x-21)° and ∠A = (4x+11)°

To find,

Choose the correct option.

Solution,

For a parallelogram, the opposite angles are equal. ATQ,

(6x-21)° = (4x+11)°

Taking like terms together,

6x-4x = 21 + 11

2x = 32

x = 16

∠C = (6x-21)° = 6(16) -21 = 75°

So, ∠A = 75°

So, ∠A = ∠C = 75°. Hence, the correct option is (B).

Sphinxa [80]

Hey there! Let’s solve the question first.

(6^4)^-3= 4.593 or 4.6

The reason behind this, 6^4=1296^-3

And 1269^-3= 4.593 or 4.6

Hope this helps!

Factorize that x^4+4y^4

ipn [44]

Answer:

(x² + 2y² + 2xy)(x² + 2y² - 2xy)

Step-by-step explanation:

<h3>Given binomial:</h3>

x⁴ + 4y⁴

In order to factorize it, follow the steps:

<h3>Complete the square:</h3>

x⁴ + 4y⁴ =
(x²)² + 2*(x²)*(2y²) + (2y²)² - 2*(x²)*(2y²) =
(x² + 2y²)² - (2xy)² =
(x² + 2y² + 2xy)(x² + 2y² - 2xy)

Used identities:

(a + b)² = a² + 2ab + b²
a² - b² = (a + b)(a - b)
