What is the degree of the function w(x) = (x-2)(x+3)
WITCHER [35]

Answer:

the degree is 2

Step-by-step explanation:

because when you distribute x - 2 to x+3 = x^2 - x - 6. When you see an exponent in a trinomial that's the degree. If it's polynomial and has multiple exponents the degree is the highest number of the exponents.

Example:

2x^5 + x^3 - 4x + 1

The degree of this polynomial is 5 since it's the highest exponent number.

Can you please solve number 49? thank you in advance
Ivanshal [37]

Answer:

Option (c) is correct.

Step-by-step explanation:

See the attached figure.

Here, x + y = 10 cm. ............ (1)

The height h divides the whole right triangle into two different right triangles.

If we consider the height as h, then applying Pythagoras Theorem,  

h² = 6² - x² {From small triangle} ........... (2)

Again, from large triangle we can write,

h² = 8² - y² .............. (3)

Now, from equation (2) and (3) we can write  

6² - x² = 8² - y²

⇒ 36 - x² = 64 - (10 - x)² {From equation (1)}

⇒ 36 - x² = 64 - 100 - x² + 20x

⇒20x = 72

⇒ x = 3.6 cm.

So, from equation (1) we get, y = 10 - 3.6 = 6.4 cm.  

Therefore, option (c) is correct. (Answer)

3x + 4y = 8<br> How do I solve this
dimaraw [331]

Answer:

y= (-3x+8)/4

x = (-4 +8)/3

Step-by-step explanation:

3x + 4y = 8

-3x               -3x

4y = -3x +8     divide ALL by 4

y= (-3x+8)/4

3x + 4y = 8

    -4y          -4y

3x = -4 +8     divide ALL by 3

x = (-4 +8)/3
