Answer:

x + x + 100 = 180

2x + 100 = 180

2x = 80

x = 40

Answer:

x=40

Step-by-step explanation:

It is a straight line, and we know that angles on a straight line are supplementary, or add to 180 degrees.

So, all the angles added together must equal 180 degrees

100+x+x=180

Combine like terms

100+2x=180

Subtract 100 from both sides

2x=80

Divide by 2 on both sides

x=40

Hope this helps! :)

Answer question in image attached :) 20 points ! I think it is 2/4 just not 100% sure :/

Answer:

$\sf \dfrac{BC}{BD} = \dfrac{2}{4}$

Explanation:

BD distance is 4 units

BC distance is 2 units

so in fractions:

$\sf \dfrac{BC}{BD} = \dfrac{2}{4}$

$\sf \dfrac{BC}{BD} = \dfrac{1}{2}$

-2 squared x (-1/2) + 8 /(-2 squared)

Colt1911 [192]

It’s 0
-2 squared is 2 times (-1/2) is -2
8 / -2 squared is 2
So 2+-2 = 0

Choose the polynomial that is written in standard form. (1 point) Group of answer choices xy3 + 4x5y + 10x3 x4y2 + 4x2y + 8x −9x

Goryan [66]

Answer:

No polynomials are in standered form.

Step-by-step explanation:

Given polynmials are,

$xy^3+4x^5y+10x^3\hfill (1)$

$x^4y^2+4x^2y+8x-9x^4y^2+4x^3y^5+10x^2\hfill (2)$

$x^6y^3+4x^4y^8+x^2\hfill (3)$

To find the polynomial of two variable in standered form we have to write the sum of the degree of each exponent in descending or ascending order.

(1) $xy^3+4x^5y+10x^3$

where sum of degree of exponents are of the form,

Sum of (degree of x+ degree of y)= $(1+3)\to (5+1)\to 3=4\to 6\to 3$

which is not a descending order or ascending so it is not a standered form.

(2) $x^4y^2+4x^2y+8x-9x^4y^2+4x^3y^5+10x^2$

where sum of degree of exponents are of the form,

Sum of (degree of x+ degree of y)= $(4+2)\to (2+1)\to (1)\to (4+2)\to (3=5)\to 2=6\to 3\to 1\to 6\to 8\to 2$

which is not a descending or ascending order so it is not a standered form.

(3) $x^6y^3+4x^4y^8+x^2$

where sum of degree of exponents are of the form,

Sum of (degree of x+ degree of y)= $(6+3)\to (8+4)\to 2=9\to 12\to 2$

which is not a descending or ascending order so it is not a standered form.
