The sum of the interior angels is 180(n-2). In this case 180(5-2)= 540. So the equation is 540=100+103+4x+(3x+3)+(5x-2). Then solve for x. X=28

Answer:

Equation: 540=(4x)+(3x+3)+100+103+(5x-2)

x=28

Step-by-step explanation:

540° in a 5 sided polygon

so knowing that

540=(4x)+(3x+3)+100+103+(5x-2)

Combine Like Terms

540=(4x+3x+5x)+(3+100+103+−2)

540=12x+204

flip equation

12x+204=540

subtract 204 from both sides

12x=336

divide both sides by 12

x=28

Question 11 of 25
malfutka [58]

Answer:

D

Step-by-step explanation:

simple : when we have a point defined as (1, 4), it means x = 1, y = 4.

and since the point is on the graph of a function/equation it means that when we use x = 1 and calculate the equation, we get 4 as result (= y). so yes, that means that both sides of the "=" sign are indeed equal for this pair of values, which makes the equation true.

but there will be usually many other pairs that do that too.

What is the equation in point-slope form for the line parallel to y=-8x - 5 that contains j(-2, 9)
Julli [10]

Answer:

y - 9 = -8(x + 2)

Step-by-step explanation:

What is the equation in point-slope form for the line parallel to y=-8x - 5 that contains j(-2, 9)

Step 1

y intercept =

y = mx + b

y=-8x - 5

m = -8, b = -5

Point slope form

y - y1 =m( x - x1)

We are given coordinates:

j(-2, 9) = (x1, y1) where ,

x1 = -2

y1 = 9

Hence, our point slope form equation is:

y - 9 = -8(x -(-2))

y - 9 = -8(x + 2)

Xy-3y(x-4z) algebraic processes
Tems11 [23]

Answer:

See explanation for answer.

Step-by-step explanation:

xy −3y(x−4z)

=xy + −3xy + 12yz

=xy + −3xy + 12yz

= (xy+−3xy) + (12yz)

=−2xy + 12yz

Answer:

= −2xy + 12yz

I'm sorry if this is incorrect.

I hope I helped!

Have a lovely day!

Side note:

I don't completely know what algebraic process is so I just solved it like I

would with a regular equation. If that's even what this is. If you have the

time then please tell me if I answered your question and if I didn't then

please tell me what I did wrong.
