Answer:
O✓ (0,-5)
Step-by-step explanation:
Identify the x-value in the ordered pair and plug it into the equation. When you simplify, if the y-value you get is the same as the y-value in the ordered pair, then that ordered pair is indeed a solution to the equation.
The smallest angle would be 19 degrees. So option D is correct.
<h3>What is the sum of the octagon?</h3>
The sum of exterior angles of the regular octagon is 360 degrees.
Given;
The angles
x + 13 + 2x - 1 + 2x + 6 + 2x + 12 + 2x - 17 + 3x - 4 + 3x - 10 + 4x = 360
19x - 1 = 360
19x = 359
x = 18.89
The smallest angle would be
2x - 17 = 2(18.89) - 17 = 19

For this problem you must do Pythagorean theorem:
In this example 10ft is c and 7ft is a (or it could be b, and you'll be solving for a instead of b. It's the same thing, since a and b are both legs)
Plug what you know into the equation:
49 +b^{2} = 100
Bring 49 to the right side by subtracting it:
b^{2} = 51
Now you still must isolate b. The opposite of squaring is taking the square root so take the square root of both sides to cancel it from the left side:
b = 7.1414
b ≈ 7 ft

Answer:
The system of the equation has no solution
Step-by-step explanation:
Step: Solvey=3x+9for y:
y=3x+9
Step: Substitute3x+9foryiny=3x−4:
y=3x−4
3x+9=3x−4
3x+9+−3x=3x−4+−3x(Add -3x to both sides)
9=−4
9+−9=−4+−9(Add -9 to both sides)
0=−13
