Answer:
B and D
Step-by-step explanation:
To determine which point is a solution, substitute the x- coordinate into the right side of the equation and if the value obtained agrees with the y- coordinate then it is a solution.
(5, 10)
y = 5² - 2(5) + 1 = 25 - 10 + 1 = 16 ≠ 10 ← not a solution
(- 1, 3)
y = (- 1)² - 2(- 1) + 1 = 1 + 2 + 1 = 3 ← This is a solution
(1, 2)
y = 1² - 2(1) + 1 = 1 - 2 + 1 = 0 ≠ 2 ← not a solution
(3, 4)
y = 3² - 2(3) + 1 = 9 - 6 + 1 = 4 ← this is a solution
Answer is J not blue because the complement (opposite of being it) is 3/4. Blue is 1/4, so not being blue is 3/4.
Hope this helps :D
Answer:
15) For a regular polygon of N sides, the measure of one interior angle is:
A = (N - 2)*180°/N
In this case, the figure has 11 sides, then we have N = 11, and the measure of each interior angle will be:
A = (11 - 2)*180°/11
A = 9*180°/11 = 147.27°
Rounding to the first decimal after the decimal point, we get:
A = 147.3°
Then the correct option is B.
16) We know that the length of all the sides of a square is the same.
In the image, we can see that the length of the right side is 4, and the length of the top side is 2x + 4
And those lengths must be the same, then we have the equation:
2x + 4 = 4
subtracting 4 in each side of the equation we get:
2x + 4 - 4 = 4 - 4
2x = 0
The only solution for this equation is x = 0.
Then the correct option is C
