You plug in numbers -3 to 3 into the x variable of the equation and then plot those points
y = -2x
X = -3 y = (-2)(-3) = 6
X = -2 y = (-2)(-2) = 4
X = -1 y = (-2)(-1) = 2
X = 0 y = (-2)(0) = 0
X = 1 y = (-2)(1) = -2
X = 2 y =(-2)(2) = -4
X = 3 y = (-2)(3) = -6
In case that looks a little cluttered here are the points to graph:
(-3, 6) (-2, 4) (-1, 2) (0, 0) (1, -2) (2, -4) (3, -6)
Answer:
27 degrees
Step-by-step explanation:
We are given that Angle AEF is 63. We can also see that EAF is a right angle. Since angles in a triangle add up to 180, we can use this to solve for AFE:
Angle AEF + EAF + AFE = 180
63 + 90 + AFE = 180
153 + AFE = 180
AFE = 27
<em>Or we can solve it another way</em>
Since EAF is a right angle, the other angles are complementary (they add up to 90) so...
Angle AEF + AFE = 90
63 + AFE = 90
AFE = 27
Answer:
The answer is option A
Step-by-step explanation:
Reflection in the y axis is
(x , y) → ( - x , y)
The coordinates of A are ( 2, -5)
When it's reflected in the y axis it becomes
( - 2 , - 5)

Answer:
I would probably choose warlock if my computer could handle it ;w;
The relationship between variance and standard deviation is :
Standard deviation = sqrt (variance),
Variance = standard deviation^2.
