Slope = (-2 + 4)/(-2-2) = 2/-4 = -1/2
y = mx + b
so
b = y - mx
b = -2 -(-1/2)(-2)
b = -2 - 1
b = - 3
equation
y = -1/2x - 3
answer is B.
y = -1/2x - 3
After you realize that
0.00025 = 2.5·10^-4
= 250·10^-6 or 250 μ
= 250,000·10^-9 or 250,000 n
then it becomes a matter of semantics. Both A and D are correct representations, so choice B is incorrect.
Choice C present a dilemma. If you say it is correct, then there are 3 correct choices (A, C, D), not two, so C is incorrect.
If you say it is incorrect, then there are two correct answers (A, D), making choice C correct.
I'd probably choose C and try to avoid the argument with my teacher.
Answer:
B and D.
Step-by-step explanation:
B. The numerator = 2*1 = 2 and x^4 - y^4 = (x^2 - y^2)(x^2 + y^2).
D . (x^2)^2 - (y^2)^2 = x^4 - y^4.
From Pythagoras --> 10^2 + 12^2 = 244
from corner to corner it is root244 or about 15.6 feet
Answer:
10 millimeters
Step-by-step explanation:
Radius is just a half of the diameter
