For this, all you need to do is subtract 2m on both sides, and your answer will be: -1 = m
Answer:
Replace x with −x.
f(x) = 3(2)−x is not correct because the y-intercept is (0, 3).
the answer is B
Step-by-step explanation:
Answer: cos (25° + 10°)
Step-by-step explanation: The expression:
sin(25°) cos(10°) − cos(25°) sin(10°)
is associated to the expression for the cosine of the sum of two angles that is:
cos (α+β) = sinα *cosβ -cosα*sinβ
Hence if we do α = 25° and β = 10°
by subtitution we get:
cos (25° + 10°) = sin(25°) cos(10°) − cos(25°) sin(10°)
Missing side length: 4
a^2 + b^2 = c^2
a^2 + 3^2 = 5^2
a^2 + 9 = 25
a^2 = 16
a = 4
