Step by step explanation
Answer:
b.) x = -8
Step-by-step explanation:
Solve -4*(2x + 3) = 2x + 6 - (8x + 2)
-8x + -12 = 2x + 6 - 8x - 2
-8x - 12 = -6x + 4
-12 = 8x - 6x + 4
-12 = 2x + 4
-12 - 4 = 2x
-16 = 2x
x = -8
Answer: C) 688 km
=================================================
Work Shown:
k = 1.6d
k = 1.6*430
k = 688
430 miles is roughly equivalent to 688 km.
More accurately, 430 miles = 692.01792 km, so this approximation isn't too far off.
Cos(α + β) = cosα*cosβ - sinα*sinβ
denominator remains the same for both expressions as sinα*cosβ
the simplification uses A. Quotient Identity
