Answer:
The answer is B.
Step-by-step explanation:
In a linear pair, the total angles is 180°. So we can form an expression for both angles. Let x be the smaller angle and 8x be the larger angle :
x + 8x = 180°
9x = 180°
x = 180° ÷ 9
x = 20°
Next, we have to substitute the x value into the larger angle expression :
8x = 8 × 20° = 160°
Answer:
x = -3.5
Step-by-step explanation:
First we create the equation.
Let x = the unknown number
7x-1 = 5x - 8
Add 8 to both sides
7x + 7 = 5x
Subtract 7x
7 = -2x
Divide by 2
-7/2 = x
-3.5 = x
Answer: 115 = 2.00713
Step-by-step explanation:
Formula
115° × π/180 = 2.007rad
Answer:
Option 3:
Step-by-step explanation:
Logarithmic functions represented by means that where x > 0, <em>b </em>> 0, and <em>b</em> ≠ 1.
According to the quotient rule:
In the given problem, since both logs have the same base = 4, then we can model to the quotient rule, resulting in:
Quotient rule:
Therefore, the correct answer is Option 3:
