PLLSSSS HELPPP!! 10 POINTS!!! Suppose you have a pair of supplementary angles. One angle measures (6x+28)° and the other angle m

LekaFEV [45]

Answer:

d and g

Step-by-step explanation:

Supplementary angles add up to 180 degrees, so we know that (6x+28)+(2x+8)=180. 8x+36=180, 8x=144. x=18. 6x+28=18(6)+28=136

2x+8=36+8=44

Please just (c)fog-¹

omeli [17]

f(x) = 1/(1 - x)

g(x) = (x - 1)/x

The inverse functions f ⁻¹(x) and g ⁻¹(x), if they exist, are such that

f( f ⁻¹(x) ) = x

g( g ⁻¹(x) ) = x

So we have

f( f ⁻¹(x) ) = 1/(1 - f ⁻¹(x) ) = x

Solve for f ⁻¹(x) :

1 = (1 - f ⁻¹(x) ) x

1 - f ⁻¹(x) = 1/x

f ⁻¹(x) = 1 - 1/x

f ⁻¹(x) = (x - 1)/x

and so f ⁻¹(x) = g(x).

Similarly, you can solve for g ⁻¹(x) :

g( g ⁻¹(x) ) = (g ⁻¹(x) - 1) / g ⁻¹(x) = x

1 - 1/g ⁻¹(x) = x

1/g ⁻¹(x) = 1 - x

g ⁻¹(x) = 1/(1 - x)

So we know f(x) and g(x) are inverses of one another,

f ⁻¹(x) = g(x)

g ⁻¹(x) = f(x)

Then

(a) (f o g)(x) = x

(b) (g o f ⁻¹)(x) = g(g(x)) = (g(x) - 1)/g(x) = 1 - 1/g(x) = 1 - x/(x - 1) = 1/(1 - x)

(c) (f o g ⁻¹)(x) = f(f(x)) = 1/(1 - f(x) ) = 1/(1 - 1/(1 - x)) = 1/(x/(x - 1)) = (x - 1)/x

Please find the least common denominator for 3/8 5/12

andriy [413]

Answer:

Step-by-step explanation:

Given two fractions $\frac{3}{8}$ and $\frac{5}{12}.$

Factor the denominators of both fractions:

$8=2\cdot 4=2\cdot 2\cdot 2\\ \\12=2\cdot 6=2\cdot 2\cdot 3$

You can see that two digits 2 are the same in both denominators and there are two more factors: 2 in number 8 and 3 in number 12.

Thus, the least common denominator for $\frac{3}{8}$ and $\frac{5}{12}$ is

$2\cdot 2\cdot 2\cdot 3=24$
