Answer:

D. 1/4 and 9/36

Step-by-step explanation:

If two ratios make a proportion then it can be shown as:

a/b = c/d ⇒ ad = bc

Let's verify the answer choices with this method

A. 1/4 and 5/25

1*25 = 4*5
25 = 20, incorrect, not a proportion

B. 1/4 and 7/24

1*24 = 4*7
24 = 28, incorrect, not a proportion

C. 1/4 and 10/48

1*48 = 4*10
48 = 40, incorrect, not a proportion

D. 1/4 and 9/36

1*36 = 4*9
36 = 36, correct, this is a proportion

Angle DEF and angle FEG are supplementary. The measure of angle DEF = (9x +1) and the measure of angle FEG = (8x + 9). What is t

RUDIKE [14]

Supplementary angles are angles that are adjacent to each other and when summed to get a total of 180 degrees. In this case, DEF and FEG are supplementary. Thus the equation is 9x +1 + 8x + 9 = 180 = 17 x + 10; x then is equal to 10 so
<DEF = 9*10 +1 =91 degrees
<FEG = 8*10 + 9 = 89 degrees

How would I solve this? Please help with Algebra 2.

natulia [17]

What it's asking is to put the equation in either f(x) or g(x).
so for
(a) you would replace all x in f(x) equation with g(x) equation.
f(x) = 3x - 2
f(g(x)) = 3(5x + 4) - 2
solve from there
(b) g(x) = 5x + 4
g(f(x)) = 5(3x - 2) + 4
