Given f(x)=3x−4 and g(x)=x2−3, find (g ∘ f)(x).
QveST [7]

Answer:

9x^2  -24x +13

Step-by-step explanation:

(g º f)(x) = g(f(x))

g(f(x)) = (3x-4)^2 - 3

(3x-4)^2 = 9x^2 - 24x + 16

g(f(x)) = 9x^2 - 24x + 16 - 3

g(f(x)) = 9x^2  -24x +13

In the figure, AOB II (parallels) CD, find the values of x and y.
Advocard [28]

Answer:

x = 5, y = 20

Step-by-step explanation:

Since AB and CD are parallel, then

∠ AOC and ∠ OCD are Alternate angles and congruent, thus

12x + 8 = 68 ( subtract 8 from both sides )

12x = 60 ( divide both sides by 12 )

x = 5

-------------------------------

∠ OCD and 5y + 12 are adjacent angles and supplementary, thus

5y + 12 + 68 = 180 , that is

5y + 80 = 180 ( subtract 80 from both sides )

5y = 100 ( divide both sides by 5 )

y = 20

Answer this question to get 20 points!!!!
Ludmilka [50]

Answer:

Blue

Step-by-step explanation:

First, we need to find the LCD (Least common denominator)

Rewriting input as fractions if necessary:

1/10, 1/4, 1/5

For the denominators (10, 4, 5) the least common multiple (LCM) is 20.

Therefore, the least common denominator (LCD) is 20.

Now, we convert:

Red Marbles: 1/10 = 2/20

Blue Marbles: 1/4 = 5/20

Yellow Marbles: 1/5 = 4/20

As we can see, blue has the most. Now we have our answer! Good luck!
