What is the value of x?

Mathematics
2 answers:
stiks02 [169]2 years ago

Answer:

x = 23

Step-by-step explanation:

Seeing same-side exterior angles theoreom,

both of these angles add up to 180°.

Looking at this,

3x + (4x+19) = 180

3x + 4x + 19 = 180

Subtracting both sides by 19 to get x on the LHS:

3x + 4x + 19 - 19 = 180 - 19

7x = 161

x = 23

Plz help! what is the end of behavior of f(x)?
Tanzania [10]

Answer:

B

Step-by-step explanation:

The end behavior of a function is how the graph behaves as it approaches negative and positive infinity.

Let's take a look at each end.

As x approaches negative infinity:

As x approaches the left towards negative infinity, we can see that the graph is shooting straight upwards.

Therefore, as x\rightarrow-\infty, our function f(x) is increasing and increasing up towards positive infinity.

Therefore, the end behavior at the left will be:

\text{As } x\rightarrow-\infty, f(x)\rightarrow\infty

As x approaches (positive) infinity:

As x approaches the right towards positive infinity, we can see the that graph is also shooting straight upwards.

Therefore, the end behavior will be exactly the same. As x approaches positive infinity, f(x) <em>also</em> approaches positive infinity.

Therefore, the end behavior at the right will be:

\text{As } x\rightarrow \infty, f(x)\rightarrow \infty

Therefore, our answer is B.

What is the value of x 2.5(12.75x + 24.50)=188.75
Liono4ka [1.6K]
Divide by 2.5: 2.5(12.75x+24.50)/2.5 = 188.75/2.5 .

simplify: 12.75x + 24.50=75.5 .

subtract 24.50 from both sides

simplify: 12.75x = 51 .

x= 4.

Dj Jacqueline is making a playlist for a friend: she is trying to decide what 15 songs to play and in what order they should be
Tasya [4]

Answer:

4.4 * 10^21

Step-by-step explanation:

Given :

Number of pop, n(p) = 10

Number of reggae, n(r) = 25

Number of blues, n(b) = 10

Total number of songs to select (n) = 15

If she wants equal Number if the 3 genres

Each genre will have : 15/3 = 5 songs each

Hence,

(10C5 * 25C5 * 10C5) * n!

Combination formula :

pCr = p! / (p-r)! r!

Using calculator to save computation time :

(10C5 * 25C5 * 10C5) * n!

(252 * 53130 * 252) * 15!

= 4412050844368527360000

= 4.4 * 10^21
