Solve. -7x+29=6(8+3x)<br> x=
Otrada [13]

Answer:

x = -0.76

Step-by-step explanation:

-7x + 29 = 6 (8 + 3x)

-7x + 29 = 48 + 18x

-7x = 48-29 + 18x

-7x = 19 + 18x

-7x-18x = 19

-25x = 19

x = 19/-25

x = -0.76

4(2x + 3) = 5x + 3x - 6
Likurg_2 [28]

Answer:

No solution.

Step-by-step explanation:

4\left(2x+3\right)=5x+3x-6\\4\left(2x+3\right)=8x-6\\4\left(2x+3\right)\\(a=4,\:b=2x,\:c=3)\\=4\cdot \:2x+4\cdot \:3\\=8x+4\cdot \:3\\=8x+12\\8x+12=8x-6\\8x+12-12=8x-6-12\\0=-18

If the final answer is 0 and both sides of this equation are unbalanced, that means there will be no solution.

Find the concavity changes of f(x).
Give the x-coordinates.

So, the answer to the multiple choice question is -1 and 5 since those points are where f''(x) changes sign.

Note: You can tell that you're supposed to find the concavity changes of f(x) and not f''(x) because from the graph it's obvious that the concavity of f"(x) doesn't change.

Marcus randomly draws tokens from a bag containing 10 blue tokens, 8 green tokens, and 12 red tokens. The first draw is a green
IrinaVladis [17]

Answer: 1. D) 30

2. A) 8

3. B) 4/15

4. A)  2/9

5.D) 64%

Step-by-step explanation:    

1. Since, here the tokens from a bag containing 10 blue tokens, 8 green tokens, and 12 red tokens. The first draw is a green token.

Thus, the total token = 10 blue tokens+ 8 green tokens+ 12 red tokens = 30 token

Therefore, If the first draw is a green token, Then total outcomes that will possible = 30.

2. Since, getting green is an event with 8 favorable outcomes.

Therefore,  If the first draw is a green token, Then total favorable outcomes that will possible = 8.

3. The possibility of getting green in first drawn, P(G) = \frac{8_C_1}{30_C_1}

P(G) =  \frac{8}{30} = \frac{4}{15}

4. Here, Number of red socks= 5

Number of white socks = 2 and Number of  blue socks=3

Therefore total socks = 10

⇒ Probability of picking a pair of red socks,

P(R)= \frac{5_C_2}{10_C_2} = \frac{10}{45}

⇒ P(R)= 2/9

5. Since, here coin is flipped 50 times and lands on heads 32 times.

Therefore, experimental probability that coin will land on heads on the next flip = (total times in which head appears/ total number of experiments) × 100 = (32/50)×100=64%
