3(×+2)=3×-6 I got 0 is that right or wrong

Answers

Answer:

Step-by-step explanation:

3(x + 2) = 3x - 6

3x - 6 = 3x - 6

Subtract 6 from both sides of the equation. Then you will get 3x = 3x - 12. Now subtract 3x from both sides of the equation. Leaving you with 0 = -12. So I guess it’s correct?

What is an exponential function?

It is defined as the function that rapidly increases and the value of the exponential function is always positive. It denotes with exponent y = a×

where a is a constant and a>1

It is given that:

The population of a community is modeled by this exponential function, where x represents the number of years since the population started being recorded:

p(x) = 2,400(1.025)×

Plug x = 3 years in the above function.

P(3) = 2400(1.025)³

P(3) = 2400x1.0768

P(3) = 2584.53 ≈ 2584 people

Thus, the approximate population 3 years after the population started being recorded is 2584 people option (C) is correct.

8+ (2x) = 8*(x-5)

8*(x-5) applies to the distributive law : a(b-c) = ab-ac

a=8 b=x c=5

8x-8*5

8x-40

then add 8+(2x) back into the equation and you have

8+(2x) = 8x-40

subtract 8

2x=8x-48

subtract 8x

-6x=-48

divide by -6

x=8

Step-by-step explanation:

The scaled factor has to be 2 because 4*2=8. You can check 2 is the correct answer by doing 8/2, which is 4. The scaled factor has to be proportional so if one side of ABC was 2 but the same side on ABC prime or A’B’C’ was 10 it would not be proportional, not a scaled factor. Because 2*10 is 5, not 8. But it does not give any other side lengths so it is 4.

Write the equation of the line that passes through the points (-3, -3) and (8,7).
Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal
line.

Answers

Answer:

y + 3 = 10/11(x + 3)

Step-by-step explanation:

Given the points (-3, -3) and (8, 7), we can use these coordinates to solve for the slope of the line using the formula:

[tex]m = \frac{y2 - y1}{x2 - x1}[/tex]

Let (x1, y1) = (-3, -3)

(x2, y2) = (8, 7)

Substitute these values into the slope formula:

[tex]m = \frac{y2 - y1}{x2 - x1} = \frac{7 - (-3)}{8 - (-3)} = \frac{10}{11}[/tex]

Thus, slope (m) = 10/11.

Next, using the slope (m) = 10/11, and one of the given points (-3, -3), we'll substitute these values into the point-slope form:

y - y1 = m(x - x1)

Let (x1, y1) = (-3, -3)

m = 10/11

y - y1 = m(x - x1)

y - (-3) = 10/11[x - (-3)]

Simplify:

y + 3 = 10/11(x + 3) this is the point-slope form.

Belinda, a famous portrait painter, agreed to paint Harry's portrait for $5,000. She also agreed to paint the portraits of Michelle's two Welsh Corgi dogs, Baby and Bree. Michelle agreed to pay Belinda $12,000 for the portraits. Belinda charged Michelle more because dogs annoyed her. Belinda met the spoiled dogs, and they really got on her nerves. Plus, she was behind on finishing Harry's portrait. Belinda, therefore, proceeded to assign the right to receive the money for the dog portraits and the duty to paint the dog portraits to her assistant, Fred. He eagerly accepted and painted the portraits. As payment for amounts she owed him for various duties, Belinda also assigned to Fred the right to receive payment from Harry. Neither the contract Belinda had with Harry nor the contract she had with Michelle expressly prohibited assignment or delegation of contractual rights and duties. Belinda finished the portrait of Harry and called him to come and pick it up. Meanwhile, a disgruntled secretary who disliked Belinda told both Michelle and Harry about the agreements with Fred. Michelle was furious and refused to pick up the portrait or pay anyone. Harry likewise refused to pay for his portrait claiming that the right to payment could not be assigned. What would be the most likely result if Fred sues Harry for the $12,000 payment?A. Fred will lose unless Fred can prove that he was ignorant of the fact that Harry did not want the benefits assigned.B. Harry will win because the portrait was personal in nature and could not be assigned.C. Harry will win because he did not expressly agree to the assignment.D. Fred will win because the right to receive payment could be validly assigned.E. Fred will win unless Harry can prove that Fred knew that Harry did not want the benefits assigned.
