2|2x − 2| + 4 = 20.
2|2x − 2|  = 20.- 4
2|2x − 2| = 16
|2x − 2| =8

That means:
1st: 2x-2 = 8   and 2nd: 2x - 2 = -8
1st: 2x=10 and x = 5

2nd  2x-2=-8, 2x = -6 and x = -3

So x = 5 and x = -3 (1st answer)

Help quick Given f(x) and g(x) = k⋅f(x), use the graph to determine the value of k.
Salsk061 [2.6K]

Answer:

k = -3

Step-by-step explanation:

F(x) has a positive slope

g(x) has a negative slope

Let x = -3

The y value goes from 1 to -3

g(x) = k⋅f(x)

-3 = k(1)

-3 = k

Harold, a marina manager, purchased two boats. He then sold the boats, the first
zaharov [31]

Harold paid $ 16,632 and $ 38,808 for each of the boats.

Since Harold, a marina manager, purchased two boats, and he then sold the boats, the first at a profit of 40% and the second at a profit of 60%, and the total profit on the sale of the two boats was 54 % and $ 88 704 was the total selling price of the two boat, to determine what did Harold originally pay for each of the two boats the following calculation must be performed:

  • 55 x 0.6 + 45 x 0.4 = 51
  • 65 x 0.6 + 35 x 0.4 = 53
  • 70 x 0.6 + 35 x 0.4 = 54

  • 88,704 x 0.7 = 62,092.80
  • 160 = 62,092.80
  • 100 = X
  • 100 x 62,092.80 / 160 = X
  • 38.808 = X

  • 88,704 x 0.3 = 26,611.20
  • 140 = 26,611.20
  • 100 = X
  • 100 x 26,611.20 / 160 = X
  • 16,632 = X

Therefore, Harold paid $ 16,632 and $ 38,808 for each of the boats.

Solve for p.
KonstantinChe [14]

Hi,

Answer: All Real Numbers

This can be achieved in 7 easy steps!

<u>My Numerical work:</u>

1. 2p + 3 > 2(p - 3)

Simplify both sides of the inequality:

2. 2p + 3 > 2p - 6

Subtract 2p from both sides:

3. 20 +3 - 20> 2p - 6 - 2p

4. 3 > -6

Subtract 3 from both sides:

5. 3 -3 > -6 - 2p

6. 0 > -9

7. All real numbers are solutions.

I Hope I Helped!

Answer:

C

Step-by-step explanation:

4xy(y^2 + 2x)               Remove the brackets (distributive law)

4xy^3 + 8x^2y

You have to turn the two terms around to see the correct answer. That's perfectly alright when dealing with addition of pluses.

8x^2y + 4xy^3
