Answer: y = 3x

Step-by-step explanation:

The answer is y=3x because every month Giorgio learns a new song. so for the first month they learned 3 songs and in the second month they learn 3 more that adds up to 6 song total, so if you just times the month by 3 you will get your answer.

Factor 6p^2 +15p+9????
Ivanshal [37]
To factor the trinomial, you can use the ac method where you multiply the first and last terms together (6 and 9) and add up to 15.
In this case ac= 54
2 numbers that multiply to 54 and add up to 15 would be 6 and 9 so place these numbers where the 15 would be:
6p^{2} +9p + 6p+9
Then group terms to simplify:
(6p^{2} +9p)(6p+9)

Simplify any like terms:
3p(2p+3) 3(2p+3)
And group together again:
(3p+3)(2p+3)
You can simplify a 3 out of the first expression one more time to get:
3(p+1)(2p+3)
Which would be the factored form. I hope this helps :)

Please help with 6 and 7
Ilya [14]

Answer:

6. The number is -5

7. The two numbers are 10 and 11

Step-by-step explanation:

Question six can be re-worded to create the following expression:

-2=\frac{4x+10}{5}

Solve for x to find the number:

-2=\frac{4x+10}{5}\\-10=4x+10\\-20=4x\\\frac{-20}{4} = x\\-5 = x

Question seven can be solved by first listing the constraints (assuming x is smaller than y):

  1. x and y are less than 20
  2. x + 1 = y
  3. 3x - 8 = 2y

To get the numbers, we can create a system of linear equations. First, solve for y in each expression:

y = x+1

2y = 3x-8\\y = \frac{3}{2}x - 4

Solve for x:

x+ 1 = \frac{3}{2}x - 4\\x + 5 = \frac{3}{2}x\\5 = \frac{3}{2}x - x\\5 = \frac{1}{2}x\\10 = x

Solve for y:

y = x + 1\\y = 10 + 1\\y= 11
