Mnenie [13.5K]3 years ago
6 0

Step-by-step explanation:

3x + 2y = 4

2y = -3x +4

y = -3/2x +2

6x+4y = 8

4y = -6x +8

y = -6/4x + 8

y = -3/2x + 8

same slope, bit different intercepts. they are parallel. no solutions

Answer:

Infinite solutions

Step-by-step explanation:

1) First, you can solve this easily by elimination. Multiply the first equation by -2 in order to cancel out terms when adding to the second equation.

2) Then, add the new set of equations together. However, everything cancels out, bringing us to 0 = 0. This means that the lines the equations make must be the same. Thus, all real numbers must make this equation true, meaning that there are infinite solutions.

If a_1=2a 1 ​ =2 and a_n=(a_{n-1})^2-2a n ​ =(a n−1 ​ ) 2 −2 then find the value of a_4a 4 ​ .

Answer:

  2

Step-by-step explanation:

We assume your recursive formula is ...

  a_1=2\\a_n=a_{n-1}^2-2

Using this to find a4, we get ...

  a_2=a_1^2-2=2^2-2=2\\a_3=a_2^2-2=2^2-2=2\\a_4=a_3^2-2=2^2-2=2\\\\\boxed{a_4=2}

Help plsss thank youuuu

<u>Answer:</u>

A. (x+5)

<u>Step-by-step explanation:</u>

We are given a quadratic expression x^2+8x+15 which we will factorize to see which of the given options is a binomial factor of it.

x^2+8x+15

Finding the factors of 15 such that when added, they give a result of 8.

x^2+3x+5x+15\\\\x(x+3)+5(x+3)\\\\(x+3)(x+5)

Therefore, we can see that (x+5) is that binomial factor that is present in the given options so option A. (x+5) is the correct answer.
