Hey there!

The given points are; (1,-3) and (3,1).

Note: Use double point formula.

[tex](y - y1) = \frac{y2 - y1}{x2 - x1} (x - x1)[/tex]

~ Put all values.

[tex](y + 3) = \frac{ - 1 - 3}{3 - 1} (x - 1)[/tex]

~ Simplify it.

[tex]y + 3 = - 2x + 2[/tex]

[tex]2x + y + 1 = 0[/tex]

Therefore, the eqaution is; 2x+y+1= 0.

What is the 100th term in the sequence?

Answers

9514 1404 393

Answer:

  -190

Step-by-step explanation:

The n-th term of an arithmetic (linear) sequence is given by ...

  an = a1 +d(n -1)

where a1 is the first term (8) and d is the common difference. We note that each term is 2 less than the one before, so the common difference is -2.

  an = 8 -2(n -1)

Then the 100th term is ...

  a100 = 8 - 2(100 -1) = 8 -198 = -190

The 100th term is -190.

9x+y=2
−4x−y=−17

Answers

Answer: x = -3    y = 29

Step-by-step explanation:

9x + y = 2

-4x - y = -17

5x = -15

Divide both sides by 5

x = -3

9x + y = 2

Substitute -3 for x

9 (-3) + y = 2

-27 + y = 2

Add 27 to both sides

y = 29

If (3a + 3b + 1) (3a + 3b - 1) = 80, then what is a + b?

Answers

Answer: a + b = 3 -        maybe

Step-by-step explanation:

( 3a + 3b + 1 )( 3a + 3b - 1 ) = 80

Expand

9a² + 9ab - 3a + 9ab + 9b² - 3b + 3a + 3b - 1 = 80

Simplify

9a² + 9b² + 18ab - 1 = 80

move the 1 over

9a² + 9b² + 18ab = 81

divide by 9

a² + b² + 2ab = 9

not really sure after this part

move the 2ab over

a² + b² = 9 - 2ab

square root both sides

a + b =  

simplify

a + b = 3 -
