Answer:

  82°

Step-by-step explanation:

The given angles are vertical angles, so have the same measure:

  (10x +8) = (12x -10

  18 = 2x . . . . . . . . . . add 10-10x

  9 = x

  10x +8 = 10(9) +8 = 98

So, angles 1 and 3 measure 98°. Angles 2 and 4 are the supplement of this, so ...

  ∠2 = 180° -98° = 82°

3. Given this quadratic equation, 2x2 - x - 28 = 0,
JulijaS [17]

Answer:

a) (2x+7)(x-4)

b) x = -7/2 and x = 4

Step-by-step explanation:

a) (2x  ?)(x  ?)

set up the above and considered factors of 28 that, when paired with 2, would give me -1x and -28  → (1·28, 2·14, 4·7)

after trial-and-error, found that 4 and 7 worked (used un-FOIL)

b) 2x + 7 = 0

2x = -7

x = -7/2

*********

x-4 = 0

x = 4

Find the explicit formula for the general nth term of the arithmetic sequence described below. Simplify the formula and reduce a
NemiM [27]

Answer:

an = 4/3n - 13/3.

Step-by-step explanation:

The first term is a1,

a24 = a1 + 23d

83/3 = a1 + 4/3* 23

a1 =    83/3 - 92/3

a1 = -9/3 = -3.

So the nth term an =  -3 + 4/3(n - 1)

an = -3 + 4/3 n - 4/3

an = 4/3n - 13/3
