Mathematically speaking, the linear pair postulate and linear pair theorem both express the same thing.

  • A linear pair is made up of two angles, and the sum of their measures is 180°.

<h3>What is the formula for linear pairs?</h3>
  • A two-variable linear equation of the form axe + by + c, with a, b, and c all being real numbers and not equal to zero.
  • The Transitive Property states that if all real numbers x, y, and z are equal, then x=z.
  • Substituting characteristics. If x=y, then x can be swapped to y in any equation or formula.
  • Mathematically speaking, the linear pair postulate and linear pair theorem both express the same thing.
  • A linear pair is made up of two angles, and the sum of their measures is 180°.
  • Line pairs can be congruent.
  • Adjacent angles are joined by a vertex.
  • Angles that are similar cross across.
  • A linear pairing is unnecessary.

Therefore, mathematically speaking, the linear pair postulate and linear pair theorem both express the same thing.

  • A linear pair is made up of two angles, and the sum of their measures is 180°.

Use the quadratic formula to solve the equation: 0 = x2 + x - 20
Art [367]

Answer:

(x-4)*(x+5) : x =4,-5

Step-by-step explanation:

a= 1

b= 1

c= -20

x1,2 = (-1+-(1 - (4*1*-20))^0.5)/2

x1,2 = (-1+-(1+80)^0.5)/2

x1,2 = (-1+-(81^0.5))/2

x1,2 =(-1+-9)/2

x1 = 8/2 = 4 x2 = -10/2 = -5

HELP!!!!!!!!! I’m almost done
balandron [24]

Alright, we're in the home stretch here :) All you need to remember is that i² = -1. Otherwise, it is the same as FOIL


(3-2i)(1+7i)

3-2i+21i-14i² ← Replace the i² with -1, then simplify like numbers

3+19i+14

17+19i or C

Ryan has a bank account balance of --$17.62. As soon as he realizes this, he deposits $26.50 in the account. What is Ryan's bank
Andrews [41]

The final bank balance is the sum of the initial balance and the amount of deposit made, hence amount in Ryan's account after the deposit will be $8.88

Initial bank balance = - $17.62

Amount deposited = $26.50

<u>Final balance in account will be</u> :

  • Initial balance + Amount of deposit made

  • (-17.62) + $26.50 = $8.88

Therefore, the amount in Ryan's bank account after the deposit is made will be $8.88
