R\Xb2-10r=-7 In Quadratic Equations

R²-10r=-7 in quadratic equations

 

Answer:

x= 10±√100-28 all over 2

Step-by-step explanation:

r²-10r=-7 transpose 7

r²-10r+7=0 then use the quadratic equation

x= -(-10)± √(-10)^2 -4(1)(7) all over 2(1)

simplified we have, x= 10±√100-28 all over 2

Find The Next Four Terms Of The Arithmetic Sequence 21,15,9,

Find the next four terms of the arithmetic sequence 21,15,9   Answer: The next four terms are:   3, -3, -9, -15. Step-by-step explanation: The first 3 terms of the sequence: 21, 15, 9  (decreasing sequence) a₁ = 21 a₂ = 15 a₃ = 9 Find the common difference (d): a₂ - a₁ = a₃ - a₂ 15 - 21 = 9 - 15 -6 = -6 d = -6 Find the next four terms a₄, a₅, a₆, a₇: a₄ = a₃ + d a₄ = 9 + (-6) a₄ = 3 a₅ = 3 + (-6) a₅ = -3 a₆ = -3 + (-6) a₆ = -9 a₇ = -9 + (-6) a₇ = -15 The next four terms are:  3, -3, -9, -15. The sequence: 21, 15, 9, 3, -3, -9, -15.
