How do you solve: cos(x-π/3)=-1​
gladu [14]

Answer:

x = \frac{4\pi }{3}

Step-by-step explanation:

given

cos(x - \frac{\pi }{3}) = - 1, then

x - \frac{\pi }{3} = cos^{-1}(- 1) = π

Add \frac{\pi }{3} to both sides, hence

x = π + \frac{\pi }{3} = \frac{4\pi }{3}

What algebraic expression must be added to the sum of 3x2 +4x+8 and 2x2−6x+3 to give 9x2−2x−5 as the result?
vesna_86 [32]

Answer:

4x^2-16

Step-by-step explanation:

-This is an addition/subtraction problem.

#We subtract the sum of the first two expression from the third expression:

\#Add \ first \ two\\\\=3x^2 +4x+8 +2x^2-6x+3\\\\=5x^2-2x+11\\\\\# Subtract\ from \ the \ third\\=(9x^2-2x-5)-(5x^2-2x+11)\\\\=9x^2-2x-5-5x^2+2x-11\\\\=4x^2-16

Hence, the expression 4x^2-16 must be added to the first two.
