Answer and working out are linked below, hope it helps //// y = 31, x = 8
Answer:
x = 1 ,or x = -7
Obviously, the true answer is not in the options given.
Step-by-step explanation:
x² + 6x - 6 = 10
The above equation can not be factorized, hence the use of Almighty Formula.
x = [-b +- √b² - 4ac] / 2a
Where a = 1, b = 6, c = -6
x = [-6 +- √6² - (4*1*-6)] / 2*1
x = [-6 +- √36 - (-24)] / 2
x = [-6 +- √36 + 24] / 2
x = [-6 +- √60] / 2
x = [-6 +- 7.75] / 2
x = [-6 + 7.75] / 2 ,or x = [-6 - 7.75] / 2
x = 1.75/2 ,or x = -13.75/2
x = 0.875 ,or x = -6.875
Approximately
x = 1 ,or x = -7
Answer:
the line of symmetry. It's like a mirror.
Step-by-step explanation:
Answer:
P(0) = 2000
P(10) = 2414
Step-by-step explanation:
The price for today is given by P(t) when t=0. Put 0 where t is, and do the arithmetic.
P(0) = 2000·1.019^0 = 2000
The price in 10 years is given by P(t) when t=10. Put 10 where t is, and do the arithmetic.
P(10) = 2000·1.019^10 ≈ 2000·1.207096 ≈ 2414
