Use substitution method & show your work. y = x^2 + 3x - 1 4x + 1 = y

irina1246 [14]

4x + 1 = x^2 + 3x - 1
4x = x^2 + 3x - 2
0 = x^2 -x - 2
0 = x^2 -x + 1 - 3
0 = (x - 1)^2 - 3
3 = (x - 1)^2
sqrt 3=(x-1) and (-(x-1))
x = 1+sqrt 3 and 1-sqrt 3
sqrt means square root

Answer:

- 1.568

Step-by-step explanation:

Let's assume that the base of the given logarithm is 10.

log m = 0.345 ⇒ $10^{0.345}$ = m

log n = 1.223 ⇒ $10^{1.223}$ = n

mn = $10^{0.345}$ × $10^{1.223}$ = $10^{1.568}$

$\frac{1}{mn}$ = $10^{-1.568}$

log $10^{-1.568}$ = - 1.568 × log 10 = - 1.568
