Solve the following system of equations by the substitution method. 2x = 10y - 8 3x + 4y + 5 = 0

Natali [406]

Answer:

x = $-\frac{41}{19}$

y = $\frac{7}{19}$

Step-by-step explanation:

2x = 10y - 8

3x + 4y + 5 = 0

2x = 10y - 8

x = 5y - 4

3x + 4y + 5 = 0

3 ( 5y - 4 ) + 4y + 5 = 0

19y - 7 = 0

19y = 7

y = $\frac{7}{19}$

x = 5y - 4

x = 5 ( $\frac{7}{19}$ ) - 4

x = $-\frac{41}{19}$

Solve log_8 12 = x – 2 . Round your answer to four decimal places.

Aleksandr-060686 [28]

Step-by-step answer:

Let's attack the left side:

log_8 12 = log (base 8) 12 = log(12)/log(8) = 1.1949875 (approx.)

Next solve

log_8 12 = x-2

log(12)/log(8) = x-2

x = 2 + log(12)/log(8)

= 3.195 (to one thousandth)
