Y=1/2x +5<br> Y=-3/2x-7<br> Find x and y
gayaneshka [121]
I'm going to use the substitution method. 

If y = - 3/2 - 7, then:

1/2x + 5 = - 3/2x - 7

Combine like terms: 

4/2x = - 12. Mutiply both sides by 2/4 to get x = -12 (2/4)

Simplify to get:

x = - 6.

Plug - 6 back in for x in either equation.

Y = 1/2( - 6) + 5 which becomes Y = - 3 + 5.

X = - 6, Y = 2

For this case we first write the equation of which we will use:
 I (db) = 10log (l / l)
 We substitute the value of l.
 We have then:
 l = 10 ^ 8lo
 Substituting in the given equation:
 I (db) = 10log ((10 ^ 8lo) / lo)
 Rewriting:
 I (db) = 10 * log (10 ^ 8)
 I (db) = 80
 Answer:
 I (db) = 80
