Answer:
x = 38
Step-by-step explanation:
using the law of logarithms
• x = n ⇔ x =
, hence
(2x - 12) = 3 ⇒ 2x - 12 =
= 64
add 12 to both sides
2x = 76 ( divide both sides by 2 )
x = 38
Answer:
y = x +
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m =
with (x₁, y₁ ) = (- 2, 1 ) and (x₂, y₂ ) = (6, 3 )
m = =
=
=
, then
y = x + c ← is the partial equation
to find c substitute either of the 2 points into the partial equation
using (6, 3 ) , then
3 = + c ⇒ c = 3 -
=
y = x +
← equation of line
