Multiply the fraction by both things in the parenthesis.
Answer:
Step-by-step explanation:
The given equation is 
.
We take logarithm of both sides to base 2 to get:
Apply the power rule of logarithms to get:
We now apply the change of base formula:
To the nearest thousandth,
54.25
(0.65)(45)
=29.25
29.25+45
=$54.25
Answer:
(-3, -1); x = -3; y = -1
Step-by-step explanation:
-3x + 5y = 4; x + y = -4
solving via substitution
rearrange second equation: y = -x - 4
-3x + 5(-x - 4) = 4
-3x - 5x - 20 = 4
-8x -20 = 4
-8x = 24
x = -3
- 3 + y = -4
y = -1
(-3, -1)
Check
- 3 + -1 = -4
The slope of the line = 50
