Answer:
slope = (-2 +3) / (12 -3)
= 1/9
Answer:
B. x=0,2
Step-by-step explanation:
(x+4) 1
-------- = -----
6x x
Using cross products
x * (x+4) = 1*6x
Distribute
x^2 +4x = 6x
Subtract 6x from each side
x^2 +4x-6x = 6x-6x
x^2 -2x = 0
Factor out an x
x (x-2) = 0
Using the zero product property
x=0 x-2 =0
x=0 x-2+2 =0+2
x =0 x=2
Answer:
151 notes
Step-by-step explanation:
$85/1=85 notes
125/5=25 notes
150/10=15 notes
420/20=21 notes
500/100=5 notes
85+25+15+21+5=151 notes total
Step-by-step explanation:
The concentration of Marcia's solution is:
1.0 kg / 3.0 L = 0.33 kg/L
The concentration of Bobby's solution is:
(2.0 lb × 1 kg / 2.2 lb) / (7.0 pints × 1 L / 2.11 pints) = 0.27 kg/L
Therefore, Marcia's solution is more concentrated.
