So, hmmm keeping in mind that, an absolute value expression is in effect a piece-wise function, let's find its "slopes", the negarive slope on the left-side and the positive slope on the right side, and let's use the vertex point as our first point
what is the slope of a line that passes through (2, -1) and (0,7)
now, what is the slope of a line that passes through (2, -1) and (4,7)
since an absolute value expression is just a piece-wise with a +/- versions, then we can just combine those two.
Answer:
800 mL
Step-by-step explanation:
Let b represent the amount of solution B added to 2400 mL of solution A. The total amount of alcohol (mL) in the mixture is ...
10%×2400 + 50%×b = 20%×(2400 +b)
multiplying by 100 to get rid of the % signs and simplifying, we have ...
24000 +50b = 48000 +20b
30b = 24000 . . . . . . . . . subtract 24000+20b
b = 800 . . . . . . . . . . . . . . divide by 30
Debra added 800 mL of 50% alcohol to her 2400 mL of 10% alcohol to make a 20% solution.

Answer:
y= -1/6x
Step-by-step explanation:
Slope Intercept Formula
y=mx+b
-2= -1/6(12) +b
-2= -2+b
b= 0
y= -1/6x
Answer:
The double of 200 is 400
Step-by-step explanation:
200 x 2 = 400 or 200 + 200= 400
