Answer:
pretty sure its d
Step-by-step explanation:
the quadrant one function has asymptotes at y=0 and x=0 so x and y have to stay positive
the quadrant three function has asymptotes at y=0 and x=0 so x and y have to stay negative
Answer:
42 gallons 45% antifreeze
28 gallons 95% antifreeze
Step-by-step explanation:
If x is volume of 45% antifreeze, and y is volume of 95% antifreeze, then the total volume is:
x + y = 70
And the total amount of antifreeze is:
0.45 x + 0.95 y = 0.65 (70)
Solving by substitution:
0.45 x + 0.95 (70 − x) = 0.65 (70)
0.45 x + 66.5 − 0.95 x = 45.5
21 = 0.5 x
x = 42
y = 28
lines with undefined slope are vertical
equation are in form of x constant
through the points ( 3 , -4)
the line is x=3
No if it it was 16.450 then it would be equal to 16.45
