Answer:
Step-by-step explanation:
because the two lines are not unique.. in other words they lay on top of each other.. they have many solutions and we can't determine price .. so answer C
Answer:
b= -1/5
Step-by-step explanation:
Though a variable's sign changes when it is multiplied by -1, its absolute value does not. Therefore, we can eliminate the 1:
1/5+b=0
b+1-1/5=0-1/5
b+0/5= 0 -1/5
b=0 -1/5
and you have b= -1/5 as your answer
<u>The reflection of any point across the x-axis</u>:
⇒ means that x-coordinate remains the same
⇒ <em>but</em> the y-coordinate is <em>multiplied by '-1'</em>
<em />
<u>In this case</u>:
⇒ (50,25) <em>becomes</em> (50,-25)
<u>Answer: (50,-25)</u>
<u></u>

Y = t*e^(-t/2)
y' = t' [e^(-t/2)] + t [e^(-t/2)]' = e^(-t/2) + t[e^(-t/2)][-1/2]=
y' = [e^(-t/2)] [1 - t/2] = (1/2)[e^(-t/2)] [2 - t] = - (1/2) [e^-t/2)] [t -2]
