Hello : the system is :
<span> y= -2x+4 ...(1)
y= x² +4x+13....(2)
x²+4x+13 = -2x+4
x²+6x+9=0
(x+3)² =0
x+3=0
x= -3
subsct in (1) : y=-2(-3)+4 =10</span>
Hi miss you did not mark you thank you for asking me thank
I would multiply 60 by 3, since its 300+%
60 x 3 = 180
From there I would then add at least half of 60, which is 30
180 + 30 = 210
Since it is 380, I would just add another 20 to the equation to get around :
210 + 20 = 230
This should be a good enough estimate that is close to 380% of 60 <span />
