Answer:
y=1.5x+1; x= -0.6
y= -0.25x-6; x= -24
Step-by-step explanation:
y=1.5x+1
0=1.5x+1 (To find x-intercept/xero, substitute y=0)
-1.5x=1
x= -2/3 or x= -0.6
y= -0.25x-6
0= -0.25x-6
0.25x= -6 (Move variables to the left-hand side and change its sign)
x= -24
It's not even. And every multiple if 6 is even.
P(x > 6.9) = 1 - P(x < 6.9) = 1 - P[z < (6.9 - 5.1)/0.9] = 1 - P(z < 2) = 1 - 0.97725 = 0.02275.
Therefore P(x > 6) is about 2.5%
