You are solving for p. so l=270, r= 0.03, and t= 3. l=prt so 270=p(0.03)(3).
270=p(0.09)
270/0.09=p
p=3000
Absolute value functions are v-shaped. I hthink the turning point you're referring to is the vertex. This is where the inside of the absolute value is zero.
f(x) = |x+2|
0 = x+2
-2 = x
vertex (-2,0)
1500 + 0.45x < 1.70x
1500 < 1.70x - 0.45x
1500 < 1.25x
1500/1.25 < x
1200 < x.....so she would have to sell 1201 cards to make a profit
Answer:
x = -8
Step-by-step explanation:
g(x) = 8x + 2
given: g(x) = 8x + 2 = -62
8x = -62 -2
8x = -64
x = -8
