Answer:
b=41
Step-by-step explanation:
180=19v-41+(180-(20v+39))+17v
v=5
180=19v-41+b+17v
180=19(5)-41+b+17(5)
b=41
Lemme give you a cheap answer, by simply using the "compound interest formula", which is what that is, 2% compounded yearly
thus

plug in those values, and simplify
.10x + .05y = 4.50
x + y = 30
Is the formula
1/4 of 180 gets you the answer 45
X- intercept= (3, 0), (-2, 0), (2,0)
y= (0, 12)
5. g(x)=(x-3)(x+2)(x-2)
