Answer:
x=-1, y=2
Step-by-step explanation:
Given:
2y=6x+10
y=2x+4
Substitution for y into first equation:
2(2x+4)=6x+10
4x+8=6x+10
0=2x+2
2x=-2
x=-1
y=2(-1)+4
y=2
1. The answer is 1. To get this answer, substitute x=3 into the function and solve for f(x)
2. The answer is 12. Substitute -5 in place for f(x) and isolate and solve for x.

Let x be the required waranty period, then
P(X < x) = P(z < (x - 12)/(8/12)) = 1 - 0.067 = 0.933
P(z < 12(x - 12)/8) = P(z < 1.498)
12(x - 12)/8 = 1.498
x - 12 = 8(1.498) / 12 = 0.9987
x = 12 - 0.9987 = 11
Therefore, they should waranty for 11 years so that no more than 6.7% fail within that time.
cost of production = %13
Let the price be p, then
revenue less price of failed iron = p - 0.067(13) = p - 0.871
Profit = p - 0.871 - 13 = 5
p - 13.871 = 5
p = 5 + 13.871 = 18.871
Therefore, the should charge $18.87 per waffle iron.
