Answer:
Solve by substitution
[y=5/2x-4]
[y= -x+3]
Substitute y = -x +3
[-x+3=5/2x-4]
Isolate x for -x+3=5/2x-4: x=2
For y = -x+3
Substitute x = 2
y= -2+3
Simplify
y=1
The solutions to the system of equations are:
y=1 x=2
The tens place because 4 and 8, 8 is over 5 so u round up then it is 254 rounded to the tens 55
Answer:
The answer is given below
Step-by-step explanation:
The question is not complete, because the function for the profit is not given but I can show you how to calculate this.
Since Mr. Wilson has a bakery and a juice bar, his total profit earned in t months would be the sum of profit from the bakery with the profit from the juice bar within t months.
Let us assume that the profit from the bakery in t months is given by:
B(t) = 2t³
while the profit from the juice bar in t months is given by:
J(t) =
Therefore the total profit is given by:
P(t) = B(t) - J(t) =
I'm assuming you're asking about negative or positive signs here. When I factor binomials, it depends on what would make factoring simpler for me. And how you're factoring the binomial too.
More often than not, it's going to be positive. For example, 4x^2 - 2x = 0. That would factor out to be 2x(2x-1) = 0. The sign outside is going to be positive because it's simpler to solve that way. Here, x is equal to 0 and equal to 1/2. Taking out a negative in this case would complicate the solving process.
