Answer:
pretty sure its -2,3 :)
Step-by-step explanation:
Okay so for this one, we have to isolate our X.Lets start by moving the negative 5 on the other side of the equal sign. Remember to not mix a number that is with an X with a normal number (in this case it would be the -3x and the -5). So in putting our -5 on the other sign it becomes positive. Here’s what we have: x^2-3x=5. x^2 is the same thing as 2x.So now you have to minus 3x off of your 2x. This gives us -1x, but can just be put as -x. So now we have -x=5. You’re answer could either be 5 or -5 if you decided to divide it by -1 seeing as your -x is technically -1.
<span>for y varies directly with x, you should have
y=kx
where k is constant of variation.ok</span>
F(x)=x^2+3x-7, x=3
f(3)=3^2+3(3)-7
f(3)=9+9-7
f(3)=11
Answer:
1.50 Belts must not be produced.
3.00 Wallets should be produced.
Step-by-step explanation:
To solve this linear programming problem, we can use Solver in Excel, as shown in the attached file.
Two decision variables are created: Belts and Wallets.
There are two restrictions regarding the cutting and sewing required for each type of Product.
The optimal solution is:
The maximum optimal profit is $63.00
1.50 Belts must not be produced.
3.00 Wallets should be produced.
