Answer: (-2,3)
Step-by-step explanation:
-3x + 4y = 18
6x + 2y= -6 we have to eliminate one of the variables so you will have ot
2(-3x + 4y) = 18(2) multiply the first equation by 2.
-6x + 8y = 36
6x + 2y = -6 now we could eliminate the x terms by adding them and
0 + 10y= 30 remember that is a new equation.
y= 3
Now we know that the y solution is 3 so we will put it into one of the equations and solve for x.
-6x + 8(3)=36
-6x + 24
-24 -24
-6x = 12
x= -2
Answer:
that comes out as 12x + 6
Step-by-step explanation:
that's because the number before the brackets u time it by the number/s in the brackets and that gives the answer if you want a farther explanation message me
Answer:
price = $25
maximum profit is $2400
Step-by-step explanation:
Given the function modeled by the community theatre as
p(d)=−4d^2+200d−100
The maximum profit will be ,ade at dP/dd = 0
dP/dd = -8d + 200
0 = -8d + 200
8d = 200
d = 200/8
d = 25
hence he theatre will make maximum profit at a price of $25
Substitute d = 25 to get the maximum profit
p(25)=−4(25)^2+200(25)−100
p(25) = -2500+5000-100
p(25) = 2400
Hence the maximum profit is $2400
