Answer:

A=8

B=6

C=14

Step-by-step explanation:

A+b+c=28

c+b=20

Substitute c+b for 20

A+20=28

A=28-20

A=8

c+a=22

Substitute a with 8

c+8=22

c=22-8

c=14

To get b, we substitute a with 8 and b with 14

A+b+c=28

8+b+14=28

22+b=28

b=28-22

b=6

faltersainse [42]

Answer:

30units,2900

Step-by-step explanation:

Given that Country Motorbikes Incorporated finds that it costs $400 to produce each motorbike, and that fixed costs are $1600 per day.

The price function is p(x) = 700 − 5x, where p is the price (in dollars) at which exactly x motorbikes will be sold.

If x units are produced and sold we have

Costs for x units = variable costs *x +Fixed costs = 400x+1600

Sales revenue = no of units sold * price = x(700-5x) = 700x-5x^2

Profit funciton = P(x) = Sales revenue - Total cost

= 700x-5x^2-400x-1600\\=300x-5x^2-1600

To get maximum profit we use derivative test I derivative =0 and II derivative =negative

P'(x) = 300-10x\\p"(x) = -10

Producing 30 units will maximize the profit.

Max profit

=P(30) = 2900

Pleaseeeee lol i don’t wanna fail
allsm [11]

Answer:

A.

Step-by-step explanation:

x^0=1 so you can cancel it out. when a number has a negavite exponent, you have to invert it. That means y^-6 goes at the denominator and becomes y^6 and z^-6 goes up to the numerator and becomes z^6.
