Answer: choice A

Step-by-step explanation:

Based on the pythagorean theorem which states

a^{2} +b^{2} =c^{2}

Solve this system of linear equations. Separate
Arte-miy333 [17]

Answer:

x = -7, y = -1

Step-by-step explanation:

Solve the following system:

{3 y - 2 x = 11 | (equation 1)

2 y + 3 x = -23 | (equation 2)

Swap equation 1 with equation 2:

{3 x + 2 y = -23 | (equation 1)

-(2 x) + 3 y = 11 | (equation 2)

Add 2/3 × (equation 1) to equation 2:

{3 x + 2 y = -23 | (equation 1)

0 x+(13 y)/3 = -13/3 | (equation 2)

Multiply equation 2 by 3/13:

{3 x + 2 y = -23 | (equation 1)

0 x+y = -1 | (equation 2)

Subtract 2 × (equation 2) from equation 1:

{3 x+0 y = -21 | (equation 1)

0 x+y = -1 | (equation 2)

Divide equation 1 by 3:

{x+0 y = -7 | (equation 1)

0 x+y = -1 | (equation 2)

Collect results:

Answer: x = -7, y = -1

George has opened a new store and he is monitoring its success closely.
Nataly_w [17]
(r-c)(3) means that you will simply plug in the value 3 as x in the functions r(x) and c(x) and take the difference of both.

Solving for the value of the functions we'll get:
r(3)= (3)^{2}+5(3)+14=9+15+14=38
c(3)= (3)^{2}-3(3)+14=9-9+4=4
(r-c)(3)=38-4=34

Since the value is positive, we can say that the store will profit in its third month. Knowing that r(x) and c(x) is measured in hundreds of dollars, we can also say that the profit will be $3400.

ANSWER: C. The new store will have a profit of $3400 after its third month in business.
