P = R - C

R - C = P

- C = P - R

Multiply both sides by - 1

-C*-1 = -1*(P - R)

C = -P + R

C = R - P

answer choice a

x^2 - 5x - 1 = 0

a=1, b=-5, and c=-1

next you plug in the numbers into the quadratic formula

-(-5) plus or minus the square root of (-5)^2 - 4(1)(-1)/ 2(1)

after you simply, you should get 5 plus or minus the square root of 29, which is answer choice a

A = x² + xy +2y-1<br>A+B= 2x² - xy - 4y-1<br>a) find A-B<br>b) if (A-B) = X<br>find y

Alinara [238K]

Answer:

see explanation

Step-by-step explanation:

Given the 2 equations

A = x² + xy + 2y - 1 → (1)

A + B = 2x² - xy - 4y - 1 → (2)

From (2)

B = 2x² - xy - 4y - 1 - A

= 2x² - xy - 4y - 1 - (x² + xy + 2y - 1) ← distribute parenthesis

= 2x² - xy - 4y - 1 - x² - xy - 2y + 1 ← collect like terms

= x² - 2xy - 6y

Hence

A - B = x² + xy + 2y - 1 - (x² - 2xy - 6y) ← distribute parenthesis

= x² + xy + 2y - 1 - x² + 2xy + 6y ← collect like terms

= 3xy + 8y - 1

(b)

Given A - B = x, then

x = 3xy + 8y - 1 ( add 1 to both sides )

x + 1 = 3xy + 8y ← factor out y from each term

x + 1 = y(3x + 8) ← divide both sides by (3x + 8)

y = $\frac{x+1}{3x+8}$
