Answer:

option C (3 - x)(x + 3)

Step-by-step explanation:

[(9 - x²) / 3x] / [(x² + 6x + 9) / 3x]

multiply by 3x/3x = 1

(9 - x²) / (x² + 6x + 9)

factoring

(3 - x)(3 + x) / (x + 3)(x + 3)

(x + 3) is common

(3 - x) / (x + 3)

Easiest way is if you substitute each point (x,y) into each set of equations and both points work for both equations in the system of equations, then it is the correct answer

Otherwise substitute one equation for y in the other equation:
2x + 6 = x^2 + 5x + 6
-2x - 6. -2x -6
0 = x^2 + 3x. Factor
0 = x (x + 3)
Solve: x = 0. x + 3 = 0. ——> x = -3. Substitute into one original equation to get y value for
y = 2x + 6.
y = 2(0) + 6. y = 2(-3) + 6
y = 6. y = -6 + 6 —-> y = 0
(0 , 6) And. (-3 , 0)

How do I solve 1/2z=9 1/4?
Nastasia [14]

Answer:

z = 9/2

Step-by-step explanation:

1/2z = 9 1/4?

z = 9/2

Explanation:

Simplify

9 x 1/4 → 9/4

Multiply 2 to both sides to cancel out the 2

1z = 9/4

Note: 1z is just z
