3/2x + 1/5x = 11/6x - 2/15....to get rid of fractions, multiply by common denominator, which is 30.

45x + 6x = 55x - 4
51x = 55x - 4
51x - 55x = -4
-4x = -4
x = -4/-4
x = 1

1. 30 • 3/2x + 30 x 1/5x = 30 • 11/6x - 30 • 2/15

(To simplify, multiply both sides by the least common denominator)

2. 15 • 3x + 6x = 5 • 11x - 2 • 2

(Multiply)

3. 45x + 6x = 55x - 4

(Collect Like Terms)

4. 51x = 55x - 4

(Move variable to the left side and change its sign)

5. -4x = -4

(Divide both sides of the equation by -4)

6. x = 1

Answer:

Step-by-step explanation:

3(2) + 4(-2) = -2 2(2)-4(-2) = -8

6 - 8 = -2 4 + 8 = -8

Correct Incorrect

3(6) + 4(-5) = -2 2(6) - 4(-5) = -8

18 - 20 = -2 12 + 20 = -8

Correct incorrect

3(4) + 4(4) = -2

12 + 8 = -2

incorrect

3(-2) + 4(1) =-2 2(-2) - 4(1) = -8

-6 + 4 = -2 -4 - 4 = -8

Correct Correct

Best way is process of elimination

Please help and thank you.

Answer:

zeros: x = 5, or (5, 0)

domain: x ≥ -4

Step-by-step explanation:

The zeros are the values of x where the graph crosses the x-axis. The graph crosses at x=5, so that is the zero.

___

The domain is the set of x-values for which the function is defined. There is no graph for x < -4, so the graph is only defined for x ≥ -4. The domain is x ≥ -4.

_____

The graph has the appearance of the graph of ...

$y=\sqrt{x+4}-3$
