Solve by completing the square

x^2-6x-16=0

Answers

Answer 1

Answer:

Answer:

x = 8 or

x = -2

Step-by-step explanation:

Completing The Square:

x² - 6x - 16 = 0

Here,

a = 1

b = -6

c = -16

Now,

x² - 6x + [6/2(1)]² - [6/2(1)]² - 16 = 0

x² - 6x + (6/2)² - (6/2)² - 16 = 0

x² - 6x + (3)² - (3)² - 16 = 0

(x - 3)² - 9 - 16 = 0

(x - 3)² - 25 = 0

(x - 3)² = 25

x - 3 = +-√25

x - 3 = +- 5

x = 3 +- 5

x = 3 + 5 or x = 3 - 5

x = 8 or x = -2

Step-by-step explanation:

y = x+.6

Solve for x

Subtract .6 from each side

y-.6 = x+.6 -.6

y-.6 =x

Let y = 3 y-.6 = 3-.6 = 2.4 =x x=2.4

Let y=4.2 y-.6 = 4.2 - .6 = 3.6 =x x=3.6

Let y =2 y-.6 = 2-.6 =1.4 =x x=1.4

Explain how finding 4x384 can help you find 4x5384

Answers

Using the distribution property of multiplication which states that a(b + c) = a x b + a x c. Hence, 4 x 5384 = 4(5000 + 384) = 4 x 5000 + 4 x 384 = 20,000 + 4 x 384. Therefore, finding the value of 4 x 384 will help you to find the value of 4 x 5384 because, adding the value of 4 x 384 to 20,000 gives you the value of 4 x 5384.Hope this helps.

Delivery schedule: 50 frames per working day (90 days in the quarter). Iron Horse Frames Inc.: $300 per frame. Delivery schedule: 4,500 (50 frames x 90 days) frames at the beginning of July to last for three months. Hogg accepted Iron Horse Frames Inc.'s bid because it was the low-cost bid. Required: 1.
