If f(x) = x2 – 2x and g(x) = 6x + 4, for which value of x does (f + g)(x) = 0?

Hatshy [7]

Answer:

x = - 2

Step-by-step explanation:

(f + g)(x)

= f(x) + g(x)

= x² - 2x + 6x + 4

= x² + 4x + 4

Equating to zero

x² + 4x + 4 = 0

(x + 2)² = 0

x + 2 = 0

x = - 2

adult tickets at a football game cost $6 and student tickets cost $2. A total of $1776 was collected on 372 tickets. How many ad

postnew [5]

Answer:

258

Step-by-step explanation:

Set up the two equations needed (x is the adult tickets and y is the student tickets)

x+y=372

6x+2y=1776

Solve by elimination

-2(x+y=372)

=-2x-2y=-744

Cancel like figures:

-2x-2y=-744

6x+2y=1776

= 4x=1032

x=258

Find the distance between the two points rounding to the nearest tenth

mixas84 [53]

Answer:

8.54

Step-by-step explanation:

formula:

$d=\sqrt{(x2-x1)^2 + (y2-y1)^2}$

$d=\sqrt{(-4 - (-7))^2 + (0-(-8))^2}$

$d=\sqrt{3^2 + 8^2}$

$d=\sqrt{9 + 64}$

$d=\sqrt{73}$

d= 8.54
