|x+6| =8 <br> A) x=-2 and x= -14<br> B) x= -2 and x= 14 <br> C) x=2 and x= -14 <br> D) x=2 and x= -2
erica [24]

Answer:

C) x=2 and x= -14

Step-by-step explanation:

|x + 6| = 8

means

x + 6 = 8 or x + 6 = -8

x + 6 = 8

x = 2

x + 6 = -8

x = -14

At a basketball game, an air cannon launches T-shirts into the crowd. The function y=−1/8x^2 + 4x represents the path of a T-shi
Juliette [100K]

Answer:

The T-shirt lands in the bleachers at a height of 14 feet.

Step-by-step explanation:

The point where they meet is the solution of the simultaneous system of equations:

y = -\frac{1}{8}x^2+4x...........................................(1)

3y = 2x - 14..............................................(2)

From (2),

y = \frac{2}{3}x-\frac{14}{3}.................................................(3)

Substituting (3) in (1),

\frac{2}{3}x-\frac{14}{3} =  -\frac{1}{8}x^2+4x

Multiply through by 24 (the LCM of 3 and 8, the denominators of the fractions)

(24\times\frac{2}{3}x)-(24\times\frac{14}{3}) =  (-24\times \frac{1}{8}x^2)+(24\times4x)

16x - 112 = -3x^2+96x

3x^2-80x -112 = 0

(x-28)(3x+4) = 0

x-28 = 0                 OR        3x+4=0

x=28                       OR        x = -\frac{4}{3}

The value of <em>y</em> represents the height.

Substituting for <em>x</em> in (3)

y = \frac{2}{3}\times28-\frac{14}{3} = \frac{56}{3} - \frac{14}{3} = 14

y = \frac{2}{3}\times(-\frac{4}{3})-\frac{14}{3} = -\frac{8}{9} - \frac{14}{3} = -\frac{50}{9}

We discard the negative answer.

Hence, the T-shirt lands in the bleachers at a height of 14 feet.

Where does the graph of x2 - x - 2 = y cross the x-axis?
garik1379 [7]
It crosses the x axis when y = 0.
so we need to solve x^2 - x - 2 = 0.
This is done as follows:
x^2-x-2=0
(x-2)(x+1) = 0
Therefore x = 2 or x = -1.

So the two coordinates are (2,0) and (-1,0) the answer is A
