8 0

Answer:

x = 2, x = -6

Step-by-step explanation:

$x^2+4x-4=8$

Subtract 8 from both sides.

$x^2+4x-4-8=8-8$

Simplify.

$x^2+4x-12=0$

Solve with quadratic formula.

a = 1

b = 4

c = -12

I do not have time to show work for quadratic formula parts.

I am so sorry for this inconvenience.

Answer:

Part A:

Median value for Brand X = 13

Median value for Brand Y = 16

Part B: Brand Y has a longer battery life

Step-by-step explanation:

Part A:

Median value is depicted on a box plot by the vertical line that divides the rectangular box. Therefore:

Median value for Brand X = 13

Median value for Brand Y = 16

Part B:

Brand Y has a higher median value (16) than Brand X (13).

This implies that brand Y has a battery life that last longer than brand X.

9. Write an equation for the line that is parallel to the given line and that passes through the given point.

timurjin [86]

Answer:

y -11 = 2(x -3)

Step-by-step explanation:

The slope of the given line is the x-coefficient: 2. The parallel line will have the same slope.

When you know the slope and a point on the line, it is convenient to use the point-slope form of the equation of a line:

y -k = m(x -h) . . . . . . line with slope m through point (h, k)

Your line's equation is ...

y -11 = 2(x -3)
