When Lauren left her house in the morning her cell phone battery was partially charged the charge remaining in Lawrence battery
balandron [24]

Answer: Intercept of the equation = (9,0)

Charge remaining in Lauren's battery is 0 after 9 hours( since Lauren left her house)

Step-by-step explanation:

Given: When t= the number of hours since Lauren left her house, the charge remaining in Lauren's battery, as a percentage, can be modeled by the equation B=63-7t .

To find the x-intercept, put B =0  (as x denoted the independent variable , here independent variable is 't')

Hence, the x-intercept of the equation = (9,0)

i.e. Charge remaining in Lauren's battery is 0 after 9 hours( since Lauren left her house)

Which number best represents the slope of the graphed line?
Bess [88]

The number that best represents the slope of the graphed line that is given is: -4.

<h3>What is the Slope of a Line?</h3>

The slope of a line is the ratio of the vertical distance to the horizontal distance across the line. It is calculated using the formula:

Slope (m) = rise/run = change in y / change in x = (y2 - y1)/(x2 - x1)

Given the two points on a coordinate plane as shown in the mage below, let:

(x1, y1) represent (0, 2)

(x2, y2) represent (0.5, 0)

Plug in the values

Slope (m) = change in y / change in x = (0 - 2) / (0.5 - 0)

Slope (m) = -2/0.5

Slope (m) = -4

Therefore, we can state that, the number that best represents the slope of the graphed line that is given is: -4.

Select the graph that would represent the best presentation of the solution set for |z| &gt; (1/2).
xenn [34]
The absolute value of x is greater than 1/2, meaning that x is either greater than 1/2 or x is less than -1/2 (in this case, even though the numbers are decreasing or getting more negative, their absolute values are greater than 1/2). this is all i can tell you because you didnt give me any graphs.
