Answer:

Ming has to play for 15 hours to earn 500 points.

Step-by-step explanation:

1. Make an equation: 200 + 20h = 500 pts

2. 500 - 200 = 300

3. 300 / 20 = 15

h = 15 hours

First, substract the total of points with the points he got from signing up, to find the points he got after playing
points after playing = 500 - 200
points after playing = 300

Second, divide the points after playing by the number of points per hour, to find how long Ming played
time = 300/20
time = 15

Ming played for 15 hours

Evgen [1.6K]

we have that

f(x) = -x^{2} - 4x+ 2

using a graph tool

see the attached figure

statements

case a) The domain is {x|x ≤ –2}-------> Is False

the domain is all real numbers---------> the interval (-∞,∞)

case b) The range is {y|y ≤ 6}.------> Is True

The range is the interval (-∞,6]

case c) The function is increasing over the interval (–∞ , –2).-----> Is True

See the attached figure

case d)The function is decreasing over the interval (−4, ∞).-----> Is False

In the interval (-4,-2) the function is increasing and in the interval (-2,∞) the function is decreasing (See the attached figure)

case e)The function has a positive y-intercept.------> Is True

The value of y-intercept is 2
