Graph the inequality on the axes below.
1 answer:
The first step is to graph the line 2x + y = -8. To do this, we can graph the x and y-intercepts. Letting x = 0, we get y = -8, so the y-intercept is -8. Letting y = 0, we get 2x = -8, so x = -4.
Graph the line between the points (-4, 0) and (0, -8). The line should be <em>dotted</em>, because this is a strict inequality (the points on the line are not part of the solution).
The next step is to substitute a point - I like to use (0,0): when x and y are equal to zero, we have 2(0)+0>-8, which is true. Therefore, the right side of the graph (which contains the point (0,0)) should be shaded. Note: If the inequality was not true, you would want to shade the opposite side of the graph.

Answer:
okay so you would make a line straight across the middle of the spherical shape. The line that goes all the way across is the diameter. If you were to cut that line in half that would be the radius.
Step-by-step explanation:
The first circle shown in the picture provided would be an example of diameter, and the second circle would be an example of the radius. You could just make up a value, for example say the diameter is 10, the radius would be 5.
Answer:
There is a 4% probability that a customer buys three tires.
Step-by-step explanation:
We have those following percentages
60% buy four tires. This is also the probability that someone buys four tires.
22% buy two tires
14% buy fewer than two tires(one or none).
P% buy three tires
The sum of the percentages must be 100%.
So
There is a 4% probability that a customer buys three tires.
