A solid dot on the graph of an inequality indicates that the number is contained within the inequality, so yo should use
or
to represent that situation, whereas a white dot indicates that the number is not contained within the inequality.
Our graph is telling us that
is greater or equal than -1, and also
is less than 3. So our inequality will be:
Total number of possible outcomes = 36
Total number of outcomes with sum 9 = 4
{3, 6} (4, 5) {5, 4} (6, 3}
P(Sum = 9) = 4/36 = 1/9
Answer: 1/9
Answer:
$5
Step-by-step explanation:
Adding the total of how much money the items are and how much she has currently is $36 and $31.
$36 - $31 = $5
Answer:
A.) y=3x-1
Step-by-step explanation:
Point-slope form can be shown using the equation: y = mx+b
In this case, m is slope, and b is the y-intercept.
Slope in this graph can be found by finding the rise over the run, or the number of blocks the line moves vertically over the number of blocks the line moves horizontally. The line moves at a rate of 3 blocks up for every 1 block to the right, or 3/1. That means that the slope is 3.
The y-intercept is wherever the line crosses the y-intercept, or wherever x equals 0. This happens at y = -1.
If you plug the slope (3) and the y-intercept (-1) into the equation y = mx+b, you get y = 3x-1.
