I don’t know about this question
Answer:
You know that y must have to equal 0. x can be anything though.
Step-by-step explanation:
The x-axis is a straight line in the center of the y-axis where y = 0.
Answer:
11/40 + 1/4 + 1/20
Step-by-step explanation:
Draw a Venn diagram: (as shown)
Consumer Ed. : 22-4=18
French : 20-4=16
Neither : 80-18-16-4=42
Using probability notation where P(A) means probability of event A occurring.
P(Consumer Ed.) = 22/80
P(French) = 20/80
P(Both) = 4/80
<em>'or ' </em>in the question means you add.
=> 22/80 + 20/80 + 4/80
=> 11/40 + 1/4 + 1/20
Answer:
y ≥ -2x + 2.5
Step-by-step explanation:
It's kind of hard to tell because no points are given on the graph, but we can first find the b value of 2.5 in the equation y = mx +b as it is the y-intercept.
Using that value, we can also recognize that at one, it looks like the y-value is .5. using our slope formula (change in y / change in x), we can plug in the two points of (0, 2.5) and (1, 0.5) to get a slope of -2.
Now that we have our equation, we can make it an inequality!
Since the graph is shaded upwards, we know it is going to be a greater than symbol, and since the line itself solid and not dotted, we know that the points on the line are also solutions, meaning that it is also equal to the line
Hence, we get the ≥ sign.
Putting it all together, we get our final equation of y ≥ -2x + 2.5 ! :))
