Answer:
y ≥ x - 1
Step-by-step explanation:
First, determine the slope of the line. We can see that the slope is , because the slope has less than 1 y interval per every x interval. This means that the line is less steep. There are only 2 slope choices, , -, and 3. We can tell that the slope is positive, but it must be because it is clearly less steep than a 3 slope line.
Now, look at the portion that is shaded. It is above the line, and this means that y is greater than the equation given. We can tell it is greater than or equal to, because the line that represents the equation is shaded as well. If it was only greater than and not equal to, the line would not be shaded.
Hope this helps ! :) Please feel free to ask me any questions!
Answer:
4) is a function 5) is not a function
Step-by-step explanation:
4) This is a function because even tho some numbers in the domain have the same y value that doesnt mean the x values overlap. THink of it graphically or draw points do the points overlap? It shouldn't unlike question 5!
5) This is NOT a function. Why??? This is because now all numbers except 4 have more than one y value for one x value
for example: 1 has -1 and 3
That would overlap!!
Answer: 92.5
Step-by-step explanation:
96 93 93 92 91 84 are your highs and to find the mean you cross one on each side until there is only one or 2 left.
you are left with 93 and 92 so you add them together and divide by two to get 92.5 which is your answer

Answer:</h3><h2> -3x + y = 12</h2><h2> -2x + 4y = 18 </h2>
Step-by-step explanation:
first equation of new system would be the same as first one given:
<u>-3x + y = 12</u>
<u />
-3x+y + x+3y = -3x + x + y + 3y = -2x + 4y
12 + 6 = 18
so the second equation would be: <u>-2x + 4y = 18</u>
