Answer: concave
Step-by-step explanation:
THE EQUATION TO THIS PROBLEM IS y=2x+12
For questions #6 & #8, you didn't complete them or provide all necessary things (such as description, data, or graph). 5 − ≤ 20 is not an inequality, an inequality should be something like 5 - x ≤ 20, but you didn't give anything like that in your question.
7. (-1,4), (5,2), we can calculate the slope. As x increases from -1 to 5, (increases by 6), the y-value decreases by 2. -2/6 = -1/3, the slope is -1/3. The slope is negative and the y-value decreases by a third of the amount the x-value changes.
9. C, because you can only hold at MOST 500, and larger watermelons is represented by 10x. I'm assuming you made an error in your question, you gave me the values of larger/smaller watermelons only, and your question asked for larger & medium and the options seem to suggest there's only larger/smaller. 10x + 3y <= 500 or <, smaller than or equal would be the better choice if available.
10. y = 2x + 10, because 2 is the slope as minutes increase by 1, inches increase by 2, and the 10 inches of sawdust are already there.
When you offer Questions #6 & #8's data, I'll gladly help you with it. The rest of the questions are correct and properly explained.
Answer:
x-intercept: (3, 0)
y-intercept: (0, 2)
Step-by-step explanation:
For a function like:
y = f(x)
The x-intercept is the value of x when y = 0
the y-intercept is the value of y when x = 0
Also remember that an ordered pair is written as (x, y).
In this case we have the equation:
2*x + 3*y = 6
For the x-intercept, we just replace y by zero in the equation, then we get:
2*x + 3*0 = 6
Solving this for x, we get:
2*x = 6
x = 6/2 = 3
Then in this case, the ordered pair for the x-intercept is (3, 0)
For the y-intercept, we just need to replace x by zero in the equation:
2*0 + 3*y = 6
Solving this for y, we get:
3*y = 6
y = 6/3 = 2
Then the ordered pair for the y-intercept is (0, 2)
Answer:
3
Step-by-step explanation:
18+18 = 36. 42-36 = 6. 6 / 2 = 3
