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:
the answer is false
Step-by-step explanation:
Assume that the larger number is m and the smaller one is n.
the larger is 10 less than twice the smaller, this means that:
m = 2n-10
the sum of the two is 38, this means that:
m+n = 38
substitute by the first equation in the second one:
2n-10+n=38
3n=48
n= 16
substitute by n in the first equation:
m=2n-10=2(16)-10= 22
based on this,
the larger number is 22 while the smaller number is 16
Alright, lets get started.
We have given point (8, -15). It lies in Q4.
Please refer the diagram attached.
The hypotenuse of the right angle triangle could be found with help of Pythagorean theorem.
d = sqrt (8^2 + 15^2)
d = sqrt (64 + 225)
d = sqrt 289
d = 17
sin Ф = opposite / hypotenuse
sin Ф = -15 / 17 : Answer
Hope it will help :)
129 rounded to the nearest ten is 130.
When you round to the nearest ten, you should be looking for;
10, 20, 30, 40, 50, 60, 70, 80, 90.
