Answer:
Wait..Where's the question?
Step-by-step explanation:
If solving by elimination do this:
1.Add both rows together
-5x =45
2. Solve for x
x=-9
3. Substitute x into either equation (I will use y=7x+67)
y=7(-9)+67
y=4
4. Get variables
x=-9, y=4
Answer:
3
Step-by-step explanation:
Well the square root of 12 is 3.464 and 12 squared is 144, and an intiger is a whole number no decimal or fraction. So round 3.464 to the nearest whole is 3. Hope this helps(:
Answer: TRUE
Step-by-step explanation:
An arithmetic sequence is a sequence in which the difference between each term (number) is a constant.
Given the sequence is {3, -6, -15, -24}
3 - (-6) = 9
-6 - (-15) = 9
-15 - (-24) = 9
As we can see from above, the difference between the given terms is all 9. Therefore, it is indeed an arithmetic sequence.
Hope this helps!! :)
