7x + 2y=-12 Y=-3x-4

Mathematics
1 answer:
BabaBlast [244]3 years ago

Answer:

x=-4

Step-by-step explanation:

X would be -4 because if you distribute 2 to (-3x-4) it would give you (-6x-8) and then collecting like terms you would get (x-8=-12)  then you would add 8 to -12 whih would equal -4.

Arrange the integers 1,4,8,12,17,32 so that all consecutive integers add to a perfect square. Enter your answer with numbers sep
viktelen [127]

One possible answer is: 1, 8, 17, 32, 4, 12

I don't know if there's a methodical way to get this answer. I used trial and error. I started with 1 and looked through the list to see what adds to 1 to get a perfect square. That would be 8 since 1+8 = 9 = 3^2

The process is repeated but this time for 8. After a bit of guess and checking, we see that 8+17 = 25 = 5^2.

Then after 17 is 32 because 17+32 = 49 = 7^2.

Keep doing this until all of the values are used up. If you get stuck, then try backtracking to a previous branch/path where everything worked and try another fork in the road. If that doesn't work, then try starting the sequence with a completely different value (instead of 1).

Other answers may be possible. I haven't checked all possible permutations.

I’m pretty sure it is self explanatory because b= -0.1, c=-0.01,d=-0.001,e=0.001,f=0.01,g=0.1, and h=1

What is the next term in the sequence 58, 47, 36, 25, ...?
maksim [4K]

Answer:

14

Step-by-step explanation:

you have to add 3 to the first of the two numbers. for example 5+3=8 so the answer would be 58, and because you're decreasing each number by 10 you would have to add 1+3=4 so tha answer must be 14.
