Answer:
x = -1
Step-by-step explanation:
3x - (7x +12) = 2(x - 3)
3x - 7x - 12 = 2x - 6
-4x - 12 = 2x - 6
-12 = 6x - 6
-6 = 6x
x = -1
Check:
-1(3) - (-1(7) + 12) = 2(-1 - 3)
-3 - (-7 + 12) = -2 - 6
-3 - (5) = -2 - 6
-8 = -8
correct!
If my answer is incorrect, pls correct me!
If you like my answer and explanation, mark me as brainliest!

i dont know if i can explain it right, but its kinda just like matching numbers to an equation with other numbers
google videos can explain it better and show
hope this help :)
Answer:
See below.
If the correct sum is 1155, then Ken had 495 stamps, and Henry had 660 stamps.
Step-by-step explanation:
Henry had h stamps.
Ken had k stamps.
After giving away 2/3 of his stamps, Henry ended up with 1/3 of his stamps, or h/3.
After giving away 3/4 of his stamps, ken ended up with 1/4 of his stamps, or k/4.
h/3 = k/4
h + k = 1156
4h = 3k
h = 1156 - k
4(1156 - k) = 3k
4624 - 4k = 3k
4624 = 7k
k = 4624/7
Stamps left: 0.25 × 4624/7 = 1156/7
h = 1156 - k
h = 1156 - 4624/7
h = 8092/7 - 4624/7
h = 3468/7 =495.43
Stamps left: 1/3 × 3468/7 = 1156/7
Total number of stamps left: 1156/7 + 1156/7 = 2312/7 = 330.29
The problem is solved correctly, but the numbers given must be incorrect since you cannot have a fraction of a stamp.
Answer:
D. There are points on the graph with the same -coordinate but different -coordinate.
Step-by-step explanation:
A relation is a function if and only if each element of the range, corresponding with y-axis, is associated with only one element of the domain, corresponding with x-axis. In this case, the graphed relation is not a function, since for all element of the domain, except 0, are related to two distinct elements of the range.
Hence, correct answer is D.
The domain is A. All real numbers.
