<h3>
Answer: Choice A</h3>
=========================================================
Explanation:
A proportional linear relationship is of the form y = kx
We can solve for k to get k = y/x.
Based on that, we can prove a table is a proportional linear relationship if and only if each column of x,y values divide to the same number.
Choice A shows that y/x = 2/8 = 1/4 for the first column; however, y/x = 8/16 = 1/2 for the second column. The outputs 1/4 and 1/2 not being the same indicates we don't have a constant k value for all of the columns. This is sufficient to show that table A is not a proportional linear relationship.
-------------
In contrast, table B is a proportional linear relationship because we have these four divisions that lead to the same value (1/8)
- Column One: y/x = 2/16 = 1/8
- Column Two: y/x = 4/32 = 1/8
- Column Three: y/x = 6/48 = 1/8
- Column Four: y/x = 8/48 = 1/8
Showing that k = 1/8 for table B. The equation here is y = (1/8)x. We can rule out choice B.
I'll let you check out tables C and D on your own, but you should find that a similar situation shows up as did with table B. This indicates tables C and D are also proportional linear relationships. We can rule out choices C and D.
Answer:
I think this is the answer but I am not sure sry if I am wrong
Step-by-step explanation:
2x+y=2
y=2-2x
2x+4y=-10
2x+4×(2-2x)=-10
2x+8-8x=-10
2x-8x=-2
-6x=-2
x= 1/3
2×1/3+y=2
y=41/3
Answer:
500 - 368 = 132This means that to reach 500 from 368, you will need to count 132 ones.132 can be written in several ways including:132 = 100 + 32132 = 100 + 30 + 2For the first one:the count will be 1 one hundred and 32 units to reach 500 from 368For the second one:the count will be one hundred, 30 tens and 2 ones to reach 500 from 368

Answer:
He invested $1200 and had a balance of $1260 after 3 years.
<span>The word decreased by means subtract.
So...
Lets look at A.
A: a-b
Sound correct?
No,
Because the sentence said that "a is decreased by the number b."
Lets look at B.
B. b-a
Sound correct?
Yes,
Because a is getting decreased by b.
Your answer is, B.
Hope this helps!(:
