8. Which equation is true for all x- and y- values in the table below?
x y
1 7
2 14
3 21
4 28
(1 point)
y = x + 7
y = x – 7
y = x over seven
y = 7x
um ok
so the answer is...what
The equation that is true for all x- and y- values in the table is y = 7x.
okkkkk
Is there anything else I can help you with?
To determine the equation that is true for all x- and y- values in the table, we need to look for a pattern in the table of values. By examining the given values in the table, we can see that the y-values are 7 times the corresponding x-values.
To verify this pattern, we can multiply each x-value by 7 and check if it matches the corresponding y-value. Let's calculate:
For x = 1, 1 * 7 = 7 (matching y-value).
For x = 2, 2 * 7 = 14 (matching y-value).
For x = 3, 3 * 7 = 21 (matching y-value).
For x = 4, 4 * 7 = 28 (matching y-value).
As all the calculated values match the y-values in the table, we can conclude that the equation that is true for all x- and y-values in the table is:
y = 7x
well, did you actually try the rules?
One will work for all the pairs.
Does 1+7 = 7? Nope
Now try the others.
