Hiiii! My teacher gave out some practice problems to help prepare for the big upcoming tEst.. I just don't remember hiw to do fhese problems.. Irs just hard for me.. these are not graded, I just need help so I can (hopefully) ace the test :)
Questions!:
Write an equation to express y in terms of x. Use your equation to complete the table
1. --------------------------------------
x- 1, 2 , 3, 4, 5
--------------------------------------
y- 7, 14, 21, 28, ??
-------------------------------------- ________
I can tell y jumps in 7 but I don't know the wquation
Sorry for horrible spelling. I am typing quickly on my phone screen, very hard to type!

The data values have been put in ascending order.
Hi! I'm here to help you out with your practice problems. Don't worry, we'll figure it out together!
To find an equation that expresses y in terms of x, we need to determine the relationship between the x-values and the corresponding y-values in the table.
Looking at the y-values, we can see that each value is obtained by multiplying the corresponding x-value by 7. This means that y is always 7 times the value of x.
So, the equation to express y in terms of x would be y = 7x.
Now, let's complete the table using this equation:
1. x = 1, y = 7(1) = 7
2. x = 2, y = 7(2) = 14
3. x = 3, y = 7(3) = 21
4. x = 4, y = 7(4) = 28
5. x = 5, y = 7(5) = 35
So, the completed table would look like this:
--------------------------------------
x | y
--------------------------------------
1 | 7
2 | 14
3 | 21
4 | 28
5 | 35
--------------------------------------
I hope this helps! If you have any more questions or need further explanation, feel free to ask. Good luck with your test preparation!
