Order of matrix Q is 4 by 3
whereas order of R is 4by 4
In order to add two matrices , they should be of same order.
The square root of 30 in its simplest form is 5.5 ( I think)
If you are given a unit rate (ex: $0.59 per ounce) then you can multiple this by the weight of the cereal to find the cost of the entire box. Do this for both boxes, and then compare the costs.
Hope this helps. I'm not sure that I'm on the right path, but I can help you further if you provide more details.
Good luck!
Using the concept of y-intercept, it is found that the response that is not correct is given by:
B) Replace x with -x.
<h3>What is the y-intercept of a function?</h3>
It is the value of the function when x = 0, hence it is the point (0, f(0)).
In this problem, the function is:

The y-intercept is given by:

If we just replace x with -x, we still have the same expression as above, hence the y-intercept does not change and option B is the answer to this question.
