<em>CA </em>⁻¹ is undefined because there are more columns in <em>A </em>⁻¹ than there are rows in <em>C</em>.
2 1/2 = 2.5
12 1/2 = 12.5
This means you can calculate how may times it goes in by dividing it and rounding the number down:
12.5 / 2.5 = 5
*5 can not be rounded down so it stays the same
This means that 2 1/2 goes into 12 1/2 5 times. Hope this helps! :)
The given equation is
x intercept
To find the x intercept, we have to plug 0 for y and solve for x.That is
So x intercept is (6,0) .
y intercept
To find the y intercept , we have to plug 0 for x and solve for y. That is
So the y intercept is (0,-9) .
31/100 represents the yellow marbles because 3/10 = 30/100, 2/10 = 20/100, and 19/100.It all adds up to 69/100 marbles.
