Answer:
-864
Step-by-step explanation:
The determinant of a matrix product is the product of the determinants. The determinant of a transpose is the same as the determinant of the original. Hence ...
The multiplication of an n×n matrix by a scalar 'a' multiplies its determinant by a^n, so the desired determinant is ...
We are given here the individual costs of DVD and CD as well as the total sales and the number of items sold on one day. To solve the number of DVDs and CDs sold each, we devise two independent linear equations:
(1) x + y = 39
(2) 4x + 7y = 204
x- number of DVDs; y - number of CDs
solving, x= 23 DVDs
y = 16 CDs
The greatest common factor of 64 and 96 is... uhh... hmm... 32! Because 64/32 is 2, and 96/32=3. 2 and 3 have no factors in common, except 1.
The answer is 32(2+3).
This means 32*2 + 32*3
this is the same as 64+96
Answer:
18 apples equals 6 bananas
A parabola's axis of symmetry always goes through the vertex of the parabola. In other words, it is a vertical line that goes through the x-coordinate of the vertex. Therefore, the equation of the axis of symmetry for this parabola is x = 0.
