Answer:
-21
Step-by-step explanation:
I assume this is a 2 by 2 matrix.
![\begin{bmatrix} -5 & 1\\1 & 4 \end{bmatrix}](https://tex.z-dn.net/?f=%20%5Cbegin%7Bbmatrix%7D%20-5%20%26%201%5C%5C1%20%26%204%20%5Cend%7Bbmatrix%7D%20)
determinant = -5 * 4 - 1 * 1 = -20 - 1 = -21
Answer:
9
Step-by-step explanation:
The first thing we shall be doing here is substituting f(x) into g(x).
Mathematically, that would be written as g(f(x))
= 2(4x-3)-1 = 8x -6 -1 = 8x - 7
Now we shall find g(f(2)) by substituting 2 into the expression above.
Mathematically, that would be 8(2) -7 = 16-7 = 9

To change 1/3 c into 1 c, you would multiply by 3. So multiply 1 1/2 c by 3 to get the answer.
Answer:
x=2
Step-by-step explanation:
-3 = -2x +1
+3 +2x = +2x +3
2x=4
divide them both by 2
x=2
