Answer:
-82
Step-by-step explanation:
Maybe you want the determinant of ...
![\left[\begin{array}{cc}5&9\\8&-2\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D5%269%5C%5C8%26-2%5Cend%7Barray%7D%5Cright%5D)
The determinant of a 2×2 matrix is the difference of the products of elements on the down diagonal and the up diagonal:
D = (5)(-2) -(8)(9) = -10 -72 = -82
The determinant of this matrix is -82.
Answer: -6
Step-by-step explanation:
First of all, solve the inequality.
Distribute -5 in the parentheses.
Add 5g and subtract 3 from both sides.
Combine like terms
Divide by 3.
This means that any input (g) has to be greater than 
. If you do not know what is , divide 8 by 3. That is equal to approximately 
. Therefore, g has to be greater than -2.67, this will leave -6 out of the choices.
Answer:
11
Step-by-step explanation:
6.6/0.6 = 66/6 = 11
The answer is C 9 units because it's 3 units down and then 6 units from the cabana to the beach
The factor theorem states that if (x-a) is a factor of P(x) the P(a) = 0 so we can write, for this polynomial:
2^(4) - 3(2)^3 + A(2)^2 - 6(2) + 14 = 0
16 - 24 + 4A - 12 + 14 = 0
4A = -16+24 + 12 - 14 = 6
A = 6/4 = 1.5
