Answer:
c. 9 det A
Step-by-step explanation:
Given the following data;
Since A is a square matrix of order 2, we know that n = 2
K = 3
For any scalar k;
∣kA∣ = k^{n} ∣A∣
<em>Substituting into the equation;</em>
∣-3A∣ = -3²∣A∣
Simplifying, we have;
∣-3A∣ = 9∣A∣
= 9 detA
<em>Therefore, det (-3A) = 9 detA</em>
Answer:
The equation representing the relationships between the cost of laptop and Cole's payment is
.
Step-by-step explanation:
Given:
Cost of laptop = 335
Down payments = $50
Number of equal payments = 
We need to write the equation form the relationships between the cost of laptop and cole's payment.
Solution:
Now we can say that;
Cost of laptop is equal to sum of Down payments and Number of equal payments.
framing in equation form we get;

Hence The equation representing the relationships between the cost of laptop and Cole's payment is
.
A = false
b = true
c = true
d = true
