Answer:
C)5
Step-by-step explanation:
For a 3x3 matrix ![\left[\begin{array}{ccc}a&b&c\\d&e&f\\g&h&i\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Da%26b%26c%5C%5Cd%26e%26f%5C%5Cg%26h%26i%5Cend%7Barray%7D%5Cright%5D)
determinent is given by = = a(ei − fh) − b(di − fg) + c(dh − eg)
Given Matrix
![\left[\begin{array}{ccc}-6&7&1\\a&-3&4\\-6&4&-3\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-6%267%261%5C%5Ca%26-3%264%5C%5C-6%264%26-3%5Cend%7Barray%7D%5Cright%5D)
determinent of matrix= -6((-3)(-3) − (4)(4)) − 7(a(-3) − (4)(-6)) + 1(a(4) − (-3)(-6))
-19= -6(9-16) - 7(-3a+24) +4a-18
125= 25a
125/25= 25a/25
a= 5 !
Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y.
The relative change is 2%.
<h3>What is relative change?</h3>
In contrast to the reference value, the absolute change's size is expressed as a fraction called the relative change: relative change = absolute change reference value = new value reference value reference value. The absolute change is expressed as a percentage of the value of the indicator in the prior period, or "relative change" expresses the absolute change as such. When measuring indicators in percentage terms, such as the unemployment rate, absolute and relative change principles also apply. To determine the absolute change, subtract the starting value from the ending value. Simply deduct 1,000 from 1,100 to arrive at 100 in the example. The student population increased by 100 pupils throughout the course of the year because this is the absolute change.

Answer:
80 in.
Step-by-step explanation:
The dimensions of the dilated picture are ...
4·4 in = 16 in . . . by . . . 4·6 in = 24 in
Then the perimeter of the painting is the sum of the lengths of its sides ...
16 in + 24 in + 16 in + 24 in = 80 in
