Answer:
I think that the answer is C. 9^24
If it is bisector then it co ordinate points is in mid way(3,-2)
and it is perpendicular so its slope m2=-1/m1
where m1 is slope of another line passes through (4,1) nd (2,-5)
m1=-5-1/2-4=3
m2==-1/3
so equation of line is
y-3= -1/3(x+2)
Answer:
17
Step-by-step explanation:
divide 1020 by 60
1020 ÷ 60 = 17
meaning that you go 17 mph
(-5a)(-3a ²)
=
15a³
-5 x -3 = 15 ( negative times negative = positive)
a x a² = a³ ( when multiplying exponents, you add the exponents together )
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>
