Answer:
3rd Matrix
Step-by-step explanation:
When you start putting the coefficients in as the matrix, you see that -9 has to be the 1st number, so that eliminates choice B and choice D as answers. You are left with choices A and C. C is the correct choice because when you plug in the second equation, your coefficient is -5, not 0.
If it is 41/3, then the answer would be 13 and 2/3. If it is 4/13, then there would be no mixed number. Sorry. It is hard to tell because there is no slash to represent where the numerator and the denominator is.
Answer:
b=24
Step-by-step explanation:
you use a^2+b^2=c^2
so 10^2+b^2=26^2
100+b^2=676
subtract 100 from both sides
b^2=576
then sq rt the 576 to get 24
Answer:
7(x+3)
Step-by-step explanation:
7x+21
7x = 7*x
21 = 7*3
We can factor out a 7 from both terms. What remains is what is inside the parentheses
7(x+3)
Antelope: About 32 Days
Boar: About 12 Days
Dear: About 3 Days
Buffalo: About 42 Days
