Select the correct answer.
Which system of equations can be represented by this matrix?
2 answers:
Answer:
A) x + 2y = 4
3x + 4y -9z = 2
-x + 7z = 1
Step-by-step explanation:
The matrix form is
x y z
1 2 0 4
3 4 -9 2
-1 0 7 1
Here 0 represents no term in system.
So, the following system represents the above matrix.
x + 2y + 0z = 4 => x + 2y = 4
3x + 4y -9z = 2
-x + 0y + 7z = 1 => -x + 7z = 1
Therefore, the answer is A.
The answer is A.
You put the numbers in order of the letters and if a letter is missing you put 0

Step-by-step explanation:
Factor the polynomial.
Hyp^2 = leg1^2 + leg2^2
hyp^2 -leg1^2 = leg2^2
17^2 - 8^2 = leg2^2
leg2^2 = 289 -64
leg2^2 = 225
leg2 = 15
